Yeesh, think some peeps are being a bit harsh on the OP, here... Although I'm saying this because I ASSUME s/he was joking about wanting those players banned - to me, that comment seemed like just a bit of hyperbole to express the frustration of losing hands to players who call with draws when they're given TERRIBLE odds to call, but then get lucky, beat the odds and make their winning hand.
Most of us know those players are profitable for us in the long-run, but it doesn't stop it being irritating on occasions when they do suck out - especially if (for example) it costs you your tournament life.
I will say this to you, though, midget: there's a big difference between a villain calling with terrible odds on their draw, and a villain leading out with a big bet when they have poor immediate odds of making their hand. Semi-bluffing with outs can be a very powerful weapon in the card shark's arsenal.
