Do you seriously think that becoming more passive post flop is a good idea ?
If so, please explain why?
If anything, I would think there is more of an argument for being passive preflop, and more aggressive post flop (tp-a), than for your position. Your opponents will make more mistakes post flop than preflop (after all, how hard is it to learn starting hand values based on position?). Have you seen the tournament hu match where Gavin Smith proposes to his (amateur) opponent that they agree not to raise preflop at all? Why do you think he wants this (hint: see above)?
