The Carlsbad construction is as well-liked as ever. Regardless that the plans for play in it are well-known, fashionable observe regularly introduces novel concepts. One in all them, for instance, is that the transfer …h6, identified to be imprecise for a really very long time, is actually fairly acceptable for Black.
One other thought, this time for White, was a refinement of Botvinnik’s plan identified from the classical recreation Botvinnik-Keres, USSR Championship 1952.
Within the following place, which arose within the latest recreation Vidit-Kryvoruchko, performed on the European Membership Cup in Austria in 2022, it was White’s flip to maneuver.
We see that Black has performed the transfer …h6, beforehand thought imprecise (as a result of now Black can’t play the everyday maneuver …Nf8-g6; nevertheless, Black has different concepts like …Nh5 now). White is able to implement Botvinnik’s plan with Qc2, f3, and e4, however earlier than doing any of that he performed the very stunning transfer 11.a4!?
That is stunning as a result of it kills off White’s different plan on this place; the minority assault on the queenside. Nevertheless, White gamers have found two issues: 1. Black’s plan to increase with …b5 and …a5 after which create play on the queenside is kind of viable (as within the case of the speedy 11.f3 b5); and a pair of. Increasing on the queenside with a5 makes White’s centre growth even stronger, plus it permits for the maneuver Nc1-b3-c5.
I’m fairly positive that such a transfer would have by no means crossed Botvinnik’s thoughts.
Within the recreation, Vidit applied White’s technique completely. He superior the pawn all the best way to a6 after which switched consideration to the middle and the kingside.
Right here he performed the transfer 20.g4!, additional squeezing Black. Kryvoruchko didn’t wish to keep passive with 20…Bc8 21.Nd3 when White can proceed getting ready the advance on the kingside, and lashed out with 20…Bxg4?! 21.fxg4 Nxg4, however after the exact 22.Bh3! Nxe3 23.Nd3 White was in management and gained the sport.
