Here's my point. Sometimes you're in a situation where your hand is so strong that you should never lay it down. KQ heads-up with 13 BB, getting 2:1 odds, is one of those situations. But instead, we sometimes talk ourselves into making a heroic fold (which in a vacuum is BAD BAD BAD) because "well this guy is so passive and awful that he'd never do this without a hand that has us crushed blah blah blah" and we're usually wrong to do it. Even passive players get out of line sometimes so you shouldn't make horrible folds like this.

Most of the time, ABC Poker is what wins the money instead of making absurd call-downs with A high or folding sets or whatever.
