hand 1: I hate checking this flop, cause you can't rep anything on the turn, except maybe for 89s. Also, calling the river bet is awful, since he can easily have any pp, and you look kinda dumb when he flashes 22 and ship the pot. So you gotta raise somewhere, or just give up.

hand 2: If I check the flop and call the turn bet, I snapcall the river as well, otherwise checking the flop is really really bad. Don't go into the deep leveling stuff, maybe he's already forgot the prev. hand and doesn't remember your name, and given the fact that he's calling raises from the SB with trash like QT, his range is quite wide here.
