hand 1:

are you trying to rep the K there? did you have him on A or K of clubs? from his perspective, i see you check flop, call a weak raise on the turn, and then all of a sudden you're interested in the hand when the K of spades comes? i feel like he probably called w/ a 10 or something to take it down. i don't see that being a good bet very often. maybe you saw something in his patterns of respect that gave you an edge.

hand2: you probably won this pot, but i think you called his all in while behind. i don't have a problem if he lead out there and then YOU pushed over the top of HIM, because you did have several outs, presumably. but to call that seems like you're behind most of the time. switch seats w/ him and it's fine. you might be able to call if you also had an OESD in addtion to the flush and paired board, but even then you'd still be behind for the money.
