John Patrick Basic Strategy (long)
I don't have the book being discussed, but an article on johnpatrick.com (Free Gambling Tip #20 - Blackjack variations) gives a list of where JP says he differs with Basic Strategy charts. He also gives an amusing explanation for why he refuses to split 8s against dealer 10.
I'm curious as to how much EV is given up by this strategy, because I used to use John Patrick Basic Strategy myself. Before I did any real research into card-counting, etc., I learned how to play Blackjack from a $20 casino CD-ROM that happened to use John Patrick BS (pun intended) in its "strategy advice" feature. Laugh if you will, but at the time, it was an improvement for me. Now I know better.
For the curious, here's the article in its entirety (the site is in frames, so I can't just give a link):
"I just wanna go over a few variations to the time worn set of Basic Strategy charts that have been filtered down, lo these many years. Are these charts important in the playing of the game of Blackjack?
You bet your life they are . They give you the BEST MOVE TO MAKE.........based on your two initial cards, vs the dealers Up Card, the only thing that we can use to make our decisions.
However, I disagree with several of these suggestions and will lay them out here, with my opinion on one of them. Now this will not sit well with many �math wizards� who believe that the decisions they use are based on thousands of simulated runs, to tell us what is the best move to make in these situations.
My explanation for why I differ, has to do with what I believe to be the logical move in these situations. Here are a few of my differences
1) Split eights only against the dealers 2 thru 8.
2) Double ten vs dealers 3 thru 7
3) Double 11 vs dealers 3 thru 7 (I do not double vs 8 but that is your choice.
4) Split Aces vs dealers 3 thru 7 (I do not split vs 8 but that is your choice,
5) Split fives vs dealers 5 or 6
Those are a few that I have set aside and notice that there is no way I double the 10 or 11 nor split the Aces vs that dangerous deuce.
Let�s start with splitting eights vs that 9, 10, J, Q, K or Ace and I�ll use the queen as my example, but the theory applies to all of those cards.
You�re sitting with two eights and we�ll say you have a $5 chip on board. Dealer has a queen and a down card. Basic Strategy (BS) tells us to split and to place another $5 chip on the board.
Just for the sake of example we�ll say the dealer gives you a down card on each of those eights (I�m aware we play each hand out individually)
Now you have 8 with a down card and 8 with a down card. Think to yourself. If they gave you a choice as to which hand you would rather have (8 w/ a card or Q w/ a card, which would you choose?
The answer is obvious..........Q w/ a down card, because going in, you would have a stronger hand. But by splitting those eights, you put yourself in the position of risking an extra $5 and now giving yourself two hands, both inferior to the dealer who is sitting with Q and a card.
An argument could be made that having two eights vs the dealers Q is a bad hand. Naturally, but doubling your bet to make yourself now have two bad hands is not the answer. You are increasing the amount of money you have to bet, AND not improving your hand vs that powerful Queen.
Personally, I would surrender those two eights, in an effort to cut my original bet in half (to cut potential losses). Don�t give me the argument that they don�t have surrender......I would not play where there is no surrender option.
But if the games available to you NEVER offer surrender and you want to play BJ........then the hitting of those original two eights, vs that dealers power card is the right move. DO NOT increase the amount of your wager by splitting and by your own (obviously) opinion, now having two inferior hands to play with.
I don�t care that an argument could be made that over 1000 such decisions, you have a 2% better shot, or whatever pct. these math people put on these moves. Logically, you are not going to live long enough to have this happen to you 1000 times.
Besides, in a normal 2-3 hour session, this may only occur two or three times. When it does, don�t split and give yourself two weaker hands.
Hit those two eights vs the dealers 9 thru Ace and get to the next hand. That is the logical thing to do.....................JOHN PATRICK "
