i do agree with 3bet pre and get AI pfr against a short stack. and this may be a leak that i am afraid to do it AKo, but i do it AKs often vs shortstacks.

but i dont really understand why get AI on flop. for me to make a good play by shoving means he should be calling my shove with QQ, AQdd and AJdd beside AK,JJ.

also EasyPoker and JR are right, i am a tigh player and i ussually tend to assign ranges based on what would make sense to bet depdending on board texture and HUD stats, sometimes my ranges may be very tight.
so what range would you assign him preflop and flop/turn for the line he takes?
