I'm not a sng player but:
first of all, do you have any stats on villain?
You start the hand with only 27 bb's, so I'm not a big fan of just flatting pre-flop, altho this is opponent dependent, But assuming most 1.50 sng players are pretty bad, I'd just shove pre.
Otf You should know he probably c-bets a very wide range of hands, and only a K or pocket aces has you beat, so I think I might personally consider shoving, but I'm terrible post-flop with short stacks.
So basically; shove or fold pre.
