If you have a good stack don’t risk half of it calling all ins with AK. The the main value of AK lies in its fold equity, the value it has when called is a safety net only. I’ve just come 8th when 5 places won a $109 ticket, I called a shove of 45 K when I had a stack of 83K, blinds at 4K , and was facing KJ which was great. He he hit his Jack and next hand I was out running into QQ. There was no need, avoid variance especially in flat payout structure tournaments.
