might be one of my patented enormous blunders - but I think it lets white off too easy. You are ao string in the area - you should just cut off his escape and crush the little white worm. The move you played leaves behind a big cut that white could exploit laterAgain this could be a complete misread on my part:

at S15 seems fine to me, isn't it?
white just played a move to try and reduce black a bit, because black has a huge moyo. Black does want to capture the one stone that black goes after in the game, but capturing it like this is small. It'd be better to play something like K8, threatening to make a huge amount of territory on the bottom, challenging white's stone on tengen, and also building influence to kill off G3 naturally. If white tries to run with G3 after, the stone at K8 helps cut it off from a lot of its possible support, and black should be able to consolidate the rest of the moyo by attacking it.
. Black can always play the 1-2 point to live, and it feels very passive, as white shouldn't care about that one stone.
