Many poker players like to make this analogy. While some of these players seem to actually be chess players, they don't seem to understand how chess actually works.
Here are some quotes from the article.
"The purest example of a game with no variance is chess."
This is simply false. In fact, the formula that calculates a chess player's rating is more or less the very definition of variance. In a typical chess game, you are playing a player with a rating within 100 points of yours. If you're playing someone 50 points below you, you have a 35% chance of winning and 21% chance of losing (the rest is chance of a tie.) At 100 points, it goes to 46% and 18%. (The draw percentages are actually a little misleading, since games among lower rated players end in draws much less often than games among higher rated players.) In fact, meeting certain percentages is how your rating is determined. In other words, the entire rating system is based on variance. It's not more unlikely that you lose 3 games in a row against an equally skilled player than it is that you flip 3 heads in a row (not accounting for ties.)
"If you played Gary Kasparov and you were not an international grandmaster, it would be next to impossible for you to win unless he made an uncharacteristically large blunder."
Well, yeah. This is about as interesting as saying "If you flop the bottom end of a straight flush in Holdem, it would be next to impossible for you to lose. There is basically no luck and no variance in the game." In that scenario, true. But how realistic is that scenario? How much of your actual playing time does that scenario represent? How many players that are not international grandmasters has Kasparov even played in the last 20 years?
"There is basically no luck in the game."
This is another misconception. Just because chess is a game of complete information, it doesn't mean that the players can actually employ that information. Theoretically, it can be done. However no human or computer has accomplished that feat.
Until everyone can, chess will remain a game with luck, variance, and yes... even bluffing.
