I play the 5s on PS a lot. The 5s are so full of fish/new players who overvalue sooooo many hands. ...Its tough early w/unknown players. I.E. Is this a GOOD player? or your standardh $5 player? If its your standard $5 player you have the best hand WAY more often than you don't. To a GOOD player I might fold to the flop raise...or else call, check the turn and fold to a significant bet or an obvious value bet.

Judging from your tone you probably lost...to... I'm gonna guess A7. My second guess would be A9. A common $5 player on PS would almost never not raise with 77, plus why raise the SB in that spot with the set? String 'em along.

I'd expect to see your opponent with A9-AJ MOST of the time. Enough of the time to make this play VERY profitable in the long run - though you'll lose it sometimes for sure.
