To the most of public, one of the most incomprehensible things about professional blackjack strategies is hole-card play. The one feature that can be found in all of these strategies is that the player either knows the dealer’s hole card, or has valuable information about that hole card. To most casual blackjack players, this seems absolutely incredible and impossible, unless there is some sort of cheating going on. But it’s not impossible, and in fact, most hole-card strategies are perfectly legal.
James Grosjean’s Beyond Counting (now out of print, though a second edition has been announced) is widely regarded as the hole-carder’s bible. A meticulous mathematician, Grosjean was the first person to accurately figure out the hole-carder’s edge at blackjack with perfect reads and perfect play (just over 13 percent), and in addition to his work on blackjack, he provided some of the first detailed hole-card analyses of games like Three-Card Poker, Let It Ride, and Caribbean Stud Poker.
Most players, even if shown a dealer who is flashing, would not be able to spot the hole card anyway. Holecarders spend hundreds of hours training their eyes to see something that flashes by in a fraction of a second, often cast in shadow.”
Hole-card players speak their own language and have their own heroes. Most consider card counting too weak to be worth the trouble. Many quickly attain notoriety in the casinos and a degree of fame among other pros that appreciate the rare skills they have developed. But let’s look at some of the forerunners of today’s players, describe some of the most common hole-card strategies, and get a historical overview of this type of legal strategy.
What is warp play? In the old days, dealers used to manually peek under their tens and aces to see if they had a blackjack before satisfying the players’ hands. This constant bending up of the corners on the tens and aces tended to put a warp into these cards if the casino did not change its decks frequently. An observant player could see the arc in a dealer’s hole card created by hours of bending the corners of the tens and aces. Warp play was simply using this information to make strategy decisions.
Spooking is something else again. It used to be standard procedure for dealers to manually peek under any 10 or ace to see if they had a blackjack, in which case they would immediately turn up the card and collect all bets without playing the hands. Some dealers, in peeking, angled the card in such a way that a person standing behind them, or sitting at another table on the other side of the same pit, could glimpse the card also. It wasn’t long before players started working in teams to take advantage of such dealers. The guy behind the dealer was called the spook. He would signal his buddies playing at the table with whatever information he could get on the hole card. Dealers don’t peek this way anymore, and this is one of the reasons why.
What is front-loading? A front loader is simply a sloppy dealer who flashes his hole card as he is placing it beneath his upcard. It’s actually a pretty descriptive term, since one common way that such a dealer inadvertently flashes the hole card is by tipping the face of the card up toward the “front” of the table as he is “loading” it. A player who sits in a seat that provides him a view of this card is said to be “front-loading.”
