Quite a bit of what ISF is talking about is shown in the "KK on A high flop"thread by gabe. I am sure you have all read it by now. There is this light bulb that goes on when you realize what he is talking about and then the concept no longer applies to just KK on A high flops. You can memorise what to do with KK there, but what about QQ on a k high flop or KK on an A turn? What about JTs when you flop the nuts? They alls tart to become more obvious when you understand the concept behind checking the flop. You start to know what to do when your WB/WA. There is 169 hands in poker and a million flops and turn cards that can come after. You can't memorize moves based on the cards, the board and the 1000's of opponents stats you will encounter, you need to learn the concepts that allow you to dissolve the information and situations into obvious lines to take because of the opponents range, how it is effected by the board, previous actions and the money behind. It's a jigsaw puzzle, and you need to solve it, but once you do, the light bulb goes on, and you will know you have figured it out.
