I have found the min-raise to be heavily weighted towards draws. In this example it would probably be the A
. Maybe it's tptk raising to ''see where he's at''. 2 pair is unlikely. Maybe he thinks he has to raise w/ a made non-nut flush but doesn't want to commit too many chips. Even fish wake up with the nuts sometimes too. Either way it's close.
