re: Poker & Equity Matrix
It isn't a bad idea to look at your equity and villain ranges in common situations, aswell as looking at lines etc. However I think a chart like this just isn't a good idea. It's too rigid and that is not poker. Again I love the idea but perhaps when you're playing and you notice a spot where you're unsure, mark it and run it through pokerstove and analysis it. Go through your database and look for common spots, perhaps filter for all the times you had TPTK on a dry flop and see how you played. Then think through how you should have played vs each opponent you did play. Pokerstove it, post it here if you're still unsure.
I think charts are more useful for SnG's, not so much cash.
