on the topic of the desirability of postflop information, i think you very definitely want to have a feel for villain's postflop game when making decisions as early in the hand as preflop. playing vs someone's steals is a prime example of this. we want to know whether villain is fit-or-fold postflop or a barreling monkey, or never folds to flop C/R's or always folds to flop C/R's etc etc. that said, i prefer to keep my on table hud relatively simple because then i must actively search for the things i want to know (and i do) rather than just a quick glance over some numbers on the table that i don't adequately take into account anyway. also, i hate table clutter.
