Derren Brown beats 9 chess players simultaneously.

This is the same way how a lot of people (and I sometimes) cheat on online correspondence chess through a chess engine

One thing tho -- how the hell did he beat that untitled player? that must mean he is a really good chess player anyhow

meh. The players were probably paid to go along with this. They clearly weren't fooled by Derren's silly trick.

pulling that off is an amazing feat

This is brilliant. I'm gonna try this some time.

good luck getting even one grandmaster

Derren tries to pass himself off as good in chess by telling a half truth, the best sort of lie. Notice that each player played multiple games and not just one game against derren. It is more probable that the 9th player was also paired off against the other GM players in most of the multiple games. He just have to play one person in each round and can choose to lose to those players who are behind.

Normally when you play simultaneous games you're White on all the tables, so this trick wouldn't normally work.

Genius :D

amazing

I kinda get how he did the numbers..

notice how there are 2 tens, 2 11's, 2 7's (the one he messed up)

There's something he studied about their first move in order to guess them numbers. and then the draws resulted in a plus 1 and minus 1 because of the mirror he plays. which explains the 6 and 8.

The way he guessed the last one is where the trick is. He knew the number as a result and simply wrote it on the board then thats when he slipped the 5 in with the --"if you just take that there"--
