Hey guys, IMO JJ is the bottom of our range to call here - Ran it through ICMIZER and it says the same (JJ+ to call - AKs is a fold!!!)
Curious to know what you do here with jacks here and what is your range for calling in this spot?
Button is a lag probably shoving his all range here and SB is a very good reg.

i can say one thing about this spot...

You should overcall pretty tight generally but Nash calculator gives

BU 45.7%, 22+ Ax+ K2s+ K7o+ Q3s+ Q9o+ J5s+ J8o+ T6s+ T8o+ 96s+ 98o 86s+ 75s+ 65s 54s
called by SB 11%, 66+ A8s+ A9o+ KJs+
overcalled by BB 5.9%, 88+ AJs+ AQo+

What ranges is it/are you using for the other players?

If you are using automatically generated ranges I suspect you have a typo in your stack sizes at some point. If you make the stack sizes exactly 9614 for all 7 players at the table you get

BU 56.9%, 22+ Kx+ Q2s+ Q7o+ J2s+ J8o+ T2s+ T8o+ 95s+ 98o 85s+ 87o 75s+ 64s+ 53s+ 43s
SB 7.1%, 88+ ATs+ AJo+
BB 0.9%, KK+

-you've not gone that extreme but at some point it you're not getting full credit for covering these players.
