Hand 1: I didn't really want to check raise since there weren't really any draws besides 45 (which of course got there on the turn). I think a check-raise on the turn is really ugly for the fact that I could see a showdown for the same price as check/calling the turn+river as well as inducing a lot of worse hands to play back at me. The other alternative is leading the turn, which I think in this case is the best play, since I don't think he sticks around with a one pair hand with a second barrell on the turn I could safely check/fold the river or check/call a small bet. I did end up calling due to the fact that I had played it very tricky and may have induced a bluff, and I was getting about 3.5-1 which means I don't have to be right very often to make it a good call. Unfortunately, he flipped up pocket eights for rivered quads.

Hand 2, with my read on this player I just mucked, the Q was a scary turn card but not really, he wasn't the type of player who would cold call a raise and a reraise with KQ or AJ (not to mention calling the flop with a gutshot). I put him exactly on TTT or KKK, with a small chance of AK. So I think I made the correct laydown.

Hand 3: I figured he would have AK a large portion of the time with his big reraise, and that the dead money would make up for the occasions when he had a bigger pair. So I pushed, he called with AK and not that it matters but I lost the race.
