Hand 1:

.30-.50 on turn to build the pot. Give him pot odds to hit his flush, don't bet much more than half the pot, but bet something! If he has a 6 he might go AI right there.

The check isnt all that bad either. It let the guy hit his flush on the river. As played go ahead and all-in river, he likes his hand.

Hand 2:

This guy likes his hand as well. If he's a passive player a minraise could mean a monster. Just call the min raise and reevaluate turn.
