Are there any antes at this level? It makes a big difference if there are.

Unless you can narrow the button's range to JJ-AA, AK, AQ you are getting the right odds to call. Could he only make this play with the hands I listed or do you think it's a wider range that he is making this move with?

If he only makes this move with JJ-AA, AK, AQ then this is a fold.

Hand 2: 25.5814 % 23.94% 01.64% { AJo }


and with a wider range it is a call....
