patzer2: Entertaining game by the then 15-year-old Italian Master Guido Caprio:<1. a3> The Anderssen Opening is seldom seen in Master play as theory indicates Black equalizes too easily. However, it was successful against the strongest player in the world in it's debut in Anderssen vs Morphy, 1858 and is occasionally trotted out in blitz games by some of the top players in the world.
<1...e5> This is the most popular reply in the chessgames.com
Opening Explorer. Other good replies includes 1...d4 as in I A Nataf vs R Wojtaszek, 2014, 1...g6 as in Velimirovic vs Timman, 1978, 1...c5 as in E Ambrus vs Balashov, 2001 and 1...Nf6 as in Carlsen vs Ivanchuk, 2010
<2. c4> White goes for a reverse Sicilian hoping the
extra tempo with 1. a3 will prove useful.
<2...Nf6> Black accepts White's invitation to play a reverse
Sicilian.
<3. d3> More popular are 3. Nc3 as in
Carlsen vs Eljanov, 2010 and 3. e3 as in Nakamura vs Wang Hao, 2013.
<3...d5> An alternative is 3.
..Nc6 as in Pandix vs Rybka, 2009
<4. cxd5 Nxd5 5. Nf3 Nc6 6. g3> It's looking like a reverse Sicilian Dragon with White having an extra tempo.
<6...f6> Also good is 6...Be7 as in
T Kabos vs H van der Poel, 2009
<7. Bg2> The game appears to leave the opening book as this is the only contest in the opening explorer with this move.
<7...Be6 8. Nc3 Qd7 9. O-O O-O-O> Black has completed development and fully equalized.
<10. Bd2 h5> Here I prefer the computers suggestion 10...g5
(-0.58 @ 26 depth, Stockfish 080716) with good attacking chances for Black.
<11. h4 Bh3> This allows White full equality. Better might be the computer pick 11...Nxc3 = to
.
<12. Nxe5 !?> With this bold sacrifice White exchanges his Rook for a Bishop plus a Pawn and a bit of an initiative.
<12...fxe5 13. Bxd5 Bxf1 14. Qxf1 Kb8> Here the computers prefer 14... Nd4 15. Bc4 Kb8 =.
<15. Be4 Nd4 16. Qd1 Be7 17. Nd5 Bf6 18. Rc1 c6 19. Nb4 Qg4 20. Kf1 Rhf8 21. Be3 g5?> This is the losing move. Instead, 21...Qh3+ 22. Bg2 Qe6 = keeps it level.
<22. Bxd4>
(+7.00 @ 20 depth, Stockfish 7) White is clearly winning.
<22...exd4> If 22... Rxd4, then 23. Nxc6+ bxc6 24. Qb3+ Kc7 25. Rxc6+ Kd8 26. Qb8+ Ke7 27. Qxa7+ Rd7 28.
Qc5+ Kf7 29. Rxf6+ Kxf6 30. Qxf8+
(+5.78 @ 20 depth, Deep Fritz 15).
<23. Nxc6+ bxc6 24. Qb3+ Kc7 25. Rxc6+ Kd7 26. Qb7+ Ke8 27. Bg6+> Black resigns in lieu of 27...Rf7 28. Qxf7# 1-0
