hand 1 - fine

hand 2 - also fine

hand 3 - i'm probably raising the turn there, a jack would normally check/raise. i don't mind overcalling the river either though.

hand 4 - yeah

hand 5 - fine, if it was HU i'd probably bet the turn

hand 6 - not good, either bet the turn/fold to a raise or call that river

hand 7 - also fine, overcalling the river sucks.

hand 8 - i dunno, i might look up that river gaybet. that's a draw heavy board and people love to take shots on scare cards. folding is probably fine though.

all in all, i don't think they're that bad. only one i really take issue with is hand 6.
