Turn Bluff by Laurila?

Nível 3 : Blinds 100/300, 300 ante

On a board of Q♦9♥2♦3♥, Francois Vlassis had put out a bet of 1,800 only for Tero Laurila to announce a three-bet to 8,000.

After some thought Vlassis folded, flashing the Q♣ for top pair. Laurila showed his opponent the K♦ and raked in the pot.
