Not a very active player these days, but wanted to chip in on an interesting topic. I always felt that pre-flop charts were important, as they are they are far more realistic remember than anything post-flop, and thus more realistic. Obviously there's a difference between perfect recall (I never got there) and remembering the standout exceptions (often 3bets) and general boundaries.
A few things that may or not help :
- I did manage (almost) perfect recall for the comparably simpler game of
blackjack just from having them sat on my desk and playing thousands of hands - it's slow but a sure way to get there.
- Learning from mistakes is very powerful, because you commit to memory - it's the (psychological) pain that makes you remember it. Every time you suffer a painful loss of a hand , make sure to take advantage of this - take a note and when you're later doing your analysis in poker tracker or similar, check whether you should have been in the hand to start with. Can do the same with other memorable hands, even if you won, as long as there's something memorable about it.
- Playing heads up is a great way to hone the process of following preflop tables ; obviously the tables are very different, but it can be a place to start.
