That's one reason to not fold a 220 pot to a 20 bet. If he really has an ace, you've got two outs, which isn't worth much. But, again, a minbet? Either he has a very weak ace, or he's trapping. Minbetting a draw seems like a foolish play to me.

I have found that bluffing works often enough at low-limit SNGs, especially after raising 3-5x preflop. Everyone thinks I have AK or AA or KK, and I've won a ton of pots on the flop by betting out against an A-high flop. If it gets to the turn, another bet can win it. And if I get reraised all-in, it's an easy fold. (At least, that's what I've been doing after reading some of the masters post on good NL play.)
