Poker Rules Of Engagement


1. Bring an ACE. Preferably, bring at least two Royalty cards. Bring all of their friends who are connected to Royalty.
2. Anything worth betting on is worth a raise. Aggression is cheap. Passiveness is expensive.
3. Only hits count. The only thing worse than a miss is a slow miss.
4. If your image is predictable, you're probably not raising enough nor using position correctly.
5. Move away from your attacker. Distance is your friend(Unless you have him out gunned, then draw him in for the kill.)
6. If you can choose what to bring to a shootout, bring an ACE and a friend of Royalty.
7. Ten years from now, no one will remember the details of the game, hand, or tactics. They will only remember who won.
8. If you are not betting, you should be observingcounting stacks, and tagging opponents.
9. Aggression is relative. This is a BIG one. (Most aggressive action will be more dependent on "pucker factor" than the inherent validity of the hand)
10. Use a position tactic that works every time.  (All skill is in vain when an big stack thinks you are weak)
11. If you are unsure of a course of action, do not attempt it. Timidity is dangerous, better to enter with boldness. The end is everything.
12. Always Lie; Conceal your intentions. Cultivate an air of unpredictability. 
13. Always have a plan and have a back-up plan, because the first one won't work.
14. Use cover or concealment as much as possible. The visible target should be in FRONT of your gun.
15. Do not give comfort or information to the enemy.
16. Don't drop your guard.
17. Challenge. The risk of never challenging is always greater than the risk of challenging.
18. Create Fear. If your opponents aren’t sure what attacking you will cost, they will not want to find out.
19. Do not fight the LAST battle: Use Guerrilla Warfare of the Mind.
20. If you have the opportunity to eliminate your opponent, you must do it. It is the rule in war!
21. Be polite. Be professional. But have a plan to kill everyone you meet.
22. Be courteous to everyone, friendly to no one.
23. Everyone has a weakness. Find it and exploit it.

Limping & Sun-Tzu



I was watching one of the poker shows on TV, I try to record most of them. One of the announcers asked the other, "I wonder what The Art of War (Sun-Tzu) has to say about limping?"
Being a advocate of The Art of War and Poker, I thought I'd take a look at it. There has already been a good book on the subject written by David Apostolico, Tournament Poker and the Art of War, and there is also a web site devoted to it. Sun Tzu's Art of Poker

From "The Art of War" by Sun-Tzu
In battle, there are not more than two methods of attack:
the direct -betting/raising- and the indirect -checking/limping-;
These two in combination give rise to an endless series of maneuvers.
The direct and the indirect lead on to each other in turn.
It is like moving in a circle — you never come to an end.

Masking strength with weakness is to be effected by tactical dispositions.
Thus one who is skillful at keeping the enemy on the move maintains deceitful appearances, according to which the enemy will act.
He sacrifices something, (so) the enemy may snatch at it.
  • Simulated disorder postulates perfect discipline, 
  • Simulated fear postulates courage; 
  • Simulated weakness postulates strength.
If we wish to fight, the enemy can be forced to an engagement even though he (is) sheltered behind a high rampart and a deep ditch -a wall of chips-. All we need do is attack some other place that he will be obliged to relieve.
If we do not wish to fight, we can prevent the enemy from engaging us even though the lines of our encampment be merely traced out on the ground. All we need do is to throw something odd and unaccountable in his way -Randomness.
  • The rule is, not to besiege walled cities if it can possibly be avoided.
By holding out baits -limping/slow playing-, he keeps him on the march; then with a body of picked men he lies in wait for him.
By holding out advantages -showing weakness- to him, he can cause the enemy to approach of his own accord; or, by inflicting damage, he can make it impossible for the enemy to draw near.

Whoever is first -to act-with-active or passive Aggression- in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle - will arrive exhausted.
  • Hence that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.
Numerical weakness - lack of chips - comes from having to prepare against possible attacks; numerical strength -many chips-, (by) compelling our adversary to make these preparations against us.
  • Though the enemy be stronger in numbers, we may prevent him from fighting. 
  • Scheme so as to discover his plans and the likelihood of their success.
If we are able thus to attack an inferior force with a superior one, our opponents will be in dire straits.
  • When you engage in actual fighting, if victory is long in coming, then men’s weapons will grow dull and their ardor will be damped.
Do not repeat the tactics which have gained you one victory, but let your methods be regulated by the infinite variety of circumstances -Randomness- .

Water shapes its course according to the nature of the ground over which it flows;
the soldier works out his victory in relation to the foe whom he is facing.
Therefore, just as water retains no constant shape, so in warfare there are no constant conditions. He who can modify his tactics -Randomness- in relation to his opponent and thereby succeed in winning, may be called a heaven-born captain.
  • So in war, the way is to avoid what is strong and to strike at what is weak.

Way Ahead or Way Behind?



How many hands can beat you? What's your position? Who are you up against?

I forgot this concept when I had JJ, in position, recently, in a live ring game. Dealt JJ the hand before and got an easy win. The gods must have been smiling, or smirking, when on the exact next hand I got JJ - again, called a small raise, everyone else folded, so I was heads up against a good, loose aggressive player. The flop went something like 952, rainbow, and he bet about half the pot and I called. The turn was something like a 7, he bets about half the pot, I raise the pot, he re-raises, and I go crazy stupid All-in and get called. He shows QQ, the river is a King.

What was I thinking? I wasn't!
You hold an over pair to the board, but it's not the nuts! The boards not scary, but you could be behind a set, even 2nd or third best set, yet alone the top set. You could be behind the three top pocket pairs that can beat you.
You could be way ahead of any other hand and up against a drawing hand, or NOT.

A "Way Ahead or Way Behind" situation requires the following:
• You are heads up, before or after the flop, and you at least have a pocket pair or paired the board on the flop.
• You do not know whether you are ahead or behind?
• If you are ahead, your opponent has very few outs (typically two or three).
• If you are behind, you have very few outs.

Pot control is the key!
Controlling the size of the pot in your favor is crucial to your success as a poker player. The theory is simple: reduce your losses to a minimum and increase your winnings to a maximum.

When you have hands on the extreme ends of the scale, putting this theory into practice is fairly easy - if you have the nuts, you pump the pot; if you have rags, you fold. According to the theory of pot control, you should be working to maximize your profit in this situation. Only a few of the possible starting hands will have your hand dominated here.

If you automatically fold every single time you're in this situation, you'll lose every pot. The amount you lose will only be equal to that of your preflop contributions. This is a small loss, but a guaranteed one nonetheless.

Before you can decide how to play the hand, you have to figure out which opposing hands are good for it, and which hands are bad for it. Any constant loss is a leak in your game; too many leaks and you'll cease to float.

The players with a hand better than yours will be wanting to extract maximum value from their hands as well. Oftentimes, unless you can discern a very good reason to do otherwise, you want to control the pot, and keep it small by betting and checking. Usually you want to play Small Ball.

Who's bluffing?
Players are less inclined to bluff at a small pot, helping to eliminate the risk of the worse hands stealing the pot away from you. It also allows you to make bluffs and moves with less risk. The smaller the pot is, the less money it takes to make a bluff at it.

Don't get greedy! It will ruin your game!
Your goal is to extract as much, if not more, value from the hands you beat as you give to the hands that beat you. The times you successfully bluff a stronger hand into folding should be enough to render your hand profitable.

The most important concept to remember with a way ahead/way behind hand is that the only players willing to call a large bet will be the players who have you beat. For this reason you want to avoid large bets and large pots. Control the action, control the pot and wait for your spots to punish your opponents.

While "Way Ahead or Way Behind" confrontations are somewhat common, you must be careful to identify them correctly. If your opponent is semi-bluffing, for example, with eight, nine, or more outs, you must play far more aggressively. Only when you can be sure you are in a textbook "Way Ahead or Way Behind" situation can you afford the passive play that typically optimizes your results.

For the most part, poker is not an adrenaline-crazed action game, it's a patience game. The players who are able to control the pots, and play the grind, are the ones who still have chips left when the perfect situation arises.

Play strong, play smart and when you are dealt the nuts
milk it for all it's worth.

Tribute to Chris Ferguson



A Beautiful Theory
Forbes 12.14.06 b Tim Harford
http://www.forbes.com/2006/12/10/business-game-theory-tech-cx_th_games06_1212harford.html

A revolution in the social sciences began in the 1920s, when the man Time magazine called "the best brain in the world" decided he would work out how to win at poker. John von Neumann's quicksilver genius accelerated the development of the atomic bomb by a year, and he was one of the fathers of the computer.

Armed with Von Neumann's mathematics, even a computer could learn when to bluff. Real poker is hugely more complicated--and so, too, is real life. Von Neumann may have played down this objection because he and Morgenstern developed a theory of "zero sum" games, such as poker, where one player's loss is the other player's gain. If you play the optimum strategy in that sort of situation, and the other player makes mistakes, you will win. But real-life games are not usually zero-sum. It is also a reminder that in most situations, the point is not to beat some opponent but to do well for yourself. That will involve understanding the man on the other side of the game. If you think he is rational, and he isn't, your strategy will go badly wrong.

Some brilliant mathematicians and economists have worked hard to patch up these holes in the Von Neumann project, including Nobel prize winners, the most famous of them all is John Nash. Von Neumann, consumed with envy, dismissed the young Nash's result as "trivial"--meaning, mathematically simple. Sure, it was simple enough, but only (when) Nash had pointed it out. As a practical advance in game theory, it was far from trivial.

The year 2000 saw a landmark in the use of game theory. It was pure Von Neumann: a lanky computer scientist by the name of Chris "Jesus" Ferguson won the World Series of Poker using the game theoretic calculations he had developed, run on powerful, modern computers, and committed to memory.

Game theory has a lot to contribute to the analysis of life, love and economics. But the game will only go according to plan if you're sure the other fellow knows the rules. In the immortal words of Dalton from Road House, "Be nice, until it’s time NOT to be nice".

Players You Want At Your Table


http://www.askmen.com/poker/poker_tips/21_poker_tip.html
There are certain players who you always want at your table.
For different reasons, the players listed below make great tablemates, and the more you play with them, the more money you’ll have in your pocket in the long run. Here is a list of poker players that you should always have at your table.

Players with favorite starting hands
Why is their favorite hand usually something dreadful like K-J or Q-10? All we can do is be thankful and hope that we get them at our table. If they are at your table, you are going to be able to use this information for specific situations that arise. It is probably also an indicator of their general comprehension of the game. (My favorite starting hand is pocket aces… even though they will be busted a minority of the time).

Players with starting hands they hate
Ironically, these are usually strong hands like J-J, A-Q or even A-A. If you have these players at your table, watch for sudden over- or under-betting. It may indicate that they are holding one of the hands they hate. This “hate” is really just disguised fear of misplaying the hand, so they overcompensate to one extreme or the other.

Players who believe skill is better than luck
These type of players are very easy to put on tilt. Play some connectors and small pairs until you hit something on the board; then watch them spin out of control.

Players who are human calculators
Their strength of understanding the math down to the decimal point is also their weakness. Just make a bet large enough to destroy all of their pot odds and, unless they are holding aces or kings, you are golden.

These next players may be annoying, but you'll win with them at your table...

Players who think those who raise are bullies
These players believe that you should wait for proper cards to play at the appropriate time and they probably do very well in Limit Hold’em. You can usually tell who they are in a no-limit game because you have gotten most of their chips through numerous small pots.

Players who tell bad beat stories
These players are part of the group that feel skill should always overcome luck -- again, very easy to put on tilt. Give them another story to tell.

Players who are condescending
They are convinced that their poker ability is superior to all others, and they are outraged that you would call them with that hand, blah, blah, blah… The key to these players is that they are extremely insecure. They fear confident opponents and opponents who they cannot push around. I often think of the quote from the movie Gladiator when Russell Crowe’s character says to the emperor, “The time of honoring yourself is soon coming to an end.” you can bet on it

While playing with serious players who win all the time can really help improve your game, having a few flawed players at your table can also help you tremendously. Now go find some new tablemates and win yourself some cash.
