How Long-Time Poker Players Make Bad Decisions 

In poker, experience isn't always the best teacher. Sometimes players begin their careers 
doing bad things out of inexperience, and - just through plain luck - these bad things succeed 
at first. This reinforces that bad tactic or habit. The players fail to reexamine their strategy as 
the years go by, believing that they are on a solid poker foundation, while - in reality - it is 
cracking and sinking slowly, unnoticeably. 

This doesn't mean that these players all lose. Many win despite their mistakes. And that 
makes those mistakes even harder to correct. That's because, when things are going well, you 
don't tend to seek corrective action. You just suffer the diminished profit. You take the hit. 

Let's not do that anymore. Let's listen to a lecture I gave at Mike Caro University of Poker, 
Gaming, and Life Strategy in January. The topic was… 

Costly Mistakes Made by Experienced Players 

1.

  Mistake: Not raising enough on early rounds in last position.  

If ever there was an opportunity to establish your image at the same time that you gain 
a real tactical advantage, it's when one, two, and sometimes even three remaining 
opponents have checked to you on an early betting round.  

The advantages of betting are that you're likely to make your opponents "behave" and 
check to you on the next street (often when the limits double), and you can take 
control by (1) continuing to bet (for image, for value, or because your hand improved) 
or (2) checking and taking a free card. The more timid your opponents are, the more 
often you should bet. Simulations show that the times you knock potential winners out 
plus the times you win outright by betting is pure profit. The play is profitable even 
without this, and it is image enhancing. 

This doesn't mean you should always bet if everyone checks to you on the flop in hold 
'em or checks to you after the fourth card in seven-card stud. Sometimes you have a 
very weak hand and you should accept the free opportunity to improve, knowing that 
you would have simply folded had anyone bet. Sometimes you will just check along 
with the crown for deceptive reasons. Sometimes you will check because you've been 
betting too often and your strategy has become transparent. And sometimes you check 
because the opponents who have already acted are deceptive and tend to check-raise 
with great frequency. Those are not the ones you should bet into. 

Against them, usually take the free card graciously. 

But, in general, try to maximize your positional advantage on early rounds quite often. 
The more you can do this without stepping over the line and becoming a victim of 
your own aggression, the more money you'll make.  

Mistake: Letting the weakest players feel left out.  

2.

  When new recreational players come to your game, make them one of the group. From 

their perspective, they feel uneasy - and are less likely to gamble - if you talk only to 
other regular players. 

3.

  Mistake: Discussing strategy with opponents.  

This might make other opponents realize that there is strategy. Nothing makes weak 
foes less willing to gamble poorly than making them think you might be critical of 
their decisions. 

I never talk real strategy in a poker game. I babble, I mislead, I amuse, I laugh at 
jokes. I never, ever want opponents to think that they're being scrutinized. I want them 
to have my "permission" to play poorly.  

4.

  Mistake: Check-raising a timid player on your left.  

This is like crawling into a cave and waking up a hibernating bear. Why do it? The 
person on your left has a positional advantage, and as long as he remains timid, he isn't 
using that positional advantage to its full potential. Check-raising is often seen as an 
act of war. Why start it? 

The truth about check-raising is that it is compensation for the disadvantage of having 
to act first. It should be used, but it should be used sparingly.  

5.

  Mistake: (Hold 'em) Just calling the blind in a late position when everyone before 

you has passed.  
Despite what I've taught you about the pitfalls of playing very small pairs in hold 'em, 
this is the time you really can play them profitably, and the most profitable way is to 
raise. Then players often will check to you on the next round, and you can take 
control. The additional chance that you'll chase potential winners out, plus the chance 
that you might win right now, make raising the right play most of the time. 

Additionally, you should know that a small pair is often significantly more profitable 
against one opponent than against two opponents. If you flop three-of-a-kind, you 
probably want the extra opponent. But if you don't, you can sometimes win heads-up 
with that unimproved pair, whereas you would have been much more likely to lose 
with that pair against two or more opponents. 

If you play a small pair from early position (which, by the way, is not always a good 
idea), you should be hoping either for a lot of callers or just one (or, of course, none at 
all). You should not be hoping for two callers. That's why the correct play - if you do 
decide to play a small pair - is usually to just call from an early position and invite 
players into your pot. But in a late position, you want to either win the blind money 
right now or end up against just one opponent, not two. So, a raise is often the better 
choice. 

6.

  Mistake: Failing to bet medium-strong hands against non-threatening "calling 

stations."  
Players are afraid of overusing this tactic. Don't be. Stop fretting and keep betting! 
Weak callers make your bets with medium-strong hands profitable, especially when 
you act last. Usually bet. 

But make sure you understand that "non-threatening" was a key word in this mistake. 
If the players you're betting into are deceptive and apt to raise you back - thereby 
getting maximum value when they have you beat - you should not routinely bet 
medium-strong hands into them. 

7.

  Mistake: Asking to raise the limits when opponents are losing.  

This gives them new hope, and they tend to "start over" and play better. Also, if the 
limits are bigger than is comfortable, your opponents will tighten up. Remember, most 
profit in poker comes from opponents who play too loosely. 

8.

  Mistake:  

Splashing chips when bluffing. The more lively you bet, the more apt opponents are to 
call. In general, make you bluffs as unobtrusive as possible. 

9.

  Mistake:  

Not bothering to change seats. A lot of poker profit comes from positioning yourself to 
the left of loose players and, also, to the left of knowledgeable-and-aggressive players. 
Sometimes you can become glued to your seat and too lazy to make a change that 
would dramatically enhance your profit by allowing you to gain positional advantage 
against the correct players. Always be alert for a profitable seat change. 

And, of course, this has nothing whatsoever to do with superstition. You should never 
change seats for superstitious reasons, because everything I teach about poker - and 
everything that really works in poker - has nothing whatsoever to do with controlling 
luck or appeasing the poker gods. It has to do with powerful, proven strategy, 
psychology, and statistics. And it's all you need to win. - MC
