Game of the Week #684

Germany's highest-rated star Vincent Keymer is in top shape at the moment, leading the Chennai Grandmasters with 5½ out of 7 points, with a performance that allowed him to enter the top 10 in the live world rankings.

In our Game of the Week, Keymer adds 1.e4 to his repertoire, based on super deep and sharp preparation. It looks like this took Karthikeyan Murali by surprise, allowing Keymer to produce a nice attacking game.

Warm-up question: What would you play here with White?

This week's show

In this opening Black opts for active piece play and is not afraid to fight for the initiative from an early stage. One of the many good features of this opening is that Black is often the side which controls the pace of the game.
