Go Fighting Strategies #2

[Music] [Music] hi everyone my name is Stephanie and welcome back to our fighting strand a series in this video I'm going to talk about the five most exciting fighting moments in February so let's get started by 3220 q so this is the game so why don't we analyze the port situation first and then we're going to jump into the fighting moment so what happened in the actual game is both black and white are fighting in the center area here and as we can see this whole group here the dragon doesn't have one eye yet but a white group over here on the right side is not in the settled so in the actual game black block 2 here and black was trying to make some eye space on the top and also black is looking for the next vital point on the top now you can see there's two eyes so of course so right now white actually is facing a very hard time as well because when we look at the whole board black has the has a one huge corner here and some territory on the left and some potential on the right side as well but white doesn't have a lot of territory on the board there's a few points in the center and the corner is not blocked yet the side is not in close yet either so what white has to do is what has to kill this dragon in order to win this game or what has to get some some benefit from attacking but most likely either what is going to kill this group and when or black is gonna live on the board and black is gonna win so an actual day and white played the vital point and then black block to here so after that they change move it's not going to be a live shape anymore even though is a blacks turn it will add those here that's a pent for but now it's as whites turn so what is going to take the two by two points in the bed for so in the actual game white realized this group is not a sad ode and if wait use extra stone here or somewhere on the top and there is a vital point here to take all the eye space from white so in the actual game wait decided to play another move to block here and get some ice base and now this whole group is alive but what wait missed is black actually has a tesuji in the corner so that's a sente we have talked about that move black is looking for the block here and now black has two eyes so what has to extend so in the actual game white worth was thinking the whole corner the corner is already live if we don't have these two exchange moves on the board if black tries to block here and after wait descend and now we can see there is a five eye space and in the corner and that's a bend shape so it is a live shape but after this exchange move why is the corner in danger now alright so black actually has a a tesuji which is the one to point and now of course what has to block here otherwise all the eye space is gonna be taken by what if I black so after that exchange move if blacks still used a simple block here that's a still bent five that's a life so it was can happen in the corner it black cuts here wait will Atari on the top and this stone is that the stone is down and that's also two eyes so the second tsuki is the clamp right here it looks very strange and odd ray is on the first line how does that work all right let's let's see you so if so of course black white now needs to expand the eye space because it waits connected back and then black is going to block on the outside now you can see there's been three but black has already take the vital point so what has to expend the eye space and then black will block and white blocks and now you we see a double Atari right here and if black white connects here black is going to capture the other side if black of white cap is here and the black is going to capture the three stones so the corner is dead but what about what goes here so now I put a black stone here in in Atari and also I have a connecting move here to make two eyes is it alive or not yet the answer is the corner is still dead because the push that's also a sentiment and then black it's going to sacrifice the two stones and then throw in again and now you can see the whole corner is dead all right so this isn't what happened in the actual game and eventually black was alive the entire group that was alive and then black has a lot of territory on the board and eventually black won this game so now let's look at the next example alright so this is the game played by 19 - thank you players so what's going on the board alright let's look at the left upper left side over here so the black are the white group in the center over here it's in danger it doesn't have any eye space and so when we look at the whole board situation both plucking and white are having same amount of a territory all aboard black has is some territory on the on the bottom and a huge corner over here and some points on the top so what is a controlling the entire left aside and some potential on the right side so both players are fighting over here this group white group in the center is not alive and let's look at a blacks corner so blacks corner is not it's not settled but it's not dead if black is able to live in the corner now we can see this entire dragon is already surrounded by black and what has to run toward to the bottom and looks for some ice base in the center but it seems very hard so that means if black is able to live in the corner most likely black is going to win this game because it's very hard for a way to make this group alive so what happened in the actual game is white played Ohana here and it tried to attack the entire corner if white is able to kill the corner of course this dragon is alive and then black blocked here tari that's also sent a because if black this is simply connect and then what is going to kill the eye in the middle and now we will we can see there's not enough I space so black Atari here and what has to connect and in an actual game black actually made mistake black and was able to make this whole group alive but since black didn't see that test routing in the corner and then black a connected here and a white cut and kill the eye in the center and now we can see if black could take the one one point and what is going to sacrifice the two stones and throw in again and now the entire group only has a one eye so where is the tissues to suit you that I was talking about so right now black has to use a kazoo G which is the call to under the stones so where is the - suji is right here so why is the sushi it looks like a dead group as the pyramid forward bent three in the in the corner and then of course white is going to take the value point and if like a captor this dough still the whole corner is dead but what black has is black it can make the eye in the center and let wait kill the four stones and then black is going to Atari the two stones on the back and fours way to capture the four stones and now you can see there's a weakness of weight it's right here so black now is able to kill the three white stones and now you can see there's one eye in the center and then there I in the corner alright so you might have another question if cutting point doesn't work for Wade what about I connect the stone back and now as far as the corner doesn't have I then the entire group is still there is only have one nine but what happened is black king keep Atari the three stones like that and then there's another weakness on the side which is over here and now how black is still able to kill the entire white group on the side so the group is alive alright so what happened in the actual game is black didn't see this and black didn't see the under the stone - suji and bukka connected here and white kill the eye in the center and black char is very hard to surround here and put white into a capped erase which is another term for liberty fight but since one has a lot of liberties and eventually the corner is dead alright so now let's look at the next example alright so this is the game played by night two one cute players so like Europe we're going to analyze the boy first and then I'm going to show you the moment so in this game so right now black to play it's blacks turn and then it looks very peaceful on the board both player are taking territory very peacefully black is controlling the upper right corner and some territory on the upper left corner and to some potentials on the bottom as well so white has entire left side and some potential in the center and a few points on the right side the corner is not enclosed yet alright so it looks very peaceful in this game whoa first time I went looking at the scheme I thought black is going to either protect the side by blocking here or black is going to do something on the side because there's some territory there's some potential here and these two places are the biggest two plays on the board but I didn't realize the sudden-death is actually coming so where is the sudden-death is right on the top so the first time when I looking at this shape it looks like a live shape because wait has a lot of eye space on the top it's really hard to think this is a dead shape in black reduce the eye space from the outside and a white can block and if black keep reducing the eye space and now you can see it will be a second the double life so double life osechi is considers alive how is this sudden death all right it's we could and to you what black is show the the next move on the board and then I realize wow this group actually is not alive yet okay so what happened in the actual game is black peeped here that's a sente and then wait is still didn't realize the danger is the coming and the white connected with one second and then what we're thinking if black goes here that would be the same thing that would be a double alive those double of is pretty small right now since we have a lot of big places on the board but after that black house I throw in here and that's also Center and then black is going to play this move now you can see if white folds makes the eye on the top since I made this exchange move throw in and capture now when I tore a back here there's not enough I space on the top anymore so if white descend here and in black is going to kill the bit for all right so when weight was saying this move on the board white stop and that took some time to think and then wait play the kosumi here so why do you stow what's trying to expand the eye space on the top even though black I can capture this down but at least there's a KO but that's not the answer so after the Kasumi black extended here and then now you can see if white connects here there is a ladder so now everything is dead on the top so if wait ATAR is on the top block of captures and connect the two stones back and now you can see there's not enough ice based on the top four ways so eventually this group was dead and then black who won this game alright so let's look at the next example now alright so next game is played by one two four ten players so what's what's happening on this game is both black and white are having a small fight in the corner right now but the fight is almost to set out so the corner is almost alive and a weight is almost connected so what happened in this game is white play this move and white block it on the block a block on the top and black of was thinking was hoping white pull the stone back and so that block you can Atari here connect first and Atari here and now since I have Atari over here I don't have to use extra stone tool F in the corner it's already alive if weight goes here later I can make the eye on the top and if white destroy the eye here I can just send here and make to event straight-4 so this is what black was expected and then after black left in the corner by sente and then block you can do something on the board either invade here to break the potential here or expand to keep expanding the potential in the center this is what black expected but in the actual game white was very greedy wait thinks okay this looks like a center for me so why don't I kill the still first and then pull this don't back so at least that get some extra points and plus I created a some weakness the cutting pointed Center as well but white didn't see the danger is coming and he didn't realize this is actually a losing move so black white was thinking even black Ataris on the top and then break through here the corner is still Phi and black is still half has to use it another stone to connect back but since there's no Atari here the corner looks more dangerous so that's why way was not a worried about Atari here not a worry about black cut through in the center and in the middle like this but wait didn't realize the danger is really coming so where is that powerful move where we're talking about is right here the one space jump so what's the difference between the one space jump and Atari there look exactly they look exactly the same right so if white blocks here and no block it can still connect back meet black a student needs to connect this back otherwise there's a Persian cut so now that's just exactly seem very sure as we talked about before so how is this move so powerful the one space jump it's because after white blocks here instead of connecting back black now is going to sacrifice one more stone and Atari and forged wait to capture here and now you will see after that exchange move there's not enough ice base for white on the side anymore and then I'm gonna play the attachment move here and kill the second eye from white so what happened in this game is a weight was trying to break through in the middle but since Black has a strong wall on the bottom and the left side is also connected and eventually this guru was dead alright so now let's look at the last example alright so the last game is played by five to seven nine players so what's happening in this game is both black and white are having a fight in the middle right now but the corner right there is not alive yet so white has to use extra stone to live so this is the last to move white played on the board the the reason why white played this move instead of living the corner directly is because white was expecting that the sente move white was hoping expecting black to connect at first and then what it's going to use all the sin tastes and take all the eye space away from black and later on there's still some AG's in the center but however what happen is in the actual game is this is actually a mistake why didn't realize wait black actually has a soo-ji a very good move to prevent the cut and plus black is going to kill the the four stones in the corner so where is that move as right over here so the one to point why does this move so powerful why is this good move so after I have the stone in the center let's say weight will cut here and then the five stones now are separated but since I have the stone here then I can use the watch and Atari on the back to create a snapback for weight and now you can see these two stones are dead and everything is connected all right so after this move what we're thinking okay how how should i do then how should I fix this problem so if weight Ataris here and then black is going to kill the eye on the table so now you can see the whole corner it's already dead it doesn't have a two eyes so white played throwing move here and try to make a coal but unfortunately that's not a KO because black is still have to move right here if weight connects here then the black is going to pull the stone back if black doesn't play this move and then now the two stones are dead these two stones are in iself Ataris or the corners of lives so black needs to pull this stone back and whit captures block two connects here so now the cut is still doesn't work because black is black has the three liberties and the white only has a two so black wins still Liberty fight let's go back and after throwing and black a captured and weight a target here and do black kill the eye on the top and this move doesn't work this move also doesn't work because black down can squeeze here and kill the eye and now the corner only has one real eye alright so connecting here doesn't work and blocking here also doesn't work so how about a capture here does that work no the answer is it doesn't work either so black and out doesn't need to play that actress stone in the corner instead of what you can just simply connect and as white captures here this I as a full-size if weight to form this I and black you can sacrifice the two stones and throwing here and now the corner is dead alright so these are the five most exciting fighting moments in February if you like the video don't forget to give me thumbs up and if you
