Rameshbabu Praggnanandhaa, India’s rising young star, at 15, ran away with the top prize at the Julius Baer Challengers Tour. Praggnanandhaa’s play has the compulsiveness of youth with attending thirst for complications. He is not afraid to mix it up. Witness the following game where he excels in tactics.

King’s Indian Defense

1. d4      Nf6 

2. c4       g6

3. Nc3    Bg7 

4. e4      d6 

5. Nf3    O-O 

6. Be2    Nbd7 

6....e5 7. 0-0 Nc6 transposes into the popular Classical Variation of the KID..

7. O-O   e5

8. Be3    ....

This is known as the Gligoric System named after the famous Yugoslav world contender Svetozar Gligoric. The text allows White to maintain tension in the center.

8....        c6 

9. d5      c5 

After 9.....cxd5 10.. cxd5 Nh5 11. Re1 Ndf6 12. h3 Nf4 13. Bf1, White is slightly better because of his Q-side prospects.

10. Ne1 Kh8 

11. g4    Ng8 

12. Qd2 f5 

13. gxf5 gxf5 

14. exf5                ....

Seems premature as it opens up the f file to Black’s army. A safer alternative is 14. f3, i.e., 14....f4 15. Bf2 Ndf6 16. Kh1 Nh5 17. Rg1 Bh3 18. a3 Qc8 19. b4 b6 20. bxc5 bxc5 21. Nd3 Qd7 22. Bh4 Bf6 23. Bxf6 ch Ngxf6 24. Nf2, and White has a good game.

14....      Ne7 

15. Kh1 Nf6 

16. Bd3 Bxf5 

17. Rg1  e4!

Now Black has more mobile pieces, and will activate his Knight bound for the vital e5 square.

18. Be2 Ng6 

19. Rg5  Qd7 

20. Nc2 Rf7 

21. Rag1               Raf8 

22. Qe1?!             ....

Not a good choice as the White Queen is badly placed here. Better is 22. Ne1, defending the square f3.

22....      Ne5! 

23. Qf1  Nf3 

24. Bxf3                exf3 

25. Ne1 Ng4!

The clincher with the immediate threat of 25....Nxe3 26. fxe3 f2!. followed by 27....Be4ch.

26. Bf4  Bd4!

Now Black’s pieces swarms on the Kingside, making life miserable for the poor White King.

27. Bg3  Rf6 

28. Nxf3?             ....

In a lost position, any move is bad. The text loses material.

28....      Bxc3

Here it’s time for White to resign as 29. bxc3 is refuted by 29....Be4. 

The rest needs no comment.

29. Nh4 Be4ch

30. f3     Rxf3 

31. Nxf3               Rxf3 

32. Qg2 Rxg3

0-1

*     *     *

Solution to last week’s puzzle:

White to play and win.

White=Kg1, Qd6, Re1, Bb3, Pa5, Pb4, Pd5, Pf4, Pg3, Ph4

Black= Kf7, Qc3, Bb7, Nf8 Pa6, Pe4, Pf5, Pg6, Ph5  

1. Qc7ch!             1-0    

 If 1....Qxc7 2. d6ch Ke8 3. dxc7 Kd7 4. Rc1 and White wins.
