BB: 352 (11.7 bb)
Hero (SB): 648 (21.6 bb)

Preflop: Hero is SB with 4 9
Hero raises to 60, BB calls 30

Flop: (120) 9 Q A (2 players)
BB checks, Hero bets 50, BB raises to 292 and is all-in, Hero folds

I think this is a bad fold here: I believe even the biggest fish is capable to push their Ax hands all in preflop so I'll face low-mid pairs or some OESDs/gutshots here. therefore, I have to call since because we need 34% to call. But I could be wrong and I'll face much more ace-x hands than I guess. What is your experience here?
