Hand 1 - I'm betting this turn harder... around 25-30.. That is a bad river card, checking behind here may be the better option but you would lose huge value against weaker hands.

Hand 2 - I would be re-raising preflop here since it is a min-raise. I don't like the flop check either, the pot isn't really big enough fo ryou to be disguising your hand. And if you check and he bets around $2 are you going to c/r? As played I would 3bet to turn around $15 or so... the pot wasn't built at all and you need to start building it.

Hand 3 - I'm ditching this preflop to avoid situations like this. As played I fold very fast here on the flop. I know the read you have on villian but this is how they end up making their money, situations like this.... I just really don't want to get involved in calling down a bluff with TPDK.

Hand 4 - Yeah this hand is kinda screwy by the converter. But as played he has less than 1/2 of a stack and I'm not folding here.
