Hi all
Feel free to comment and spot my mistakes. The more I play the better I feel during a game. Was played more or less well by my side?
Thank you

Just a few quickies: 14, 22, 24: too small for the opening. 49: yes, a terrible move by black. 64: very bad shape. If you feel you need to add a defensive move here, play something that is also productive, such as N7 or M4. 86: very small. I don't know the very best move, but things like G2, R14, E15, B10 are all much bigger. |

Thanks for the review. I have a question: white 42 for me is somewhat obliged (but since i'm a beginner i think i'm wrong). If my opponent plays there I think my position is mess up. I tought that was a needed defensive move against invasions. Is it too slow? At my 82 move my plan was to steal some territory, and since my opponent approached my stones I connected them. In game I thought that it was too slow but giving the opportunity to strenghten his moyo on the right seemed to me a disaster. At move 94 a stick a snake in his nest and I considerably reduced his territory. What was the correct direction of play before that sequence? Thank in advance |

About move 14; I think it's wrong to call it slow. A slow move is a move that does something useful, but where there are bigger and more useful moves to be made elsewhere. 14 is quite simply unnecessary and worse than a pass, losing a point of territory. A slow move makes progress towards your destination, but in too low a gear; 14 on the other hand put the car into reverse. I imagine you saw there was a cutting point at r2 and, having suffered from other cuts in other games, you wanted to defend it. However, a cut like that on the second line can be captured against the edge. Take a look at viewtopic.php?p=172664#p172664 to practice reading if you can capture stones by trapping them against the edge from various positions of varying distance from the edge of the board. Move 42 obliged by what? Are you perhaps thinking of this shape, where  is not obliged but is certainly a good move to avoid white being annoying around there later?It is certainly true that if you play 42 as the turn topaz recommended then there is a bigger gap which black might be able to invade. However, it might die, and even if it doesn't white could profit from chasing it: it makes it difficult for black to win. However if you play 42 as in the game black doesn't need to invade any more but can safely reduce from the left side (which also increases his territory there) which is easy. You need to get more than 50% of the territory (+captures) to win. Your 42 is like saying "Please can I have 40% of the territory?" Your opponent can then answer "Yes, be my guest!" and safely give you what you want and you lose. It is generally a better idea to ask for 60%* and have a fight which you might win or might lose than just peacefully lose with no fighting. Having said that 42 is not actually such a terrible move. *A highly skilled player can always ask for 50% or just a tiny bit more and then patiently wait for his opponent's mistakes to gain an advantage. Lee Changho in his prime was probably a good example of this style of superb positional judgement. |

Maybe not the best move - in this area, I prefer G3 - but your 42 is still worth something. It is an error, but a small one compared to some others, so I do not think this one is so important to focus on. About 76-82. This sequence may look inelegant, but there was a lingering threat. I have not attempted to read it all out, but black might be able to cut starting with Q11, so defending this is not necessarily bad. There may be better ways to defend (R11? R14? not sure what is best) but the idea is not a total bust. |
