180 manner - calling range in this spot?

[AAroddersAA]

What would your calling range be here? We have been at the table 8 hands and the villian has folded all of them. Then he shoves for 20BB.

The table so far looks fairly standard with nobody OOL really (based on a VERY small amount of info).

I was thinking his most likely range is AK and mid pairs up to JJ?

What is the correct calling range here?

It is a $4.50 180 manner (non turbo - so 15 minute levels). About 60 players remain at this point with an average stack of

Probably TT+ AQs+ but may drop AQs from this range in certain situations and call with 99 in others

[s4ooter]

Im a nit here

20bb shove in these is just plain vile

AA, KK, QQ, AK and thats about it for me

[WYoung83]

99s+ AQo + for me sounds good.

[Zozzy]

Without any signs of tilt, or any history with villain I am folding 10 10 and AQ

[Drewski]

If I feel I have an edge in general at this level then I would be a nit here and wait for a better spot with more info. AA, KK, QQ, AKs would be my range. Do I flip for more than half my stack here? I have a decent M and I would wait.

JJ+, AK
