I just thought this was such a pretty online game. multiple ladder breakers and makers in different directions and squeezes.

I was kind of surprised to see this inside hane trick play wheeled out by black so many times. Is there really no way to better punish this in a 4 stone handicap game?

Nice to see you back dhu.

Java, the usual resistance/punishment of extend out requires a favourable ladder (with this standard ladder-building technique you might recognise from 4-4, approach, one-space low pincer, jump out, press, push and cut variation), which obviously white won't have in a handi game:

Also, given Golaxy's fondness for allowing the 2nd line gote seal (by answering inside cut at marked rather than resisting with a) in this similar but shifted along a line 3-3 invasion joseki (e.g. http://www.go4go.net/go/games/sgfview/74252) I wonder if white isn't quite as bad as we think.
