This is an on-going game. Probably not interesting to anyone other than the current players.

And white will, eventually, have to play at a, but that can wait to respond to black playing J16 (or white J16, black K17)

While those moves don't seem to cost black anything, b/c white has to respond and they don't have any direct implications elsewhere on the board, they are needlessly giving up ko threats.

Yeah, white is alive.

At first glance, I would be tempted to play L3 :

This is painful for white compared to

Now the question is : while this seems good localy, is it the best move globaly?

Is this a 6-stone handycap game?

I would have played the same as Tryss, on first instinct, however it can get a bit tricky:

Thus, the cut may enable white to cause some confusion and establish a group in black's moyo - I can not read all relevant variations, here.

Maybe a much simpler way (That's what I always tend to miss in a real game ...):

improves the connectivity of b's lower stones and still threatens to push through at L3 in one of the next moves. When white fixes that, :b3:

claims a huge territory which seems rather difficult to invade. Black also has most of top right corner and good potential at left side --> w will need doing something spectactular tu turn this.
