We are at 400/800 ante 100 and i am on the bu with ako after à min open from an italian Guy, he is playing about 30k and i am covering him, we don t have much history other than i squeezed all in 22 and won the flip against his mp ako flat and after that he quite the table 10 minutes before diner break so he might be a little upset against me' he is playing a lot of hands (too Many) and don t seems to be à good poker player , i 3b to 4k and he cals as expected and the flop came qqc7c  and i don t have any club, i chose to check back and the turn is the 9c' he bets rater quickly 8,2k ans i decided to cal after thinking about it a few secunds.

The river came the ah and hé almost snap bet almost all of his chips bottine 19,5 k .

What do we do given the fact that this should not be a river he is wiling too bluff.
