VPIP Thought Experiment
Imagine that I spread 10,000 random preflop hand situations in front of you on a giant table to examine. Included in this 10K, is everything from super strong hands, like you holding Aces on the button and facing a raise and reraise in front of you by fishy players, to super weak preflop situations, like you holding 72o under the gun at a tough, full-ring table. Ten thousand different hand scenarios, all arrayed in front of you.
Now imagine that I ask you to sort these hands situations into two separate piles of cards: playable and non-playable. For the most part, this would be an easy exercise. The vast majority of hands would fall into the non-playable (i.e., fold) category. Of the remaining hands, many would make for easy calls or raises (i.e., playable), such as the aforementioned AA in late position facing action upstream. Some of the others would be legitimate close decisions (which in general you should lean toward folding, btw). And then there would be all those hands that you want to play, but you know you shouldn't. For example, we all know by now that we shouldn't call OOP with cheese like KTo against a TAg EP open raiser, right? Or open-raise in early position against fishy players with weak suited connectors like 54s. Or call a raise with a lowly pair of deuces if we're not getting the correct implied odds to set mine. And so on....
You get the drift. People often know they shouldn't play many of the hands they do, yet they do it anyway. They know intellectually that a bad play is a a negative-EV play, but they go ahead with making it for whatever reason. Sometimes it's boredom that drives us to do this. Other times we're just "feeling lucky" and want to gamble it up. Frequently it's because we're tired, distracted, not paying attention, or just plain tilting. Maybe the hand in question is your "favorite hand" and you always play it. Or you "feel" a win coming. What ever the reason is, it's a bad one if the play is -EV. You do understand this, right? Right?!?
Okay, back to our thought experiment. Let's say that I change the rules a bit. Instead of just sorting into playable or non-playable hands, I add a requirement that says you cannot have more than 1500 hands in the playable stack. Not one single hand more. This sounds like a big number, but it's not; it's just 15% of the hands that are dealt to you, so you have to be judicious. You have to selective. You do not have room in the 1500 for cheese hands, trap hands, bad hands, bright-and-shiny hands. In other words, you don't have room for any of the -EV hands.
Said another way: knowing that you're only going to be allowed 1500 in the playable stack, are you really going to slip that KTo-facing-an-EP-raise hand into the playable pile? I didn't think so. What about the 54s-in-EP? Nope, not a chance. Or the ducks-against-a-shallow-effective-stack? No way, Jose.
Preflop, you have to think in terms of playable vs. non-playable. Playing poker preflop is really the same as picking which 15% of the the 10K hands you're going to bet your hard-earned money on. The only difference is that you have to wait and see the 10,000 hands one at a time, and not all spread out at once.
A playable hand situation is a playable hand situation. And a non-playable hand situation is a non-playable hand situation. Learn to tell the difference... and you're on your way to printing money.
All-in for now...

Player Types - Part 2
In my last post (here) I wrote that we can sort the players we face at a poker table into seven basic categories. These categories are based on two distinct preflop traits of the player: VPIP and PFR. One way to visualize this is to create a two-axis graph with VPIP along the horizontal X-axis, and PFR up the vertical Y-axis. Every player we face at the tables can be located somewhere on this chart. The more hands the player voluntarily gets involved with before the flop, the farther to the right they are on the chart. Similarly, the more aggressive they are before the flop, the higher they get placed in the vertical direction:
For example, a player who only plays premium, high-quality hands, but does so in a relatively passive (read: non-raising) fashion, is said to be a Nit or a Rock. This person would be found in the lower left of the chart. When a player like this actually does raise, you need to look out; he or she probably has a very, very big hand:
In contrast, so-called Break-Even or Recreational players typically understand that they need to play more hands than a Nit, but they sometimes go too far. They also know that they're supposed to raise, but they haven't quite mastered the skill of applying aggression hard enough and/or selectively enough in their game to win consistently. This type of player is usually someone who has read a book or two on poker, and is trying to play properly, but isn't quite there yet:
Then there are those players who take the idea of playing more hands way too far, but also remain relatively passive. These players are called P-Fish (for "Passive") or Calling Stations. Players like this usually can't be bluffed very effectively, so the way to beat them is to take them to value town with your good hands, and quit when you miss:
If someone plays a lot of hands like a P-Fish, but does so in an aggressive manner, we would call him or her an A-Fish (Aggressive Fish). At the extreme upper right hand corner of this group would be the so-called Maniacs. Like P-Fish, bluffing doesn't work very well with these types of players. Betting for value is usually a good option against them, but just as frequently you an let them bet for you; i.e., you can play more passively against them with your big hands, letting them bet and raise, and you just call down. At some point in the hand, when they feel pot committed, you can start raising, too:
In the upper left hand corner of the VPIP vs. PFR chart are the players that are Level-1 and beginning Level-2 winners. This is what is usually taught to new students of the game as the basic formula for winning. TAG (Tight-AGressive) or Reg (for "Regulars") are the standard terms used for these players. They play a selective group of hands, and when they do so they play them very aggressively. This is the most common way to play winning poker, especially at the low limits. It can be a bit ABC and, therefore, exploitable. These players are also bluffable:
To the right of the TAGs on the chart are the so-called LAG (Loose-AGressive) players. Most professional players and solid Level-2 players adopt this style of play, as it's more profitable (and less exploitable) than plain ABC TAG play. On the other hand, it's much harder to play this style, and you have to be really good at reading your opponents' hand ranges. The variance can also be more extreme on your bankroll via a LAG approach:
Here are all six basic types shown together:
But wait a minute. Didn't I write that there were seven types of players based on VPIP and PFR? Yep, I sure did. The seventh player is the true master of the game. This is the villain who actively changes his style of play to counter the way his opponents are playing. I call this type of player the Gear Change Specialist, or GCS, as they can effortlessly shift gears, moving their starting hand requirements between tight and loose, and their aggression between aggressive and passive to suit the current table dynamics. If they find themselves at a table of Nits? No problem, they adapt by playing somewhere between LAG and Maniac. Their opponents are Recreational players? Again, no problem, they adopt a basic TAG style. They're surrounded by Maniacs? Again, no problem; they simply tighten up their range and play more passively.
When players first start out, they almost always play a Nit or P-Fish style, with an emphasis on the latter. As they get better, they transition to Rec style, and eventually, TAG. Then they begin playing LAG, but frequently go back and forth between TAG and LAG as their bankroll gets beat-up and they learned the winning LAG style. And finally, at the higher stakes, winning players either stagnate at TAG or LAG style, or they truly advance their game by morphing into the GCS style. IMHO, this is where you should strive to play... and if and when you do master Gear Change Specialist style, you can exploit and attack the other six styles with ease.
All-in for now...
