Jimmy "Gobboboy" Fricke has issued a fierce criticism of the renowned Bellagio Casino in Las Vegas, home of some of the biggest tournaments and cash games on the planet.

Fricke, who has a runner-up finish in the 2007 Aussie Millions Main Event worth $795,279 as his biggest result to date, launched the verbal attack today via his Twitter account, claiming that the decks used in the casino are marked.

Moreover, Fricke also claimed that the faulty cards is a well-known issue among regulars, but that no one seems to care about it at all.

"Every single ace of spades is marked at Bellagio and no one gives a shit at all. I've pointed it out in $10ks (tournaments) and in big cash games and no one cares," Fricke writes, continuing his rant by saying that the marking appears as a result of the way the cards are stored.

"They are all warped because of the way they are stored," he adds.

The colorful American pro also admitted to have taken advantage of the marked aces himself, by confessing that he on one occasion used the information to pull off a bluff he otherwise would never have been able to make.

"Screw this. I get into a pot where I know my opponent has the ace of spades after I've told the table they're all marked. I feel like a cheater," Fricke writes.

"I pulled off a bluff in a spot I'd never try it," he adds.

It isn't the first time controversy occurs over supposedly marked cards in Las Vegas, and especially during the WSOP at the neighboring Rio Casino, faulty decks have been a reappearing issue.

This was also the case during this summer's WSOP, where several decks had to be replaced as they were either marked or missing cards altogether.
