Hand 1.
Ugh - puke then call and call a river bet. Unless 10nl has become 'i only raise wif set' then you arent folding here...

hand 2.
Dumb - what equity do you have against his range? Also, his hand range is relativly solid on that flop so you want this raise to be more value and semi-bluff than pure bluff.

hand 3
Calling the flop is fine - a Queen doesnt help as much of his range as an A or K does - but when he fires the turn muck. If he checked to you on the turn then you probably bet...
