Schwartz apparently can't play because he's been barred from all British casinos.
But that didn't stop the outspoken Londoner from dropping by the Casino at the Empire to rail the action and a few horses he's put in the event.
"It's bullshit," Schwartz said. "There was something at the Vic [London's Grosvenor Victoria Casino] ages ago when I wouldn't take off my hat and now I'm nationally barred from all the casinos. But I've just snuck in and won about five grand on the roulette."
The brash 25-year-old burst onto the high-stakes online poker scene earlier this year posting significant profits against the likes of Tom "durrrr" Dwan, David "Raptor" Benefield and Phil "OMGClayAiken" Galfond.
But he's perhaps best known for the often visceral brand of trash talk he brings to the chatbox online.
Schwartz has verbally attacked just about everyone who's crossed his path, but he seems to have a particular dislike for Dwan.
"I don't like seeing durrrr just own off the poker world and just win all the money from all the other fish," he said. "I don't mind if Patrik [Antonius] and [Phil] Ivey win. I just can't stand durrrr. I can't stand durrrr's face, durrrr's voice, and durrrr's eyes. I can't stand anything about durrrr.
"He's just an arrogant social retard. He's spastic. There's not much more to say than that."
Schwartz takes particular issue with how he believes Dwan built his bankroll, claiming his money was made chiefly from beating Cirque du Soleil founder and reported high-stakes fish Guy Laliberté out of millions.
"He thinks he's the best, but he's just so annoying," Schwartz said. "People just don't even realize if Guy had not existed in this poker world, durrrr would be nowhere."
Although he's particularly vocal regarding his distaste for Dwan, the online phenom doesn't appear to be his only target.
Some of the biggest names in the game turned up for Day 1b of the WSOPE main event, including four-time WSOP bracelet winner Daniel Negreanu, 2008 WSOPE main event champ John Juanda and 2000 WSOP Main Event champ Chris "Jesus" Ferguson.
But Schwartz' respect for poker's elite players seems limited as well.
"All these big players that you hear of, like Negreanu and all these old guys, they all won when there was better fish around - that's why they're famous," he said. "Obviously they did well and took advantage of poker when it was easy, but now it's tough. It's fucking hard to win now."
In recent months, the name __FullFlush1__ has been missing from the high-stakes games on Full Tilt Poker.
Schwartz says he withdrew most of his winnings from the site and because of a $5,000 per day and $15,000 per month limit on deposits, and a bit of a bad run trying to spin up the relatively small deposits into a sufficient bankroll for the bigger games, he's been forced to take his action elsewhere and avoid any confrontations with his nemesis Dwan.
Dwan is currently in London taking part in several events, including Matchroom Sports' durrrr Million Dollar Challenge, where he will take on Sammy "any two" George and a series of players yet to be named in 500-hand live heads-ups matches with a $500k buy in.
But Schwartz said he is unlikely to challenge his rival there.
"I'm not much of a live player and sitting down with $500,000 is obviously quite deep, so it's not the first thing that comes to my mind," he said. "But I would like to do a challenge with him of some sort at some stage quite soon."
It appears more likely that he will eventually meet Dwan online in Full Tilt's 50,000 hand durrrr Challenge, although Dwan is still in the midst of taking on Antonius and Schwartz isn't quite sure he's ready.
"I'd like to do that," he said. "I'd do that right now at $100/$200 with durrrr snap, but $200/$400 is a bit much. I suppose I could do that with my roll right now, but I'd feel like I was short if I started getting stuck right away."
Both players are set to take part in the PKR Heads Up Grand Slam in London beginning Oct. 8 and will meet there if they both reach the semifinals.
Anxiously awaiting the start of that, Schwartz sounded more than eager to get a shot at Dwan no matter where it is.
"I've smashed him," he said. "I'm up like 600 grand on him online. I would be up 800 grand, but we did these 200 grand flips when I was tilted one day and he won both of them. I kill this guy. This guy is like an autistic retard. If you just get a little bit into his head he can't deal with it.
"I'm sending him broke before the end of 2010. That's my goal."
