Refutation to Abdul preflop tactics

[Nate tha' Great]

B-

Yeah. My understanding is that the classic variation of the always open raise arugment goes something like this:

There are some hands that it is somewhat more profitable to limp with, but limping gives away too much information. Therefore, you should raise or fold these hands to avoid information leakage.

The experimental results I have say something slightly different, which is that in certain very common game environments, virtually every hand intrinsically makes you more money if you open-raise with it versus open-limp. Avoiding information leakage is another perk, but even if your opponents had no memory whatsoever of your previous preflop actions, it would still be optimal to always bring it in for a raise.
