With ambitious and strong play, he has already beaten the likes of Gelfand and Sutovsky, not to mention draws with Nakamura and MVL. Now he faces the always dangerous ex-world champion Veselin Topalov} 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 {Topalov goes for the most principled line, instead of the currently fashionable 6.d3!?, which leads to quieter positions.} b5 7. Bb3 d6 8. c3 O-O 9. h3 {This position has been played almost 37.000 times according to my database! Black has a wide variety of choices in this main Ruy Lopez variation.} Na5 10. Bc2 c5 11. d4 Nd7 $5 {an interesting line, that has been played by David Anton himself three rounds ago against Sutovsky. White now has two choices: a closed position with 12.d5 or a very double-edged fight after 12.Nbd2. Naturally, both Sutovsky and Topalov went for the second option, always leading to interesting play} 12. Nbd2 (12. d5 $5 {is more positional, and was played in the very first time in a classic Fischer - Keres game, from the amazing Candidates Tournament in Curacao,1962!} Nb6 13. Nbd2 {is the main move} (13. g4 $6 {The brilliant ex-world champion went for a dubious plan here, white normally has to be better prepared to build this kind of idea on the K-side (normally with Nbd2-Nf1-Ng3). It is also clear that Fischer wanted to stop f5 hitting his strong central pawn on e4, but on the other hand he allows h5!} h5 $1 14. Nh2 hxg4 15. hxg4 Bg5 {suddenly black has easy play exploiting the weak squares, and still keeps good prospects on the Q-side} 16. Nd2 g6 17. Ndf3 Bxc1 18. Qxc1 Kg7 19. Qg5 {the endgame is no relief for white, but black was considering Rh8 and then start some work on the K-side himself.} Nb7 20. Qxd8 Rxd8 21. a4 bxa4 22. Bxa4 Nxa4 23. Rxa4 Bd7 24. Ra2 c4 25.

In case of 14.Nf1, black can simplify on d4 and enjoy a good initiative in exchange for the worse pawn structure.} 14. d5 (14. Nf1 $6 cxd4 15. Nxd4 Nxd4 16. Qxd4 Ne5 { justifying the 11...Nd7 move} 17. Qd1 Bf6 18. Ne3 Be6 $11 {this is a typical position where the piece activity easily compensates the weak pawn on d6. Black has easy play, with moves like Rc8, Nc4, and Qb6. Meanwhile, white has a hard time developing his Q-side, and moves like f4 will create weaknesses.} 19. Bd2 (19. f4 Nc4 $132) 19... Nc4 20.

A superb win from David Anton, the man of the hour, going into the last round as the sole leader of the 2017 Gibraltar Masters! In the last round, he faces the experienced super-GM Michael Adams.} 0-1
