Opposite of dry-passing, refers to the act of playing deeper into a round with the intent of stripping your opponent of one (or more) of their power plays (win conditions) or otherwise, with the intent of simply shortening the following rounds so that certain cards on the opposing side play for less value. Be advised however that this strategy takes practice to master and can backfire extremely hard if done without moderation.
The strategy is usually employed in the second round by the player who has won the first round, but it can refer to playing deep into the first round with the intention of blocking your opponent from bleeding you in the second round. Moreover, bleeding can occur in Round 1, in which case it means playing as deep as possible into the round while maintaining reach, potentially trading-up with the opponent and forcing out their gold cards. This can be especially effective if you know that their game plan relies on winning the first round.
Example: Assume you are playing against a deck that you know has two significant win conditions. You managed to win the first round, but you know that you cannot win another round unless you strip the opponent off of at least one of their win conditions. Therefore, you play into the second round with the intention of forcing your opponent to commit one of their power plays, weakening their following round significantly so that you have a way better shot at winning the game.
