HAND 1

Preflop: Hero is BB with QQ
UTG(800) limps, SB(150) limps, Hero(710) raises to 35, both call.

Flop: JT8
SB shoves 115. Villian 1 quickly motions as if he is about to fold out of turn. Hero shoves 675. Villian 1 quickly pulls back cards and goes into tank before calling.

Most people I have talked to said this was a terrible shove but I believe I extract maximum value from all draws as I expect to get called by something like A3.

HAND 2

Preflop: Hero is BB with QQ
BTN(600) straddles. Hero(1200) raises to 35. UTG+1(600) calls. CO(750) calls.

Flop(105): 985
Hero bets 55. UTG+1 folds. CO calls.

Turn(215): 5
Hero bets 90. CO raises to 290. Hero tanks for 3min+ before shoving.

My sizing on flop/turn is usually much larger and I really have no excuse for why I didn't do this. While I was tanking in this hand I started talking to villain and although I was ignored at first he eventually started to become very talkative. When I asked why he bet so much he said he knew I had a big pair and just wanted to take it down now. Deep into the tank I started shuffling my greens and he said "good call", which I perceived to be an honest mistake rather than an angle shoot. This is what finally helped me come to the decision that he had a monster draw rather than a made hand.

Hand 1 is a spew. You don't necessarily extract maximum value from draws because you are getting it in on the flop when their equity is greatest. If you make them pay on the turn with only 1 card to come their equity is cut roughly in half, and most bad players still can't fold the draw on the turn. Also, if he really does fold like he's showing, your call and raise are the same. If he's angle shooting you just played right into it by shoving. I call and probably fold if he shoves. If he calls I'm looking to bet big on a good turn card.

Hand 2 without reads is a standard baluga fold. Your weak bet may have induced a bluff and you seem to know that, but even still I think I normally fold here. It sounds like you had a good read though and knew to re-pop him which is fine.
