This is the first time i've played with the villain, we've been playing about 20 hands HU. He seems ok and kinda tight. He called two barrels before oop in a dry pot with mid pair.

Here is a very relevant hand i played with him 10 hands earlier. After the hand i realized i probably should've c/f the river.

Obviously, he had a J or a 6 here most of the time, J more often than not.

Now the hand in question. I usually don't try to make thin call downs like this early. But i think that this previous hand shed light on some of his tendencies:

1. He probably likes to slowplay hands when the pot is dry.
2. He probably doesn't raise TP on a dry flop in a 3-bet pot.

Obviously, these are probably's. Is this enough info to make this call down?
