This is a good post about the stop and go. To quote Irieguy, [ QUOTE ]
There are two distinctly different situations in which a stop-n-go rates to be +EV:

1. When your chip count does not leave you enough folding equity to cause a player, good or otherwise, to fold if you come over the top of him preflop. All good players know how to do this.

2. When your opponent is not particularly good, so all you know is that he is more likely to call a big bet preflop than postflop.

I think this is a push. If you had roughly a pot sized bet left for the flop, I'd prefer the stop and go--but here you have around 6bb to work with preflop, and 2.5x pot to use in a stop and go, which seems like too much.
