I don't think Crazy is thinking about range. If Crazy isn't normally the type to jam a 4th bet in light then this is a strong indicator he is ready to go.There are two other players at the table who know what "range" is and actually use that information - MP2 and Crafty. Crazy Jr. doesn't think much about ranges, image, what someone else might be representing.

Honestly at this point I feel like this is an instafold for me, but your threads are usually pretty deep so I'm afraid I am missing something.
