The Sveshnikov Variation of the Sicilian Defence is considered one of the most promising replies to 1.e4, often giving rise to sharp and complex positions which require precise and inventive play from both sides. Thus, an opening tailor-made for Alexei Shirov (FIDE World Cup finalist in 2007), who has included it into his repertoire with both White and Black and knows the mutual tricks and traps all too well.


Game of the Week 365

Ideas and strategies in Grandmaster games can be quite instructive. IM Merijn van Delft presents games like these every Wednesday. On this week's show:

As so often, there are several interesting chess tournaments being played at the same time. Norway Chess has just started with a new tournament format (armageddon in case of a draw) and before that Magnus Carlsen won the Lindores Abbey Chess Stars rapid event. Meanwhile, the ladies are playing their Candidates Tournament. But the game that stands out most to me this week is a game between Nico Zwirs and Sipke Ernst, two friends of mine, played at the Groningen weekender.

The live show is free to watch, and available on-demand for ChessBase Premium accounts.

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