BB is a reg, SB is an unknown I have 13 hands on him where he is playing 38/38.

I'm not too sure what to make of these small reraises. Does anyone believe it's worthwhile reraising to isolate the probable recreation player in the SB or is a call standard?

SB elects to lead small after the continuation. With two backdoor flush draws, a blocker to the nut straight and an oesd I elect to raise hoping to win the hand here. Villain calls. As the button I feel my range here is wider and thus this low connected flop is better for my range especially with the small reraise.

On the turn I make top two pair and villain checks to me once more. I'm torn between betting for protection/ get value from any wraps like 789x. There is a chance villain flopped the nuts and was waiting for a safe turn to check-raise. When villain calls I think it's safe to say he doesn't have the nut straight however he may have some combinations of 24 maybe with a large pair like KK or AA. Alternatively, he could hold a similar hand to me with nut spades and a 4. Or a two pair hand that has made a set on the flop and is waiting for the board to pair.

The river is the Ad. Whilst I think it's definitely possible that I have the best hand some portion of the time, when villain checks the river I feel as though he can have some A high two pairs that beat me or his sets and I elect to jam. My line is extremely nutted and I expect villain to fold for what it almost a 100bb river bet.
