SB is tight or loose preflop? I think that matters here. It's possible this could be a 7, but unlikely. Most of the time you are splitting or losing. Hard to say without any sort of read.

that's rough... i dunno what to do here

[YanP]

reload before starting the hand, but push this imo. there are loads more lone 7's than QKs

[Profish2285]

With a 75 bb stack this is a standard push IMO. You will see QK, but you can also see a lone Q which youre free rolling against, possibly even a 7. If villain EVER does this with a set then its even more standard of a call.

[Kasane]

Just push here -- hopefully you're freerolling him rather than the other way around.

reload pf, obviously. You've got like 10bb's left, right?

[ajmargarine]

Agree with the rest, Push it here.
