Now this guy has been very quiet preflop, limping and folding lots of hands, folding most of his limps to my raises, but calling a decent amount of my raises.

Preflop: K6s is a decent hand headsup

Flop: I know he's been betting minimum at most pots when I checked it to him, so I figured I could throw in a check raise with top pair + flush draw.

The turn: I should've bet here, but I don't know why. I checked just because the ace scared the [censored] out of me and I put him on the ace when he checked

The river: A stupid bet just to see if I could buy the pot here or have him call and see if I won. I don't know why I bet or what else I should've done, I figured checking would lose me the pot anyways.
