White's move is hard to pressure, because it has miai to extend to either side and can't easily be confined to the top. It's also not urgent, because it's not opening any big aji into black's left or right sides or upper corners, and being one stone, it's light. As such, I think it's clear that the right play is to tenuki. Whether white's move is right or not is hard to say, since the 'correct' move against 6 stones is probably to resign, but it certainly doesn't have the same pressure as a direct approach to a corner, although it potentially increases the value of an approach now. From an opening perspective, prior to white's move there were two big open areas left on the board, the top and the bottom. They're exactly alike, so it's easy to treat them as miai. It follows that the right choice for black playing tenuki is to take the other in some manner, and practically the only moves are the game move or the star point right above it. This isn't to say that there aren't other moves that are perfectly viable and will lead to a winnable game as well. With 6 extra stones on the board it's hard to play a truly bad move at the beginning, before white's able to start confusing things, but I feel is beyond reproach. |

I hadn't realized that some of the early comments were already revealed! In any case, thank you to one and all for your observations. Some post-game thoughts. I see that my first major mistake was playing P5 instead of S5. Yeah, a hane in similar positions had turned out poorly for me in computer games so I tried the atari instead. But I see now how much better it would have been to seal the side. Now that I see the comments. Yes, I saw that I had a net for the stone at J6 when I played J7. I think that it was the first time I've ever played a net in an actual game--exciting! (As opposed to finding them in many problems!) In retrospect, the move was way too small. I really need to think bigger and globally. When I played move 82, I saw the sequence to move 87 but overlooked the squeeze tesuji until we reached that move. (I was thinking of the hane underneath, when I could connect out.) I felt like my game was desperate after this, and it went rapidly downhill. Move 96 was too optimistic; I thought that I was thinking bigger, but that just got more stones killed. With move 100, I thought that I would try to salvage something on top. (The left side stones all being dead.) But being too timid to play the cut at J15 finished any tiny chance left to keep the game competitive. @Bill: I guess that I was playing tic-tac-toe! I feel unworthy, but I shall ever endeavor to improve, though the results be ever so meager. |
