Another example from GM Vasily Ivanchuk.

Ivanchuk is currently leading the M-Tel 2008 tournament with 5/5, which is pretty incredible at the highest level. As mentioned in the previous post, he is one of the most creative 2700+ players.

Let's take a look at another tactical position from the game Ivanchuk-Kasparov 2002 (rapid). The aim is to train your tactical sense, albeit in a less spectacular way than the previous post. Let's mention that this game was a Sicilian Najdorf where Ivanchuk played 6 Rg1 !?, with the idea g4-g5. Kasparov has been the leading expert of the Najdorf for many years, but I am sure he spent more time on 6 Be3, 6 f4, 6 Bc4, 6 g3, 6 h3 than 6 Rg1, which was a clever attempt to take him off the beaten track as soon as possible. Finally let's mention that Nigel Short has played 6 a3 !? a few times, which is quite unusual too.

Try to find the best move in the following position. Good luck !

White to play and win
