hand 1 i think is kind of close because some regs at 25-50nl 6m are just mindlessly aggressive. but i think his large river size is more indicative of a strong hand than a triple-bluff with KTs or whatever. that said i probably can't fold this in play.

hand 2 i like a shove. he'll call with any J or Q and i'm actually slightly inclined to discount Tx (except JT/QT) when he doesn't min-raise you on the flop or turn.

hand 3 i'm firing because fish don't fold overcards to one bet and so we get better aces and other air with equity (of which there are heaps of hand combinations) to fold. i've been 2-barreling fish a heap lately with relatively high (yet potentially results-oriented) success simply because they can't fold two overcards to a single bet on the flop. leaving turn ranges full of air etc etc
