Lost, but where was the losing play?

[bleep69]

Hi, I played this on KGS last night, and was reasonably happy, despite losing. I lost my way a bit in the middle of the game, and seemed to lose sight of what I was trying to do, any pointers would be greatly appreciated. I have put my thoughts down as I remembered them from during the game, and a few that I had after:

Thanks, fwiffo, for the very clear posting instructions!

6: Yes it is bad in this case.
13: The relationship between G17 and L17 is not good; White can break through with H16 or K16. Furthermore he has the connection at L18 available, so this move in fact hardly pressures White at all.
16: Now you see the consequence; J15 is already damaged.
27: Too slow. Gives you little.
29: No, C6 is fine and is better than D10.
41: Cutting through only hurts your F10 group. It was once strong, but now weak after 46.
65: Too slow, just 1 stone.
67: Too slow.
69: Too slow.
71: Too slow. Your group is safe.
78: Consider P5, a move that splits O3 and R6.
85: Too slow.
90: It's safe.
93: Nope this move is better. I think L4 looks even better though.
103: Too slow, is one stone really that valuable?
109: Too greedy, yes you should have left them alone.
115: Too slow. Because White played very badly after you extracted the group from the jaws of death, you have a chance to bully White (sealing White and forcing him to make two eyes on the left is a good thing). However this move is too clunky. K8 looks better.
127: C5 >>>>> C4. B4 punishes C4 appropriately.
137: This forces White to save J8. You could J7 and kill it.
139: Too slow.
141: Too slow, it's already connected so what's the point? It just forces White to strengthen.
143: Too slow.
147: Too slow.
149: Too slow, your group doesn't just have two eyes, it has territory on the left.
151: Too slow.
167: Very bad endgame, just connect at P18, which allows for R19 in the future.
187: Too slow.

Okay I'll stop here. I was about to post overall things you could improve on in this game, but looking at my comments I think it's pretty clear what your weakness was in this game.

was move 158. Then Black captured one stone at "a". was better. OC, if White protects his five stones instead of capturing one stone with , Black will capture at "b", threatening to ruin White's territory.

[Bill Spight]

Another candidate is move 177.

Surprised you only found 2!
