By A judge upped the ante today for an online poker kingpin’s freedom.

Ray Bitar — CEO of the Full Tilt Poker Web site — was ordered to post $2 million in cash or property to secure his $2.5 million bond, up from $1 million set last week.

Manhattan federal Judge Paul Engelmayer noted that Bitar “has one million reasons to return to court.”

The FBI busted Bitar last week at Kennedy Airport after he returned from Ireland to face charges filed against him last year as part of a massive crackdown on Internet gambling.

Offcials shut down American access to the biggest three poker Web sites — including Full Tilt — on a day that online gamblers have since dubbed “Black Friday.”

Bitar is accused of defrauding bettors out of more than $430 million by falsely promising that their money would be kept in “segregated accounts.”

He allegedly pocketed more than $40 million through the scam, which prosecutors called “little more than a Ponzi scheme.”

Following his arrest, Bitar said: “I will continue to do whatever is required to get the players repaid, and I hope that it will happen soon.”
