hand 1
at best you'r flipping after the min 4-bet. Call or fold.

hand 2
range is wide. I dunno, his range is 22-AA/AK/some random stuff. On the flop he's narrowing his range to 55+ (sets, overpairs, gutshots). That turn makes for a check-call. If you're going to call the raise then you should shove cos it leaves you about nothing behind anyway.

hand 3
pre-flop good. Flop good. Turn is meh I dunno bet or check behind. I probably bet in 6-max. River easy fold.

hand 4
ahhh, sets out of position. I don't like the flop c-r, hell I prefer c-c and c-bomb turn. As played river check-call or check-shove.
