If we think he's 3 betting pre with QQ+ then it becomes pretty close because over pairs are obviously the hands we beat. His hand is really weighted to sets, 2 pairs and pairs + OESD. Against 67s - 9Ts plus 66-TT we're 40% and need 43% to call. If we can add JJ to his range, we're 46% and it's a call. Adding QQ and KK make it a much easier call.
In game I'm calling.
