Beginner Go Series E6: Ending the game?

what is up guys in sente here and I'm here with the last I think video for the beginner series now I made this beginner series to go a long time ago and it's had really great feedback and really great success but there's been a lot of consistent comments that beginner to confused about that is when does the game end not only when does the game end but what happens to dead stones when you end the game when are you allowed to play inside your opponent's territory which is when you're not and so there's actually a lot more confusion about ending the game that I have thought I think just because I haven't been a beginner and so long I kind of forgot how confusing the end of the game was but want to try to remove the remedy that now with the video on when does the game end how to handle bed stones in your territory and all those questions that I have been asked over time so I hope you get a lot out of this and I hope this is sort of the last piece and the beginner go players arsenal that they can use so without further ado let's get started okay so here at position black just played his move now even if you're a beginner you can probably know that have an intuition that the game isn't over yet what I want you to do is identify all of the places that need to be sealed off for both sides so in order to end the game all areas of the board need to be controlled by either one player or no players it's controlled by a player if the only thing surrounding those points or those intersections are stones of that color or a border like the edge of the board if there is space that is that is touching both players so stones of different colors are in contact with the empty space and there's no clearly defined border of that is not considered territory so once take a minute look at all the places that need to be sealed off and on pause the video and then we'll go from there okay so there's a few places that we see right away so there's this area there's this area this area and this area that are not sealed this area is fine we can see that the only thing surrounding these points are the edge of the board and stones of one color so that's good so these are really the four places that are not sealed so what let's start one at a time so a is not sealed because you have yep stone surrounding them surrounding these points but it's missing one right these points are not surrounded on all sides by stones of the same color there's like a leak here so in order for these points to become blacks black needs to play a move here or here if black plays a move here now all we see that he gets three points of territory and another point of territory because these three points are surrounded by just black stones and this is also surrounded by just black stones if he plays here instead he only gets two points this point is not surrounded by all black stones yet so that's technically not considered a point he could get that in the future but in one move that does not met him this point this area over here we can see those two places two breaks here and here so if white gets this move in this note then all of these points are White's now because they are surrounded by just the border and stones that are all white and same drill goes for the other areas of the board so this area again we see a break here and here and then for this area we see a break here simple enough right so you know the game is over when all of the areas are completely sealed off what a lot of times is more complicated than that let's say let's say white plays here when you're beginning when you're a beginner a lot of times you don't really know whether something is yours or your opponent's territory not you think you might be able to capture something or something like that and you or your opponent might play things that seem to be blatantly in the other person's territory so how do you handle that well prisoners are all worth one point in go so a captured zone is worth an extra point for you that being said if you think that your opponent's move if left unresponded to is a threat then you can respond then keep making moves you can keep responding and then you can just capture them now notice that white played three stones in your territory and you played three stones in your own territory because each white stone is a prisoner that means that the score has not changed you gained three points from capturing three white stones but you've lost three points by putting three black stones in what could have been your territory that means nothing changed at all and you still have the same amount of point you started with so if your opponent is doing something and you think that it's a threat or you don't aren't sure if it can hurt you or not in your territory you never lose anything by responding as long as you put the same number of stones in as your opponent and you end up capturing them at the end that being said if your opponent does something that you think isn't worth responding to or there's no way even with an extra move your opponent can do anything you can just go somewhere else or if it's the end of the game there's nowhere else to go past the turn and if he plays another stone in your territory then you can capture that and then you have won more points than you would have initially so let's show that game is over right everything is completely filled there are no points that are not surrounded by somebody so let's say black plays here and you think to yourself huh I don't really need to respond to that do I or maybe you do need to respond to it um take a minute think about if you would respond to this move and if you would respond where you would go like I said responding would not change the score so there's really no reason to not respond unless you're absolutely certain it cannot live what you can do and that's totally fine and I'll tell you why you might want to do that later but for now just see if you want to respond or not and unpause the video okay so in this case you really don't need to respond because there's no way black can live in this situation if white just passes the turn and black tries to keep living white and just crunch black down like so white takes away blacks other eye and just like that black only has one eye to his name eventually if black keeps passing white will fill these two in and then capture all the black stones now what's the difference between not responding versus responding well if you don't respond until he plays one extra move now for every move you play and if this is dead and this is a dead group and the algorithm takes it off the board once you and your opponent finish the other moves then you have placed one he has placed one more stone in your territory than you placed in your territory because you gave them two moves before reacting instead of just one that means that you get one more point versus nothing changing like the other scenario so just visually he put four stones in his territory you only put three which means you get four points and you lost three points you had a net gain of one point but it's as soon as he played his move you decided I'm not risking it I am just going to respond right now and every move he moves you respond and make sure everything is nice and dead then the score is exactly the same the next question is are you required to kill your upon the opponent's stone that's not a good question so let's say you get your opponent in a situation where there's absolutely no way to live is there any reason do you need to play a1 and b1 to take those off the board completely now this is a very ambiguous question because it depends on the situation but most country explanation I can give is that if you're surrounding stones are unconditionally alive and your opponent surrounding stones are not alive unconditionally those stones are dead and you don't have to send the work capturing them and the algorithm will just take them off the board so we can see here that no matter what black does to try to capture these stones white has like four eyes in this group and black only has one so there is absolutely no way black can make his group live the burden is on the invader to make to kill his opponent so if this group is not alive as it is but these surrounding stones are clearly alive you don't have to spend the work capturing the stone you can just leave it pass he passes where she passes and the algorithm and the computer takes those off the board for you or you designate the dead stones with a click and then you move on and then then the game is over now a big part of ending of knowing when the game is over is knowing what weaknesses there are in your opponent's position unfortunately that takes time that's why the ending of the game is so confusing for beginning players let's imagine that these moves are made just like this white plays here actually n white ends up actually instead of playing there white plays here like before we had this example would you respond against this move is black if you're not very good at reading or you are not used to playing go you might think that there's no way this can do anything and you might pass the turn or you might not respond to it but actually this is a very big threat because if black doesn't do anything white has this move which is an authority on this stone black helps to defend and then white gets the capture and now his entire area is completely destroyed black has to try to defend just simply like this and his entire corner has been reduced to only three points so the life and death of groups and the weaknesses in shape plays a big part in what is dead and what is alive and when it's time to end the game Don player will think the end of the game at the will think the game is over at a much different point than say a beginner player so the best advice I can give for beginner players trying to figure out when the game is over is to make sure all of your territory is sealed and if you think there's a weakness in your opponent's shape that you want to try to probe at attack or expose by all means do it this is experimental you're getting your feet wet you're learning to fly you're trying to figure out how to play this game so experiment all you can this you know if you think this probe would do something short play it maybe you think that it when he plays here this is a strong loop but then black would play here and you would realize that that actually didn't work but you tried it and then that's fine the way that's go is tour because prisoners are worth a point it is very easy to just defend your points and the score at the game doesn't change like I explained to you a great example is this white group here if black plays here and white makes a mistake White's entire group could die say white plays here to Atari the black stone that's actually a huge mistake black can play this Atari now retiring these three white stones white is forced to capture black now Ataris the three white stones again white is forced to fill and black can actually capture everything and then because this doesn't have any eyes either this group is captured so if White's not careful and black plays an endgame move something as simple as this and white responds incorrectly and black sees something that white doesn't the entire group could be captured when you would think that this is White's territory so reading plays a huge part in the endgame understanding what groups are safe which are not which shapes are safe and which shapes are not when you get more advanced back here in a situation say like here you see this is a potential weak point if black probes here and white answers incorrectly this is the incorrect response because what this does is this black is black the opportunity to play here now if white tries to see a black off black cuts white tries to capture but black is one move ahead and black actually captures those two stones if we take it back to here and white goes on top instead to protect from being cut black can under connect and he has invaded White's territory and burrowed out from underneath so the year at the end of the game has always been a very tough thing for beginners to grasp because so much of it is depending on how good you are but you just try to follow the principles of making sure all of your areas are sealed before passing your turn and then when your opponent passes and you score the game making sure that your opponent plays in your area and you're not sure if it can live or not to try to kill it make sure to expose weaknesses and experiment around and also you don't need to capture dead stones that are in your territory as long as your surrounding stones are alive right if you remember this right this only has one eye so this group is dead white doesn't need to spend an extra move making sure it's dead because there's no way black can capture the outside group there's no way black and capture the outside group this is invincible this is dead the computer will just mark it as dead and you don't need to worry about it so that's sort of my crash course for the end of the game and some of the little ambiguity that pop up at the end of the game I certainly can't cover all the little nuances in one reasonably time video so definitely ask questions post them in the comments see what other people have to say about it and anything you want to know just put in the comments and I can try to get back to you and and respond but so I hope you learned some stuff and I hope this video was useful for the beginners I hope this was a good ending to the beginner go series and please let me know what you think in the comments below love to hear from you and create luck in your games and I hope to see you on the grid [Music]
