No it’s that some that consider themselves “smart gamblers” when in fact they’re just like casinos, they won’t play without an “edge”. Take their position on card counters. Card counters take away their “edge”, evening up the game. In the mob days in Vegas that could end up with you in the basement being offered to leave without your winnings or get worked. Then came multiple deck shoes, the Black Book, all to stop anyone intelligent enough to take away their edge. Casinos aren’t gamblers, they’re in business.
Pool players that won’t play an even game aren’t gamblers or “smart gamblers”, they’re in business. Now if someone comes barking at you offering too much weight or not asking for enough, then you’re almost obligated to take them off, they asked for it. But to never offer an even game or never take an offered game that is even means you’re not there to “gamble”, you’re there to do business, a nitty lock artist. The definition of gambling is “to take a chance”.
A “smart gambler” is a person that is smart enough to know how to truly clock an opponents game and is honest with themselves of what their own speed is to make an even game, and the heart to get in the box and “gamble”. May the best man win.
