There are plenty of tournament situations, where its good strategy to open jam or rejam any pair especially in a late position battle. Lets say we are playing a traditional 9 man SnG, where 2 players have busted, so its 7 left. UTG and UTG+1 have 3.000 chips, everyone else still have the starting stack of 1.500 chips. Blinds are 80/40 with a 10 ante. We are sitting in BB with 22, and CO comes in for a min-raise. We are 19BB effective and both players have the same stack.
If we just call here, we are going to massively underrealise our equity postflop, because when we miss our set, we will usually face a C-bet and fold. And when we occationally flop a set, our opponent will often have nothing, so we wont get his full stack, which cuts down on our implied odds.
For those reasons our best play with 22 is to shove our 19BB in his face. In that way we get fold equity, and when he call, we still have a decent chance to win the pot. Sometimes we are going to be a 4:1 dog, but more often we are going to be flipping against two overcards. According to ICMzier jamming 22 wins us 0,52% of the price pool, so its not even close or marginal.
