1/2 NL Euros at B2B (6 max)

MP raises to 6.25E. I call in the SB with 88. We have full stacks.

Pot 14.50E. Flop [2d][8s]. I was about to lead but didnt want him to fold if he didnt have an ace so I checked. He bets 11E. I call

Pot 36.50E. Turn . Well, I screwed this one up. I check. He bets 26E. I raise to 60E and he instacalls. He didnt take any time to contemplate raising or folding so Im sure he doesnt have the flush. In fact, Im pretty sure he has AK / AQ probably with the big .

Pot 156.50E. River . My curser is already on the slider because Im instapushing any non river, which is exactly what I do. Thoughts?

LOL I would be scared of the flush thoi if I was him
