https://online-go.com/game/20004487 I had a very fun game against a stronger player this morning, and as we all know, it's harder to learn from your wins than your losses. The other person left without reviewing. Would some of you please help me learn from this match? Thanks in advance!

A few thoughts:  not an awful move, but a bit unusual. Responses like C6, E3 or tenuki would be more usual. would be better at D7. Playing on the second line is useful to make life, but here you are already safe. It's better to try to access the center while threatening to separate two white groups. is small. There are bigger points on the board. would be better at P2. This would connect two of your groups, and make the O6 group stronger, so that you can attack M5 afterwards.Move 100 would be better at J12. You have many friendly stones around, so your opponent can't cut. It's better to be ahead of your opponent, rather than push from behind. Move 150: you just threaten one stone?? There are bigger moves on the board. Move 216: what are you afraid of? Move 224: what are you afraid of? |

I like your comment at move 34. Good to see your sense of priorities :-) There are two areas where I think you can improve quickly. First is your sense of good shape: at the moment you're missing a lot of basic instinct moves. Examples in your game: at move 8 you could have played Q15; move 18, D16 (although there are other good moves in this position too); move 54, P2; move 72, E17. With practice, these are the sorts of moves you'll play almost automatically. Good ways to improve your instincts are to watch games by stronger players, and to quickly go through a bunch of examples at the Neural Net Go Problems site. Second, as hinted in the other posts, you give away a lot of points by defending when you don't need to. As a general principle, before playing a defensive move, you should ask: if I don't play here, then exactly what move will my opponent play? If you don't see how they can punish you, then you shouldn't defend! Once in a while you'll lose a game in a horrible way, but you'll learn a lot from those experiences. If you do it the other way -- being too cautious and defending every time you're not sure -- then you won't improve as quickly. |

Without thinking much about it, and just going on feeling/intuition, the first move I felt was wrong was this: Interestingly, though, my intuition/feeling was wrong. I felt like playing here: which is logically bad since white can have nice shape with the marked intersection. And AIs seem to think it's bad, too! |

jlt wrote: Move 216: what are you afraid of? Move 224: what are you afraid of? Your advice is spot on in general. I think these two questions in particular, though, got my attention! I went back and took a look at what, exactly, I was afraid of in these instances. I think I had good justification for these moves. I've lost far more territory than I like to admit over the years thanks to leaving behind formations like this and failing to read it out when my opponent cuts. My play has been conditioned by hyper-aggressive players, unfortunately, and up until very recently I haven't been able to even begin to approach punishing them. That said, looking at it now, I can see that the marked Black stones are not dead, provided Black plays at a. My problem with this is, if White plays at a now, I don't lose my 5 stones, but I do lose 4 points of territory that should have been mine, because I have to connect at b. So, my mindset is to connect and prevent White from having any possibility whatsoever of going this way. Black's shape here is also very ugly, and I don't like that I only have 2 liberties left after this exchange. White could keep pushing and pushing with further shenanigans, and I just didn't want to even go there. As for 224: Immediately preceding this, with move 223, White had just taken 4 stones and now had a cutting point (a) into my center moyo. They could have leaned on my marked stones, or tried to resurrect their marked stones. Granted, I could have played it out, I don't think they had a serious chance, but I've been wrong before. Many many times. I wanted to take away that possibility. |

You don't lose 4 points of territory. You play twice in your territory, which loses 2 points, but the two white stones are prisoners, so you gain 2 points. Overall you gain nothing and lose nothing. That said, I think that capturing instead of playing at b is better: Quote: As for 224: Immediately preceding this, with move 223, White had just taken 4 stones and now had a cutting point (a) into my center moyo.

Many many times. I wanted to take away that possibility. There is nothing to be afraid of IMO. Points a and b are miai (if White plays a you can play b and vice-versa). You have many black stones around which are almost all connected, White can neither kill your stones nor make a living group inside your territory. |

Oh hey, you're right, capturing is way better. It seems I need to start swinging the pendulum of play back towards more confidence. I'm at an extreme of defense right now but that's too slow. I keep forgetting that prisoners count, too, haha. The more they push, the more they stand to lose. |
