not to sound like captain obvious, but the main determinant for whether i'm going to 3b here or not is whether or not i think he's going to continue with dominated hands.

there are a lot of regs (especially at FR) who wouldn't continue with AQ- when facing a 3b to their MP open, and it's not even all that uncommon that i think that a 6m opener OTB isn't calling enough to justify 3b'ing.

of course it's 10nl, so sans reads, i'm just assuming that they don't know how to fold pretty hands, so i'm exploiting that by value 3b'ing them with AK
