People are Irrational
Ever been driving down the street and see some idiot swerve across four lanes of rush-hour traffic to avoid missing turn? Of course you have, it happens every day. A common response to that occurrence is probably, "Wow, what an idiot!" or "What is that guy thinking?" The fact is that the majority of people you come into contact with in on a daily basis are the person who doesn't think twice about making the desparation lane change in order to save the hassle of turning down the next street or making a U-turn.
Now think about all the times you've been sitting down at a poker table (live or online) and someone makes a play that baffles you beyond belief. I'm willing to guess most of you have that reaction several times per poker session. I know I do, especially when I am the victim of the dreaded donkey punch. The question is, after playing hundreds, thousands and maybe even millions of hands of poker, why should I, or you, be surprised by the irrational play of your opponent? The answer is, you shouldn't be surprised. However, as rational people, we condition ourselves to believe that the person sitting across from you at the table is also rational and capable of making intelligent decisions. Hell, it's human nature to want to give someone you nothing about the benefit of the doubt. A wise man (Coach) always says, "You can't expect people to think rationally." (Or something along those lines).
As an example, let's take a look at a hand I played in the Daily Double. (Note: the point of this is not to bemoan my bad luck, tell a bad beat story, accuse anyone of cheating, or allege that Full Tilt is rigged.)

If you're in parenting101's position, what goes through your mind when you look down at Td Kd? A rational player probably looks at a few things when deciding how to act and can easily conclude what the correct play is in this situation. Let's pretend that I'm parenting101 and I'm a rational player. The first thing I notice as a rational player is DJM5255's stack size (approximately 11 bbs). The second thing I notice is that DJM5255 just raised a quarter or 25% of his stack from middle position. The third I notice is the location of my cursor in relation to the fold button so I can click it as quickly as possible before irrational thoughts creep into my head.
However, as we all know, parenting101 is not a rational player and decides to reraise all in. You all know how this plays out before you even see it, but I will appease your curiosity and post the result anyway.

This is a prime example of an irrational play. Only an idiot, half-wit or otherwise would think shoving is the optimal play in that situation.
The purpose of this blog is to drive it into your brain that thinking your opponent is rational and capable of making rational decisions is the WRONG WAY TO THINK AT THE POKER TABLE. Unless you have information on a player, the correct way to play is to assume the person you are playing is an idiot, and play accordingly.
