you have to call 7,7 into a 20,85 pot so you need 36% equity vs his range.

AKo vs JJ+,AK has 39% but his 5bet AI range should be like 77+, AK and vs this you have 42% equity so it was a call.

and even AKo vs QQ+,AK has 38% equity, so any range you give him you can still make a +EV call here.

i doubt this guy is only shoving QQ+ here so we'd have to fold ( AK vs QQ+ has 31% equity)
