A2o in BB early on

[Conor]

Party $200+15. Wild table, four knockouts in the first 15 hands. The only action I've seen from SB is a preflop reraise all-in with AKo.

I expect betting the flop is the standard line, but I chose to risk a bum turn and wait for the raise opportunity. How's the river value bet on the flush board? Anyone fold to that check-raise?

I generally bet flop here. Too many annoying cards can come off for me to use this hand as a bluff catcher.
Folding the river is reasonable too. Unless they are insane or a genius, you are dead.
