Here is the situation: you have a below-average stack of approximately 11K (down from a starting stack of 15K; you've missed a couple of big draws early where you have correctly folded to pot-sized bets on the turn). Table is seven-handed; you're in a two-table live tournament with the top-3 places of 13 runners paying out. A proficient LAG who seemingly doesn't blog anymore opens for 3.5 bets in MP. The button calls.
You look down at 99. You decide to squeeze and make a pot-sized raise to 3.5K (putting in a third of your stack). The initial raiser puts you all-in, the button folds, and you have to call your last 7K or so to win a pot of approximately 23K for your tournament life (the SB and button contribute about 1K of dead money, so that means it's your 11K +1K dead + 11K villain). You believe your opponent is only putting in the last raise with bigger pairs or two overcards. This means you have roughly 40% equity against his range in a back-of-envelope calculation, you figure, as you go in the tank at the table. The chief difficulty is how much to weight his range towards the overpairs where you are a 4:1 underdog vs. the classic race situation where you can't get your chips in fast enough given the pot odds.
Do you call or do you fold?
