hand 1: bet/fold flop is standard. clearly the turn/river cards were among the best possible and you still really only beat a bluff when you call the river.

hand 2: really opponent dependent what to do on the turn. how often he floats or his folding frequency with KT/QJ need to be considered to make a turn/river plan. we only have 8 outs on the turn so check/folding isn't terrible. we don't have a lot of fold equity in this situation.

hand 3: yea don't flat this hand versus MP. i prefer folding since we are 50NL competent (i also play 50NL).
