posetcay:
Looks like you already corrected it.

posetcay:
Both of them are accepted answers.

caranthir:
They are both marked as correct, ie. good enough. Not it this particular situation, but in a general setting I think ogeima leaves (after cutting at 1st line, N1 lower right, or M2 - M1 - N1) some sente-ish moves for the defender which can lead to lack of liberties to the outside group, but also possible ko for the benefit of attacker if they have threats. Looking at just the local points here, ogeima is better.
