Hand 1 - I just call the river. I don't see him on KK, but I'd expect to see K-lower kicker roughly 60% of the time, K-high 2 pair maybe 35% of the time and a set 5% of the time.

Hand 2 - I bet the river. He's done nothing to show he has a queen, so I keep firing until he pushes back.

Hand 3 - A non-flush card hits the turn and it's a definite raise. I have a hard time putting him on the flush, though, because it's very unusual to 3-bet a flush draw. Still, with the flush hitting, I don't think it's wrong to just call down. I call the river and expect to see either an AQ or a smaller set.

Hand 4 - My spidey-sense is going wild on this hand, and it's telling me that BB just flopped himself a set.
