I played a game that left me scratching my head a bit. I'm not sure if my errors were uncharacteristically bad, but during the game and during analysis it wasn't quite clear to me where the major mistakes were (having three weak groups was definitely one). All input is welcome.

There is a theme to the opening comments. :)

Main focus: Getting enclosed, even if you make small life, is usually not good.



Edit: I have been thinking about what lost the game. No one thing, OC. Black came out of the fighting on the bottom side behind. Then :b71:, although joseki, was passive. :w76: gave Black chances, but :b77: should have been the jump attachment, attacking both sides. Then, :b79:, although maybe OK in itself, led to a complicated position where Black had difficulties. Finally, at least as far as I looked, the hane, :b87:, was an overplay, leaving Black with too many weaknesses.

EDIT: I see that Bill posted while I was typing. Hmmm...I still don't like your direction of play at move 25, even if he says it is good.

Nothing against your suggestions. In fact, attacking the White group on the right side might be best. But other moves are quite playable. If Black undercuts the White group in the bottom right (while making a live group himself), and White does not reply (and I think he should not), then Black M-03 is an attack against that group.

Not that that play occurred to me, but once Black plays it, its value becomes apparent. It is playable. :)

Thank you all for comments :) It does look like I underestimated the strength of the wall a lot.

Some losses just look like I could draw some general conclusions from them. Other than that, I still have absolutely no clue what I'm doing. Also, it sounds like playing 2 is the key!
I think the main takeaways are to remember the shape in the bottom left (how white's tiger's mouth encloses black solidly and black's push prevents that and leaves potential for a push and a cut), avoiding getting enclosed, avoiding heavy play near strength and looking for counter-attacks. I really liked your idea to keep the three white stones on the bottom unsettled from the start, Bill.

@Joaz: Good point about not settling until necessary. Also, jumping out of a pincer after an approach like this always seemed like a no-no to me. What's different between a low 1-space pincer and a high 1-space pincer in this regard?

I was around your strength when I learned about plays like White C-07, even if it does not carry a threat against the corner. I did not believe it was so big, but I tried it out in my own games, with great success. :)

Hi yakcll,
Some suggestions for :b25: .
( DeepLeela is a 'freebie' bot; other bots with better software and hardware may give different numbers. :) )
