Hand 1: I would reraise a little more to cut down his implied odds for calling with a small pp. The way played I shove, if you hit a set well ... [censored] happens.

Hand 2: Unless I know villain is some crazy maniac I fold (a Baluga isn`t it ?)

Hand 3: I don`t mind checking behind in position on that flop and 2 players in the hand. The way you played it I just call the turn and hope to hit my spade on the river.
