a group of very tricky players a mix of lag and tag. I'm seen as tag. we've been playing for awhile and they know I'm cabable of making a play. i have 60k while the rest of table has around 50k i have villian covered.

utg raises to 400 folded to me where i decide to make it 1600 with 5h6h in the cutoff. Villian is a tag player and is very very tricky. He thinks and min raises to 3200. I call.

flop: 347 rainbow

Villian leads out for 4000 i think for awhile and call.

turn: ace no flush draw out

Villian bets 9k he has about 30k left. what do you do?

if river is brick and he bets 20k what do you do?
if river pairs board and he still bets 20k what do you do?

advice on all streets would be of help.
