His latest abominations against routine come from the just-completed Russian Cup, where he lost in the finals 1.5-.5 to Artyom Timofeev. In the semi-finals, against Tomashevsky, he trotted out the hoary old King's Gambit, while against Timofeev in the finals it was time for the Schliemann. Of course neither of those choices is as rare as his patented 2.Na3, but they're still both extremely rare at elite levels.
Have a look.
