Grivas on Ding-Gukesh 10–12

12/10/2024 – The tenth game was nothing more than a boring draw, but games eleven and twelve were quite exciting as the two opponents traded wins to keep the score at 6-6 with two classic games left (after the third day off). Ding Liren played the eleventh game miserably (although he missed some good chances), while Gukesh D. lost the twelfth game without any real fight! The match seems to be quite balanced and nobody can make any predictions. There are plenty of mistakes made by both opponents and although the quality is low, the fighting spirit is high! | All photos by Eng Chin An.

Grivas on Ding-Gukesh games 7-9

12/6/2024 – After the second rest day, three draws followed in the FIDE World Championship 2024, making the match score 4½-4½. D. Gukesh missed good chances to prevail in games seven and eight, while game nine was probably the ‘quietest’ and most ‘correct’ game of the championship. We are entering the dangerous zone, where every mistake counts double, as there are only six games remaining. The general feeling by now is that D. Gukesh has lost more chances to take the lead than his opponent, and he is fighting more (even sometimes unjustifiably) to take the initiative. My takes. | All photos by Maria Emelianova

Learning the Shirov Killer

11/22/2024 – There are tactical motifs which are continuously repeated and can be learned exactly like we learn opening theory. I feel that the correct approach is to collect thematic, nearly identical positions which are involved on similar patterns which you should look for. In this survey I will present an often met tactical motif I call the "Shirov Killer." It was wonderfully demonstrated by legendary GM Alexei Shirov in an Internet blitz game.

On the other hand he could see tactics and combinations far in advance, so he went about countering them before even his opponents smell anything!
