Amazing "GM Jan-Krzysztof Duda"

06/08/2021 – Beating the likes of 3 Super GMs (Grischuk, Gujrathi, Karjakin) and the current world champion (Carlsen) is such a feat. Newest World Cup 2021 Champ GM Jan-Krzysztof Duda is “no doubt” a contender to the World Championship Title. His style is solid (Karpov like) with deep theoretical knowledge and very calm.

But the highlight of this story remarkably his game against GM Sergey Karjakin showed mastery and brilliance to refute the Queen’s Gambit – Semi Tarrasch variation.

Now, let us check why the white bishop can become a powerful piece to win a game.

Queen’s Gambit  – Semi-Tarrasch Variation:   The aim of playing 4…c5, aiming a flexible and open game. However, the d5 pawn can become a weakness due to being isolated pawn. It is a matter of time, pawn will fall and the game with the help of a powerful white bishop.

9.     Rd1     Nc6
10.   Qa4     Be6    (Best square for the Queen)

12.   Bxf6    Bxf6
13.   Nxd5   Bxd5  (d5 pawn is out)

14.   Rxd5   Bxb2  (Compensate for the d5 pawn but its meaningless due to incoming disaster)

White is advantageous here due to the following reasons:

  1. Rooks control the file.
  2. d7 square is the  landing square for rook.
  3. Bishop at d3 is eyeing f7 pawn.
  4. The bishop at f6 has no threat and can’t prevent white from attacking.
  5. White king is at the center

19.              Nb8   (frustration)
20. g4        h6      (g6 is better)

27.    Bd5    (I want you to analyze this position, how nice white’s position. What can black do here? The white bishop is POWER….
