Opportunity

When a tactical opportunity presents itself, seize it. Perhaps Black thought that he won a pawn with 33...Nxf2. This position arose in Miroshnichenko -- Rychagov, Sochi 2005. I found the game while exploring options for Black in the Catalan after 6.Qc2 dxc4 7.Nbd2, which scores very well for White.
