Hand 1: I'm checking this one. It might get checked thru and I'm not sure a semi-bluff works at this level because they will call if they hold at least 1 broadway card in the hole.

Hand 2: I probably check this one also. With 2 broadways and 2 flush cards showing, I doubt you take this one down right there. I check, hoping to get a free card.

Hand 3: I'm betting this one. I think most diamond draws would have stabbed at this flop. It's unlikely that this flop hit anyone, so as long as nobody has the King (which they won't most of the time), I think you'll pick up the pot. Plus, you have 6 additional outs against someone holding 6x/4x/2x.
