all in or stop and go?

[Lloyd]

A perfect application of the stop and go is a pair versus overcards. If you push, he'll call and see five cards. If you stop and go and he misses, he'll fold and only see three cards. So you're more likely to win the pot by utilizing a stop and go, even if the pot is slightly smaller. Add in some possibility of him having a slightly bigger pair (like JJ) and folding to a scary board and it's an even better spot.
