The Bernstein Defense Except Gligoric System variation.

6. Nf3, d5
7. 0-0, cxd4
8. exd4, dxc4
9. Bxc4, b6
10. Bg5, Bb7
11. Re1, Nbd7
12. Rc1, Rc8
13. Qb3 ....

White defends the c4 Bishop, attacks Black's Bishop at b4, and at the same time exerts more pressure on the e6 pawn.

13. .... Qe7
14. Bd5 ....

White neutralizes Black's control of the long diagonal, taking advantage of the pin on the Queen.

14. .... Ba6

White wins a piece after 14....Bxd6, 15. Nxd6 Qd6, 16. Nxb4 ....

15. Qa4, Bxc3
16. bxc3, Nb8
17. Bb3, b5
18. Qa5, Qb7?

Black desperately needed to remove the Queen out of pin.  If 18....h6, then 19. Bh4 g5, 20. Nxg5 hxg5, 21. Bxg5 and White still retains the pin.

19. Bxf6, gxf6
20. d5!! .....

A freeing move, which creates mobility for White's pieces.

20. .... exd5
21. Qb4, Qd7
22. Qh4, Kg7
23. Nd4, Resigns

White threatens 24. Re7 followed by Nf5+ with a blistering attack.

If 23....Rce8, then 24. Bc2 Rxe1, 25. Rxe1 (...h6, 26. Nf5+ ...) Rh8, 26. Nf5+ with renewed threats.  

Simply fantastic !
