It's very +EV if you can then figure out when the BB has 2 pair on a flop like 93x without stacking off. Admittedly, against lots of people this is pretty hard. Against the fair share of Party fish who play 2 pair+ in a specific way, though, you can get away cheap. (Also, as you now have a 1 pair hand vs. any two, prepare to check behind and call a lot.)

If you happen to be 'un'lucky enough to wind up with a 6 way pot, it's actually much much easier to do that, though.
