PLAY AGGRESSIVELY, it's the winning way
There's a very well known Poker player, a man who enters the World Series of Poker every year, who has a talent for figuring out exactly what your hand is. But when he decides that you're holding a Pair of Jacks (in Hold 'em) and his own hand will not beat the Jacks, he'll try to make you throw your hand away.
To me, that's not being aggressive ... that's being stupid. It works sometimes, but should you jeopardize your money when you think your opponent's got a good hand? Let him win the pot and wait till you think he doesn't have much of anything. That's when you can try to bluff him out of the pot. Or wait until you think you have him beat.
Everybody in Poker thinks he knows what a tight player is, but I'm going to define it again because so many people confuse the term "tight" with "solid".
"Tight" means conservative. A tight player is a player that is tight pretty much all the time.
