well, i lose this game by 2,5.
quite surprising cause my counting says i lead a little
can anybody point out what should i do n what shouldn't
i'll really help
thanks

this is the game:

Just a few notes on the end game, where you could have picked up a few points. Obviously take this with a grain of salt, we're at the same level...

235: Isn't this dame? At any rate you can't lose more than a point by failing to connect.
239: Again, I don't think that cutting your groups is worth that much for W, so I would treat this as 1/3 of a point. K2, F14 and E1 all have large follow-ups for you.
240: You could have taken E1 and F14 first before playing a gote move.
255: S5 saves 2 pts.
263: B5 could be worth 1 pt more than B13 (because after W takes B5, he plays again), if there were a point somewhere that you missed.

I moved this to the 'game analysis' forum, where it will probably get more replies.

Move 9 at F16 looks way too loose. If we look at the corner ( renumbered to show just the moves in that corner ) you are essentially playing a taisha with white having an extra move at D12. As the taisha often explodes into half a dozen or more running groups desperately seeking life, that extra stone is sure to benefit him.

Worse yet, you abandon your newly placed stone at F16. Even if white 3 were not there, black 6 is inconsistent with black 4.

If you are going to play 4, you have to back it up when he attacks it.

But you end up with the extra stone just sitting there, separated and useless:

A few ideas:

quite true...
235 is a missread (actually, i didn't read at all... )
think i could kill 2 stones there
and about 255, well, i forgot that i already kill the white group in middle right
for the rest, i have no excuse, clearly my fault

thanks

@joaz...
i'm kinda experimenting there... i know it turn out silly...

@edlee...
thanks for the pointer but i think if u can give deeper variation it'll be really great
like the move , why it's better to continue pushing
can w tenuki there? i think w group already has an eye and a base for another eye

Because you played E6 in gote, and locally if you add a move in gote,
then pushing at H6 is more efficient than E6:
Black H6 has a follow-up hane at J5 (which also has ramifications with the B hane at F2),
whereas , turning at the same point H6 gives W the follow-up atari at G7.
So locally, H6 is a shared vital point for B and W -- no deep reading needed.
