There are so many possibilities that i can't really answer this, anyone have experience in this kind of positions? I gave emphasis to S18 and Q18 responses but i can't get a conclusion.

Lordish, it's helpful to use a diagram or SGF:

when i attach the SGF file and i copy the location i get the invalid game data msg, no idea why. I am not getting the right link probably, is this a browser problem?

Hi Lordish, I prefer to embed the SGF directly in the post, instead of as an attachment.
It should not be a browser problem.

Block at T18 and play S19 after B connects. There are variations in which you may have to give up the two stones to the left, but the corner stones will live.

Yeah thank you DrStraw, i saw the T18 lines that you have to give up the two stones but i regarded them as very bad for white and stopped, i think that it is better to play O18 instead
of N17 and live in gote unless you need the sente for something very big.

But what if instead of connect at T16, B plays S19 himself ?

Connect at P17 and read this page as one general solution that will help in more than this specific case.
