I fold hand one preflop a massive % of the time. As played its fine i think, even if he's valuetowning QQ on the river, you obviously don't beat that. I suppose a donkbet could be in order on the flop, but he might own you with any two cards if you do that, so I'd rather check.

Hand two is terrible IMO. I like the flop check probably 50-75% of the tme. Bet the turn, bet the river. As played call the river instantly. You have top pair good kicker underrepped in a threebet pot with position.
