I'm finding that all the tourneys I play in, there is more pre-flop raising than there used to be. After all, players, even at the $1.10 buy-in level all know that if you're going to play a hand, you're better off raising with it than limping. But if everyone at the table knows this, then is there any value in going against the grain and limping with a playable hand, then after it gets raised, go ahead and re-raise? Does anyone do this? Is it a good weapon to use?
