Hand 3: call flop, see if he double-barrels on turn and play back hard on any spade or K.

Raising the flop here puts us in a bad spot no matter what villain does apart from fold.

If he calls does he have A with weak kicker or does he have flush draw...if he puts presure on us again on the turn we're in the same boat we are now except now a spade leaves us in more doubt and if he raises then we are pot committed due to stack size.

His 1/2 psb on the flop does look weird and like he's looking to 3-bet shove on us here so let's wait for turn and see what develops imo.
