in hand four it was spot I felt it would be profitable.

In hand 5 I was thinking "great hit the straight." then on the turn I was thinking the flush was there, so I bet to call, then check call the river. The flat call made me reconsider whether I was still good. What do you all make of villain's check on the river??? what hands do you now put him on?

Hand 6 I am always bet/raising OESDs, 4betting rainbow flops like this. On the turn I check because I was thinking that any ace or 9 might fill them up. King on the river was a quedstionable spot for me. Wanted to bet for value (is there any value) but it filled other draws

Hand 7 Villain is a tight played, definitely put them on an over pair pre-flop, thus the call. On the flop I think I am good, but have to question it with V 4betting (perhaps 99, more likely just over pair). The turn throws me off a little. I am willing to three bet my set, what hands just call the three bet? Could it be 99 worried that the draw came thru (I have shown that I will bet my draws hard)? Could villain be calling for deception in order to extract more bets on the river? RIer hits, and I am done with the hand, but is there value in betting there (bet/folding to a raise, maybe for fold equity)?

Hand 8 I feel is standard, any turn checks here?
