over playing AK

[mudbuddha]

lately, i have been palying AK, i guess too aggressively, i make it a priority to isolate 1 player so that my AKo or AKs have a better chance, however, i think i am over playing this and making raises that are too large.. i guess.
(assume that i position.. i try not to be too invested when i have bad position)

is my thinking wrong on playing AK??
