I'd like to discuss the profibility of the PF 4bet with AK

i mean, in FR micro stakes, i can understand it is feasible due to the loose-passive style common to the villains we find there, though i think in low-stakes and higher, 4betting with AK is mostly light against TAG sort of players.

Id like to know how do you play AK preflop vs TAG-regulars both oop and ip in fullring cash games.

in SH games i understand 4betting PF with AK is profitable because SH games are looser.

Long story short, whats the point in 4betting AK in FR games? isnt it better to call ip against TAG players?
