eww sux that SB is deepish as well.

With no read on SB I make it 85ish here and fold to a push from SB. Most of the time though you have the best hand here based on description of light 3-better.

If you think you have an edge postflop there's nothing wrong with flat-calling

Grossest situation would be for you to pop to 85ish then gasp in horror as both villains call.

pushing could actually be a very sexy line here when it comes back to you. If you figure SB has AA/KK almost never then you might get a hilarious call AI preflop from 1010/JJ...

edit : just read your SB read and based on that I think not repopping here is criminal. Also I think pushing is awesome since it's soooo unlikely you're up against AA/KK. But that might just be crazy talk...
