You have $80 in the pot already before the river so $120 behind. Difficult to make any sort of bet and then fold to a re raise against an unknown opponent (against a very solid player who i've played with a lot I could MAYBE find a fold). With so much money in the pot I also find it hard to imagine him check raising you on the river hardly at all, but obviously can never rule it out

My play would be to assume he has a AcQ/AcT/AcK/AcX/KJc (don't think he would be slow playing a set on this board) type hand so would make a bet of $80 > $100. With I'd also think about running the clock down to just a few seconds, maybe faking a missed draw?
