KK line check NL5

You're calling $2.70 into $7.56 pot

you need 25% equity to call.

Unless you've got reads that villain never raises, it's an easy call. Even then you've got at least 20% vs any hand w/o the Ad so its not a horrible mistake calling either

Theres enough AdX QdX JdX hands alone that he could be doing this with to give you 25% imo
