I think dead.

Calvin (AGA 11k): I think white is dead. W1 seems natural, but after the hane of B2, a and b look to be miai. If W1 at a, then B2 at W1.

And now?

Rich: It's a well-known problem (I believe it's in Kageyama's Fundamentals of Go) - but for the DDKs, what's black's tesuji response to 3?

Maybe this throw-in?

Walin: Looks like B4 would kill white after W3.

with help, try to connect

Calvin: If white has a helping stone at white+circle, maybe this invasion can threaten to connect out like this. This appears in a few pro games. (Note B2 is different here.) Without some external help, I don't know what to make of W1, unless it's a ko threat. Is W1 a reasonable move?
