Hey guys need some help with this hand.

Player at the button is fish with 50/10 stats that's why I opted to 3bet.

Villain (UTG+1) is a good winning reg with stats 30/25. Fold to 3bet is around 50%.

Flop can be played differently but my main question is river action. I'm really not sure what the best action is. Seems a bit weak to skip a river bet and don't charge his pairs 7x,88,99,tt,JJ, QQ?,KK? (even with the 3 flush river).
If we decide to bet it's a clear bet/fold even with 100bb stack?

I only have 700 hands on him (altought I can see via PTR he is a long time winner at this network 5-10 and higher).
