Marshall Attack in World Cup 2021

GM Carlsen advanced to Semifinals
31/7/2021 – Fantastic performance by World Champion Magnus Carlsen in winning both games versus GM Bacrot, Etienne (France) in the quarterfinals. I have noticed his deep understanding of the Marshall Attack as demonstrated in his fantastic “queen sacrifice” game.
To chess beginners, let me introduce you to “The Marshall Attack” which is a theoretical contribution of legendary US GM Frank Marshall.
GM Etienne Bacrot used the Anti-Marshall Attack variation 8. a4, unfortunately, it was refuted by GM Carlsen’s flawless execution as shown in his game.
Ruy Lopez – Marshall Attack: This variation teases white to take the 8…d5 pawn in return to quick development at the same time, and aims to attack white’s kingside. It is a gambit but white must think twice to accept it because it’s dangerous and tricky.

COMPARE IT TO GM CARLSEN's GAME

At move 8, GM Bacrot played 8. a4 (anti-marshall) instead of the normal 8. Re1. But the anti-marshall setup did not materialize because of GM Carlsen's genius deviation.

At move 14... d5, Marshall Attack is activated. Its up to GM Bacrot to accept the poison pawn at e5. Notice the white's bishop at a2 will become a useless piece.


Now, analyze the position why white is in danger here. The way GM Carlsen combines his tactical genius and his exemplary skill to dissect the smallest weakness of opponents position, justifies why he is very difficult to be dethroned as world chess champion.
