I cannot seem to find this position on the wiki with Black to play. Can Black kill, or at least force a ko for life?

Inside hane looks strongest, although blocking to the right of W2 may be slightly better than with the normal W2 in a tewari analysis.

fractic: Black can make a ko like so:

The W2-B3 exchange doesn't really change much.

The inside hane is not a good idea and white can live easily.

If B7 stands up (point to right of B7), W lives uncomfortably, in ko. The ko doesn't carry the large burden normally required of Black in this starting position.

Ah you're right. But black has some nasty aji in that shape. Especially if white plays W6 before W4.

For some reason this is very common in games I play, and I have this sinking suspicion that when white lives it's because black makes a mistake...

This would be still ko, and better for Black than the normal ko
