Not only would he have to call the raise with low pockets, he would have to have opened the pot for a 2xBB raise with that same hand. Does that sound like 22 to you? In a cash game, in middle position? Not to me. 77 or 99 is plausible, but I just don't know if he plays it that way on the flop. I'm not saying he wouldn't, but I also think he'd do the exact same thing with tens, jacks, queens, maybe even A9. There's so many hands he could play that way that you're ahead of. I think I'm pushing.
