200NL: how did villain play this hand?

[Montezuma21]

Hero is TAG.

In villain's shoes i usually bet this turn and only check behind if the board is super dry but this hand got me thinking that maybe checking behind on semi-wet boards might be the best play. (obv. betting the turn here (in villain's shoes) would be standard if the turn were a 7 [img]/images/graemlins/diamond.gif[/img]), though feel free to disagree.
