i used to follow it religiously. not anymore.

i still jam quite a few hands, don't get me wrong. but alot of hands i'm just limping or minraising now. because most of my opponents are idiots postflop - either too agrro or too tight. so if i minraise or limp AA, yeah my opponent's unpaired cards will flop two pair or trips 2% of the time, but he's often going busto with one pair or a draw.

that chapter in mathematics of poker is in the game theory/optimal play section. so, it's neutral to +EV, definitely not -EV (well there is the rake). but exploitative is more +EV.

and yes jamming can be exploitative against tight players. but there is no reason not to jam the minimum jam hands against loose players, because it's at worst neutral ev (again, not taking into account the rake), unless you want to wait for a better spot, but if a loose player is calling too loosely (looser than he is supposed to call according to the tables) then you're doing better than neutral ev.

anyways, it comes down to your opponent's style: both preflop and on the flop.
