100nl: Continue this semi-bluff on the turn OOP with double-gutshot?

[BlackAMEX]

Villian is 65/26/2

Is a turn lead good in this situation, or is a check-call preferred? Does anyone check-fold?

The basis for my turn lead was that I wanted to continue the semi-bluff to hide my hand (obv...), but in retrospect I see that the board pairing was probably not the best thing to happen to me.

Thoughts?
