How do you define a top poker pro? What are the skills you need?

Of course, most commentators will differ on the nitty gritty, happily spending hours discussing the multiple facets of the all-round player, placing their emphasis on the various skills in the multiple variations, adjusting their opinions based on deep-stack play versus turbo tourneys, ring games versus freezeouts. However, no matter the specifics, there are certain universal truths. You need to be able to play all variations of the game; show aggression where necessary, patience at other times; you need to know how to play the big stack and the short stack; you need discipline and focus.

In two words: you need to be Barry Greenstein.

Out on table Green 42, the furthest from media row, sits the Team PokerStars Pro who goes by that name. And as ever, he's giving a masterclass in at least three of those skills mentioned above. Unfortunately for Greenstein, those attributes most on display are the final three: knowing how to play the short stack, discipline and focus. He has never been higher than about 20,000 in chips for the best part of two days. But he's still in there and still fighting. Several thousand other players are not.

Watching Greenstein at the poker table is never going to remind you of a fireworks display or a Scandinavian-only double-flop eight-card Omaha hi-lo sit & go with a bonus prize for the most outrageous all-in move with the least connected cards. But there's so much more to learn from watching his play: apparently impassive and uninterested, it couldn't be further from the truth. He is watching and waiting; he is listening and scheming. If there is a more redundant piece of electrical equipment in the room than the boom mic that the TV crew has hovering over his head, I'm yet to see it. Greenstein says nothing, and is unlikely to even if he doubles up or busts out. It's just not his style.

Instead, he has four towers of chips: two of the dark blue kind, worth 100 each, a half-tower of the yellow 1,000 chips and a quarter stack of the 500s, used primarily for riffling. He's waiting for a moment to push them all in; he'll double them up or he'll bust. If he does the former, he'll probably be here for another couple of days. If he does the latter, he'll sign a copy of his book for his vanquisher, he'll shake their hand and he'll head silently into the night.

Either way, he has nothing to prove. Greenstein won another bracelet this year. He made the final table of the $50,000 HORSE event, his second in succession and third cash in three attempts in the event that supposedly determines the best players in the world. You know, scratch that "supposedly". The fact that Barry Greenstein is the only name on every single cash list from that tournament is enough to prove it beyond doubt.

Look up "Top Poker Pro" in the soon-to-be-published "Poker Dictionary" and you'll see a picture of Barry Greenstein.

Update: There is, of course, something inevitable about this, but before the ink was dry on that last post, Greenstein bust. He did exactly as predicted when the moment came, a signed copy of "Ace on the River" lies beneath seat three, and now its author is off. And yet all that written above still stands. He still has nothing to prove.

Just a few hours ago, Barry Greenstein was sitting at one of the most elite poker tables in the world, and certainly the most important of the day. Piles of money sat just feet away. As the tournament director read Greenstein's resume over the PA system, the crowd erupted in cheers. Scotty Nguyen doffed his cap in honor. After all, Greenstein is the only person to cash in the $50,000 HORSE event every year since its inception. There was no doubt about Greenstein's importance, both at the micro moment and in the big picture.

Just a few hours before that, Greenstein had bought into the the $10,000 Pot-Limit Omaha World Championship, a planned multi-table excursion with the $50,000 HORSE event. A flopped set of kings outrun by quad queens ended Greenstein's time there.

After earning more than $300,000 in the HORSE event and busting early from the $10,000 PLO event, most people would probably take an evening--or at least a few hours--to breathe. Not Greenstein. He walked immediately to the other side of the room to play...a $1,500 event.

It's hard to relate it to anything. Playing the Masters and then dropping down to play miniature golf? Flying an F-16 followed by a flight simulator? Getting dumped by Angelina Jolie and hooking up with Abe Vagoda? It's impossible to equate. Is it possible to take a $1,500 seriously after the week--the Series!--Greenstein has had?

In a word, yes.

I know this, because as the $1,500 HORSE event resumed after dinner break, Greenstein walked in the door and realized he was about to miss the first hand.

He ran to his table.

If there was a picture of how seriously Greenstein takes poker, it was watching him hot-step across the carpeted floor and slide into his seat before his last card came off the deck. That's where he sits now, in a field of more than 800 players and playing for a prize pool of roughly what first place in the $50,000 paid.

Nobody can truly get in Greenstein's head and know for sure why he does it, but he makes no real secret about the most basic of his intentions. There's quite a bit of money involved. He has side bets on who wins bracelets. He knows people are betting on him. He bets on himself, too.

At the beginning of the World Series, a poker forum poster suggested it was likely Greenstein wouldn't make a final table here. Greenstein responded promptly, offering to take action on himself and telling everyone he would carry money around in $5,000 increments if anyone wanted to bet. Four final table appearances and a Razz bracelet later and the original forum poster is eating some serious crow.

There's something else at stake here as well. Greenstein's performance in the 2008 WSOP has put him in contention for the Player of the Year here at the World Series. It will take a strong finish, but at this hour, it's not impossible.

Over the past couple of years, I've probably spent more time around Greenstein than any member of Team PokerStars Pro. As I look back and try to figure out why, it's clear there are a couple of reasons. First, he's been expectedly successful and due coverage on this blog. Second, he's intriguing beyond my ability to explain. I want to understand, but it may be on the outside edge of my ability to do so.

But, that doesn't mean I won't keep trying.

When most people win a World Series bracelet, the post-game schedule is pretty clear. It starts with photos and interviews, continues to a bar, and then ends with a great night's sleep.

Team PokerStars Pro Barry Greenstein is not most people.

It's not been twelve hours since Greenstein won his third World Series bracelet. His victory in the $1,500 Razz event was followed by the obligatory winner's photo and then a quick sprint across the room to the $10,000 Limit Hold'em Championship that had been in progress all day. Over the course of the evening, Greenstein had been spending his Razz breaks tending to his stack in the Limit Championship. His entry into the $10,000 event was a calculated one.

"I have side bets on bracelets, so there is incentive on me to play," he said. "I didn't expect the Razz final table to last as long as it did."

It's pure Greenstein. He never seems to stop. He was able to keep his stack above zero in the Limit Event and will play Day 2 today. He still had a few hours to reflect on his third bracelet.

"Even though I was more experienced than my opponents, I could have easily gotten knocked out anywhere along the road," he said of his final table run in the Razz event.

Because of that possibility and the side bracelet bets, Greenstein hedged and entered the $10,000 Limit event. If he got knocked out early, he would have a seat in the Limit event. And if he didn't, well there was the matter of winning a bracelet. Somehow, as is often the case in Greenstein's world, he ended up with the best of both worlds.

It's only been a few days since Greenstein came tantalizingly close to winning the No-Limit 2-7 Draw bracelet for a second time.

"The 2-7 No-Limit looked like a very easy win for me," he said, noting the small field and his vast experience in the game. To his disappointment, he ended up finishing third. "I got a pat ten and Jeff [Lisandro] drew out on it and that ended up being my undoing."

And so he moved on to the Razz event, where he never looked to be in serious trouble. Razz is just one of the games Greenstein plays well. In a side game, he is hard to match. Razz tournaments, however, are a different beast. "It's not like side games where you get to sit patiently," he said.

Still, the skill was there and took him to the final table, where nuance went out the window. Experience and a friendly deck pushed him all the way to the bracelet. "It's kind of hard to rate how I played compared to my opponents, but I got the best cards. I went on a sick run," he said.

Anyone who follows Greenstein's accomplishments will likely note he seems just a little different his year. It's for good reason.

In years past, it was not uncommon to see Barry Greenstein awake...always. Never one to pass up value, Greenstein's MO in the past several World Series was to play tournaments all day and side games all night. If he slept, it was in the few hours he could catch when the side games broke or tournaments had dinner breaks.

"Normally I play all night and start a tournament on no sleep," he said. "This year, the side games are not as good."

So, Greenstein is taking the extra time to catch a few z's and spend time with his kids. While five hours in bed a night is not enough to support most humans, for Greenstein it is a luxury that is bearing valuable fruit. He is one of several pros who have big time side bets on who will win World Series bracelets.

"Getting some sleep and playing these things, it means I am going to make some final tables," he said.

He's already done it twice this year and looks to do it some more. With just a couple of weeks until the main event, Greenstein has a full schedule in the meantime. His calendar is already marked for the events where he feels he has the best chance to win a bracelet: $5,000 Omaha 8/b , $10,000 PLO Championship, and $50,000 HORSE.

The poker media have already dubbed 2008 as the Year of the Pro. For Greenstein, that is a distinction that doesn't mean a great deal. His confidence and experience mean whether it is Year of the Pro or Year of the Little League, he will be playing as hard as he can to win another bracelet.

And this year, he's doing it with a good night's rest and another bracelet to his name.

Team PokerStars Pro Barry Greenstein has once again proven he can make the worst hand with the best of them.

It's only been a few days since Greenstein took third place in the 2008 No-Limit 2-7 Draw event. Tonight, he didn't settle for third or even second. He proved he is the best at coming up with the worst.

Tonight, after nine hours of final table play, Greenstein won the $1,500 Razz event at the 2008 World Series. The win marks Greenstein's third World Series bracelet. He earned $157,619 for the victory.

Greenstein's victory not only further solidifies his role as one of the best poker players in the world. It also keeps the World Series Razz bracelet in the PokerStars family. Last year at this time, Team PokerStars Pro Katja Thater won her first bracelet in the same event.

Greenstein now holds World Series bracelets in Razz, No Limit Deuce to Seven Draw, and Pot-Limit Omaha.

Congratulations, Barry, on another great win.
