The Yeti Theorem
This theory was created by a long-time 2+2 poster. It stats: A player who 3-bets on a dry, paired board is [almost] always bluffing.
A perfect example of this is: Say you're on the BB with 99 and its folded to the button who raises it up. You call and the flop is 6h 2d 2s. You check, your opponent bets, and then you check raise him. Now if your opponent re-raises you, this is where the Yeti Theorem comes into play.
If your opponent had a 2 or 66, they would not 3 bet on this flop. Instead, they would be more apt to just calling your reraise in hopes of profiting on the later streets.
