My favorite story of the weekend.

The cheating chess grandmaster in the Dubai Open tournament.

Cheating how? Rigging the clock to give him extra time? Telling his opponent, “Hey, is that Bobby Fischer behind you?” and then swapping pieces?

No. It’s better than that.

Gaioz Nigalidze of Georgia (the country) cheated by hiding a smartphone in a toilet at the Dubai Chess and Culture Club, where the Dubai Open was being played, and by taking lots and lots of bathroom breaks.

What he would do is go into the restroom, and to the second stall from the left, retrieve his phone from behind the toilet and go to the computerized chess application he left open, and get the machine to tell him his next move.

How was he caught?

His opponent from Armenia alerted tournament officials to Nigalidze’s odd behavior, which included all those bathroom breaks at a crucial part of the game.

Why would he try to cheat? Because first place pays $12,000, which is real money in Georgia. The country.

When confronted, he denied the phone was his, but tournament officials found another screen opened to his Facebook page. Oops.

And Nigalidze was tossed from the tournament.

We have a photo of the cheatin’ chess master, and he is looking at the camera suspiciously, as if he expects someone is taking his booking mugshot.

Cheating in chess seems wrong. And at first thought it seems difficult, but it has gone on for some time, and especially of late, because if you can get some help from a computer (and remember when — way, way back in 1996 — when grandmaster Garry Kasparov defeated an IBM computer named “Deep Blue”, demonstrating human superiority over the machine? That is so 20th century) you are going to win.

And with money at stake …

Anyway, the toilet bit is what made it memorable. Right up the road in Dubai.
