5/10NL Hand v. AJo

[Chazbot2000]

What kind of nothing could this guy rationally have after calling your preflop raise cold?

Similarly, what kind of jack could he have after calling your raise? KJ? Even that is quite loose. He definintely didn't play this like he had a killer hand like AJ (unless he's really crafty at representing a weak hand).

Oh, AK for a split pot seems reasonable too.

What DID he actually have? I give up trying to guess this.
