Jesus christ you played too timidly in my opinion.
hand 1: i'd bet more on the flop , c/c on the turn and bet 2/3 pot on the river.
how the hell you folded your trip kings when he shoved over your weak tiny bet???Also, i think you have bet sizing problem.

hand 2: i definitely call on the turn and reevaluate on the river. If the board is not paired and he still bets huge, i'd consider a fold at that point.
how the hell you folded one overbet on the turn?
