This week we’re focused on a cash game spot where you are out of position against a tough player in first position (UTG) after 3-betting their open raise from 3BBs to 12BBs from the Big Blind.
Since you are making a large, out of position raise from the Big Blind versus an already narrow Under The Gun range, your range is going to be both very narrow and polarized. The defending range for UTG in this scenario includes many strong hands, even calling AA/KK a significant portion of the time. This means postflop, that while you as the Big Blind often have top end range advantage (also often called nut advantage), the overall range advantage on many flops is actually with the UTG player.
