PreFlop - I'm not a big fan of 3betting preflop. For me its a solid hand to call due to the multiple limpers. On the flop you will very likely be looking at a board with no trips (for you) and at least one overcard. You'd be forced to slow down and I think you will need to followup the preflop 3bet with some aggression. However, 88 usually will not be so attractive after the flop.

Flop I'm out - based on the opponents preflop raise and the willingness of the 2 others to call the bet on the flop makes an overpair very likely.

Turn As played - I'm out to the bet. You're drawing to 2 outs - 1 to 22 and the pot is 1 to 8ish
