Thanks for the replies everyone!

For the results oriented, in the first hand villain had pocket 9's. He thought for his entire time on the turn and called with 1 second left. I think Bdawg may be right, that a bigger bet could have taken it down.

Since villain took the whole time before calling on the turn, does this change our action on the river? More or less likely to fire again?

Second hand, villain had A8hearts. I suppose my thought of check calling was being results oriented. Villain may very well have bet if turn was a blank with his flush draw, and more often than not he will still be drawing. So check-push seems like it could be good in this spot. Though obviously in this hand, I would have stacked off had I pushed (though.. I stacked off anyhow lol)
