*************************************************************************** * DRAW POKER * *************************************************************************** Release 5.72 July 1993 Gellman Software 431 Fifth Street, S.E. Washington, DC 20003 (C) Copyright Robert Gellman 1987-1994 All Rights Reserved POKER plays five card draw poker head-to-head. The program provides a real contest for the serious poker player and helps weaker players sharpen their skills. But be careful. Many report this program is habit forming. The program attempts to play winning poker consistently. It has a sophisticated style of playing and betting designed to win more money than it loses. The program doesn't get tired or lazy, and it doesn't call bets just because it is curious. Can you play winning poker against a tough, disciplined opponent? That is the challenge offered by this game. The program allows you to play dozens of hands in a few minutes. You can acquire a lifetime of experience in two hours. Despite the limitations of head-to-head poker, you can still acquire a good sense of draw poker odds. Remember the basic challenge: Can you beat the computer? The program assumes that you know how to play poker and requires no manual. If you need help, there are several introductory screens with explanations of the program's operations. Two help screens are available during non-tournament play at the touch of a button. Now you can play even if you can't remember whether a flush beats a straight (it does!). *************************************************************************** * PLAYING THE GAME * *************************************************************************** To start the program, just enter POKER at the DOS prompt. The first few screens explain the mechanics. Try some hands and you will catch on quickly. The program will run under DOS 2.0 or better. The program requires less than 512K and is compatible with both color and monochrome monitors. A graphics card is not needed. If you have a color monitor but do not want color, start the program like this: POKER/BW. If you want to start playing, go ahead. Nothing in this short DOC file is vital. Read it over, but the documentation is not worth printing. The file was created with margins at 5 and 75. There are form feeds approximately every 60 lines. Words of wisdom: Bet your own cards. *************************************************************************** * TOURNAMENT * *************************************************************************** Version 5.7 added a new feature and a new challenge. You can now play a 100 hand tournament against the computer, with the highest scores preserved in a high score table. The tournament puts heavy pressure on each player to conserve resources and to make the most effective use of the cards dealt. During the tournament, the computer adjusts its play constantly to confuse and confound. All advantages (help, hints, and highlights) are turned off in tournaments. You have to pay attention and remember the order of hands and the number of cards that the computer drew. The tournament has a wider variety of minor features, cute comments, and occasional, interesting options. You will have to play to discover them. To find them all, you may have to play thousands of hands. That is, if you can afford to. On the bright side, you have unlimited funds in the tournament. After all, how much can you lose in 100 hands? More than you might think. In tournament mode, antes are $4 and the largest bet/raise is $40. These are the maximum stakes permitted anywhere in the program. The high score table is written to a file called POKER.HGH. The file is created in the current directory. To empty the file, just erase it. The program will create a new high score file when necessary. The computer plays tighter poker when in tournament mode. This means that there is both more folding and more bluffing. The computer is trying to win and not to entertain you. If you find this too boring or too difficult, then go back to the regular mode. The betting is looser, and you may find it easier to cope. Before you try a tournament, play some hands in the regular mode. This will help you to become familiar with the program's keys and procedures. Once you are comfortable (about ten minutes or so), you may find that the tournament offers more of a contest. The statistics shown at the end of a tournament are a bit more extensive. One of the most interesting numbers is the number of big showdowns. A big showdown is a pot which exceeds $50. Comparing the amount of money each player won in big showdowns sometimes explains the final result. But sometimes, careful play in small hands can overcome the loss of some larger pots. One word of caution: remember that half of the money you won in big pots is money that you put in the pot. If you play a lot of tournaments, I would love to see the results. After you have filled up the high score table with scores of your own, print out of a copy and send it to me. Just hit SHIFT-PRINTSCREEN when the high score table is on your screen. I want to know how well the computer is doing, and random results from a few players will help me to refine the betting algorithm. My address is at the top of this document and is also on the second screen (just hit ENTER at the opening screen). Thanks. *************************************************************************** * COMMENTS & ADVICE * *************************************************************************** First, the program is totally honest. The computer does not know what is in your hand unless there is a showdown. Nor does the computer know what cards are in the deck waiting to be drawn. The computer does keep track of all "public" information about your activities, however. Second, there is one minor, otherwise undocumented, feature whereby the program actually "cheats" in your favor. After cards are drawn, the program will "remind" you of how many cards the computer drew by displaying one period (.) for each card the computer drew. Given the fast pace of the game (once you get the hang of it), it's easy to miss the message showing the number of cards drawn by the computer. After the draw, the periods appear at the top of the display following "AFTER THE DRAW". On the showdown screen, the periods appear at the top of the display after the word "pot". This is DISABLED during tournaments. Third, be aware that the computer has different patterns of betting. Some of its betting is random, and it won't always bet the same way with the same hand. The computer also observes your play and modifies its behavior in response to your betting habits and methods. Tournament betting is highly variable, and changes constantly as the deals progress. The computer is also able to bluff in several ways. The computer will sometimes make large bets with bad hands and no bets with good hands. Like any good poker player, every move the computer makes has at least two possible interpretations. Fourth, a run of very good or very bad hands is just a coincidence. The randomness of the program has been tested in simulations involving over half a million hands. The results mirror those expected in normal poker playing. If you are losing, just keep playing, and your luck may improve. If all else fails, try playing better poker! Fifth, as you play, you will occasionally be offered the chance to increase the stakes and the ante. The maximum bet (or raise) starts at $10, and it can be doubled twice until it reaches $40. This is high enough for a game where each player starts with $200. Contrary to normal poker practice, the minimum bet remains at $1 even when the stakes are raised. In most games, the ante is equal to the minimum bet. In tournaments, the stakes are fixed at the maximum allowable. Sixth, in head-to-head poker, a high percentage of hands will be folded by one player or the other. This is normal. Conservative players fold when they don't think they can win. Of course, there will be occasional spectacular showdowns when both players have good hands. But the odds are that you are likely to win only half of these hands. Finally, remember that just because you have a great hand doesn't mean that you are going to win a big pot. If you make a large bet, a player with a mediocre hand (or worse) will fold. Learn how best to manage both good and bad hands to maximize your return. The key to winning poker is discipline. Play your cards and learn how to exploit small advantages. Over time, the luck will even out. *************************************************************************** * TECHNICAL NOTES * *************************************************************************** POKER has been more than twenty years in the making. The first version was written in FORTRAN in 1969-70 on an IBM 360 Mod 65. Later versions were written in IBM BASIC and ATARI BASIC. The current version was written and compiled in Microsoft's QuickBASIC 4.5. Version 5.60 was a major improvement over previous releases. Later versions were more evolutionary until version 5.70. The source code, which has not been released, is over 1800 lines. A serious programmer/poker player may be able to convince me to provide a copy of the source code. *************************************************************************** * FEEDBACK * *************************************************************************** If you find any errors, please let me know exactly when and how they arose. The program has been extensively tested, but I cannot guarantee that it is bug-free. My address appears on the top of this document and on the second screen (hit ENTER at the first screen). User feedback is hard to get. I welcome comments about the program, its mechanics, or poker strategy in general. Any suggestions for changes or improvements will be considered. If you find a bug or make a suggestion that I adopt, I will send you a copy of the new version. Finally, my thanks to the Study Group for poker lessons and to B.C., D.B., and S.A.C. for helping me refine the betting algorithm and the general look of the program. Thanks for Joe S. and Bill L. for testing the tournament version. Good luck to the rest of you. You may need it. *************************************************************************** * LEGAL STUFF * *************************************************************************** This program and its documentation are provided "as is" without warranty of any kind.

Minor betting adjustment. A few small changes to screens. Thanks to B. J. Ball for reporting the error. Version 5.71 - Added a command line switch (/BW) to suppress color. (3/1/93) Changed introductory screens to describe new switch. Version 5.70 - Major new feature: tournament play added, along with high (10/6/92) score table for tournaments. Fixed a minor error which prevented the display of the number of cards drawn by the computer when the player took only one card. Major changes to all betting algorithms. Changed insult content and frequency. Lots of minor adjustments. Version 5.67 - Fixed an obscure screen formatting error involving a (9/10/91) message that appeared when the player drew three cards to complete a hand with four of a kind. Changed the procedure for drawing cards. The F1 - F5 keys now work as toggles. The F9 key which used to restart the draw is no longer functional. Added a new final screen. Version 5.66 - Added F8 switch so that you can keep all cards in a pat (3/1/91) hand with one keystroke. Added verbal descriptions (e.g., KINGS OVER SEVENS) of hands at showdown. Both changes requested by users. Music for computer winning hand shortened. Other minor conforming changes made. Version 5.65 - Minor revisions of screen. Minor internal changes. (9/16/89) Added average pot information to final screen. Modified the "charity call" algorithm. Slight changes to both help screens. Revised documentation. Version 5.64 - Fixed an ancient mistake. The program failed to (1/22/89) properly evaluate competing straights when one was a baby straight (A-2-3-4-5). The program was "dazzled" by the ace and determined mistakenly that the baby straight was higher than another straight that didn't have an ace. It took 20 years for this error to surface. My thanks to R. Brosseau and B. Binford for reporting this problem. In the coincidence of the year, both wrote me on the same day! Version 5.63 - Revised the rules screen and added a new screen (1/10/89) showing the order of poker hands. Made both screens available at a keystroke. Revised the main screen display. Changed the sound screen and the opening sounds. Made the computer a bit more aggressive. Cutesy card cutting display added. Recompiled in QB 4.5. Version 5.62 - Modified the frequency of chances to raise the stakes. (7/31/88) Fiddled with frequency and content of insults. Eliminated extra keystroke in sandbagging situations. Recompiled in QB 4.0b - size reduced by 10 percent.
