Hi, I recently played a game as white, and black approached my sansan point like that :

I suppose the crosscut at is the right answer, but I'm not 100% sure so that would be great if someone can tell me if this was the proper answer or not...

The whole game is here, I did really big mistakes at the end (and certainly before the end too )... especialy that 210 which should be at 211...
anyway... what I'm the most interested in that game is that sansan "hane" at .

Hane is overplay, cut is good, and game result is great for you (though b14 could be c13 for even better mocking of black's absurdity). But after 25 it would be better to just tenuki: the moves you played there actually helped black and didn't help you much, he ended up getting a respectable position out of a farce. And black left 2 cutting points there that were both fun for you, but in the endgame you played only e18 which was very kind to black to help him fix his cuts.

This is me fooling with the sgf at around move 26 because it looked crude to me.

F17 could be a new move to consider locally if you want to capture the cutting stone?
