"Nobody likes a bully."
Poker is one of the few contexts in life where being a "bully" is not considered a bad thing. In fact, it's absolutely essential to be able to put the heat on your opponents and to rake pots through intimidation. There's nothing wrong in using the leverage you've earned through your strong play
throughout the tournament to pressure your opponents.
Greg Raymer is one of the most amicable people you'll ever meet at the poker table. But he's a multi-millionaire with a WSOP
Main Event bracelet because he was ruthless as the chip leader. If you're hesitant or embarrassed to play the part of the bully because of what the other folks at the table will think of you, it's time to consider another game of choice. Hearts, canasta, or rummy may be better suited to these genteel sensibilities.
I'm dead serious when I say that if you hang onto this misguided notion, your game will never be all it could be. Not to mention that you're steaming at another player for simply doing what he's supposed to do with a big stack...use it to inflict trauma.
