The woman who helped Phil Ivey win $12m from Crockfords casino in London and $9.6m from Atlantic City's Borgata has taken another $1.1m from Foxwoods Casino in Connecticut.

Cheng Ying Sun and two accomplices won the money 'edge-sorting' in a game of mini Baccarat.

The technique involves spotting asymmetries on the back of poorly manufactured cards which can give the player a 6.7% edge over the house.

The cards used by Foxwoods allegedly contained a defect that allowed eagle-eyed observers to distinguish baccaratÂ's Â"goodÂ" cards ̶ 6, 7, 8 and 9 ̶ from less valuable cards.

However Foxwoods is refusing to pay up, claiming the trio of gamblers cheated.

Like Ivey did, Sun is suing the casino for her winnings, plus another $1.6m she had deposited beforehand as front money.

She alleges that the dealers were aware of what she was doing.

The lawsuit said: "If Foxwoods and Foxwoods management knew that plaintiffs were edge-sorting and let them practice their form of advantage play anyway – intending to keep their losses if they lost but not honour their winnings if they won – this would be intentional fraud."

Edge-sorting is legal in Connecticut.
