Just an unlucky hand against a player with no respect for the game. I have never minded losing a tournament, whether to a good hand, or a bad hand with the chips and a 30% chance who you know has thought it through and decided at that stage of the game the gamble was worth it. I hate losing to a hand where the donk has no thought about the risk, the stage of tourney or, god forbid...his ongoing table rep (which is an actual weapon when playing live in decent stakes). The lack of respect for the game is what pisses me off in those situations, not the loss. I would much rather walk in the door, stake a player who REALLY wants to learn and earn, and walk away from the table wishing him good luck than lose to a no respect Joker.
Sorry you're having a bad run, but they happen to all of us......you can only hope that when losing, the money goes to a Poker player and not a Bingo hound!!!
