By the time the games have been going for 2 1/2 hours, it will be time for me to leave the house, and my internet connection. Today is the eleventh annual Winterfest Scholastic chess tournament, an event that I created and run. As many as 143 young chess players have competed in this event in past years, although it will be much smaller today. By the time my event is over, the players in Wijk aan Zee will be asleep.

I played this variation of the Sicilian in the 1990s before switching to the Sveshnikov (4...Nf6 and 5...e5). Vladimir Kramnik played the Sveshnikov in his youth, but switched to more solid defenses when he started playing against the world's top players.
The Kalashnikov is similar to the Pelikan, which was a frequent choice of Louis-Charles Mahé de La Bourdonnais in his match with Alexander MacDonnell. In the Pelikan, Black plays 5...a6, which permits 6.Nd6. MacDonnell played 5.Nxc6, which is now considered a positional error, thanks to La Bourdonnais's terrific win in one game that every chess player should study.
The Kalashnikov would seem too risky for top-level grandmasters, but checking the database reveals a number of games. Garry Kasparov played it once in 1997. Vasily Ivanchuk and Teimour Radjabov both have played it on multiple occasions.
