call this flush?

[ipokeder]

villian in this hand seems terrible. his stats are like 35/10/1.25, but more importantly i saw him coldcall an rr in the blinds with 6Ts, but i haven't played enough hands with him to have much of a read on how he plays. he has not been ridic aggro type of tard though, i think more of station doesn't fold type. do i call this?

ipokeder:

i guess it's plausible that he could have 46 and for some reason or another decide to play it this way, or maybe 57/77 but it'd be REALLY weird i think...

thoughts?
