Splitting Tens

by David Irvine on November 26, 2009

One blackjack hand that always draws attention, but can provide good value for the player if done under the right circumstances, is splitting tens. A while back I was playing at the MGM Grand in Las Vegas when I had the opportunity, and the good fortune, to split tens. The True Count was +7 at the time, which means I had approximately a 3% advantage over the house. That doesn’t sound like a lot to a casual blackjack player, but keep in mind that multibillion dollar Vegas casinos are built on fractions of a percentage, and it is actually very good.

I was playing two hands. My first hand was a Jack-Ten, and my second hand was a King-King. The dealer’s up card was a Six. I was trying to play by myself under the radar, and had wagered $600 on each hand. Basic Strategy – the mathematically correct way to play your hand versus the dealer’s up card – says to stand in this situation. Being a skilled player, I made a Numbers play, which is a deviation to Basic Strategy based on the count. As you know more information about the cards remaining to be played (as a skilled card counter does), then you can make adjustments to Basic Strategy called Numbers plays. The correct Numbers play is to split tens against a dealer’s Six if the True Count is greater than +5.

As soon as I said “Split” two things happened in rapid succession. First, the entire table groaned their displeasure. And second, the dealer shouted over his shoulder to the Pit Boss that I was “Splitting Tens!” So much for under the radar. I pulled an Ace (for a Jack-Ace) and another Ten (for a Ten-Ten). A few choice words were lobbed my way when I spilt the Ten-Ten a second time. I pulled a Seven (for a Ten-Seven) and a Nine (for a Ten-Nine). On my original King-King hand I stayed put. Of course, even this “correct” play caused some exasperated hand gestures and eye rolls from other players because now I wasn’t being consistent, according to the other players at the table. I already split tens twice, so why not the third time, their logic goes? To them, the only thing worse that not playing Basic Strategy is to play inconsistently. But I was playing consistently, consistently making the correct play!

So why didn’t I split the King-King? The answer is that when you split tens the Number increases by 1 every time. The first time the number is +5 (i.e., if the True Count is greater than +5, which it was, then split the tens), the second time it is +6, and so on. In order to split tens a third time, the True Count would have had to be greater than +7. By that point, it had decreased to less than that so I followed Basic Strategy, instead of the Numbers, and stood pat. One of the biggest myths in blackjack is that how one player plays his hand can determine the fate of the entire table. If only the player at third base had stood on his 16 and not taken the dealer’s bust card. If only that moron had not split his 10’s and screwed up the flow of the cards for everyone. This type of thinking is nonsense and a big waste of time and energy. Gamblers tend to have very selective memories and focus only on the bad bets. In the long run the decisions that other players make, no matter how bad, have no effect on whether you win or lose. The only player you should be concerned with is yourself. How well you play determines whether you win or lose. Not hunches. Not superstitions. Not other players.

I almost hesitate to tell you what the dealer had and the outcome of my hands (but I will), because that defeats the purpose of being a skilled blackjack player. A Professional Blackjack player is concerned with one thing: making correct decisions, every time. The actual win or lose is secondary. If you make the correct decision every hand, then the money will take care of itself. In any event, the dealer turned over a ten (for a 16), and then pulled a ten and busted. All told, I won my four hands for a quick $2,400. The best part was that all the other players at the table left in disgust so I had the table all to myself and made another $3,800 before the cut card came out. By this time I was getting some heat from the Pit Boss, and decided not to press my luck – there is always another casino right down the street. So I collected my chips, hit the road, and dropped back under the radar.

How I Got Started On the MIT Blackjack Team

by David Irvine on June 26, 2009

For my first "real" post, I thought I would talk a little bit about my background and how I got started on the MIT Blackjack Team. It all started in the summer of 1993 while I was spending the summer taking classes and living in my fraternity, Delta Upsilon (DU). Over the summer, we often had non-DU members live in our house to help with expenses, and one of my housemates that summer was my good friend Mike Aponte. Mike would always disappear for the weekend, and then come back with wads of hundred dollar bills and an uncorked bottle of Dom Perignon. He actually had about 20 bottles of Dom all lined up on the faux-fireplace mantle in his room. Now, being a poor college kid, I had never seen a hundred dollar bill before, let alone bought stuff with one. Here I am eating Raman noodles at 12 boxes for a dollar, and Mike is buying sushi every night and paying for it with $100 bills. Thankfully, Mike finally let me in on his little secret and one day asked if I wanted to join the MIT Blackjack Team.

Growing up I wasn’t into blackjack and didn’t really even know all the rules of the game. The only thing I knew about card counting was what I had seen in the movie, Rain Man. But curiosity got the best of me and I decide to attend a team meeting. At that meeting I learned two things. 1) Card counting is a legitimate, mathematically proven system that can actually beat the house, and 2) that I would have the opportunity to go on some pretty awesome trips. I would have the opportunity to bet thousands of dollars and live the life of a high roller. For a young college kid it was like a dream come true. I had nothing to lose, right? At the very least I thought it would be a nice change of pace from doing my differential equations homework. So, I signed onto the team immediately.

Trip to Atlantic City with "Martinez"

My first trip to Atlantic City was with Martinez, one of the main characters from the book "Bringing Down The House" by Ben Mezrich. Martinez is another one of my good friends, and also was one of my housemates that summer. When we first got to AC the weekend started off a little rough and we had trouble getting action until right before we had to catch our plane back to Boston. We decided to walk down to Trump Plaza for a little bit and we ended up winning about $55,000 in less than an hour. $55,000 in an hour!!!! I was as totally hooked! I often wonder what would have happened if we would have lost $55,000 that weekend. Even though it wasn’t our own money at that time, losing more money in an hour than most people make in a year really puts a knot in your stomach. A common theme of the people who actually played on the team is that we won money our first trip. Luckily, I was one of those, and kept playing on the team until my last trip in 1999.
