patzer2: Here's my look at the game and today's Saturday puzzle (27. ?) with the chessgames.com Opening Explorer (OE) and Deep Fritz 14 x 64:<1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bg5 e6 7. Qd2 a6 8. O-O-O h6> This is the second most popular option in the OE. The most popular move is 8...Be7 as in Short vs Kasparov, 2015.
<9. Be3 Bd7> The popular move is 9...Be7 as in Junior vs Loop, 2007.
<10. f3 Qc7> The popular move is 10...b5 as in
S Zhigalko vs U Eliseev, 2013.
<11. g4 Ne5 12. h4 b5 13. Rg1 h5?!> This is the only move in the OE with 13...h5? And rightly so as it allows White to take the initiative with advantage after 13..h5? 14. g4
to
.
Instead, Black can hold with 13...b4 as in
Lahno vs D Kononenko, 2003.
<14. g5!> With this strong move, White begins to take control of the game.
Less strong is <drunkenknight>'s 2002 suggestion 14. gxh4 when Fritz indicates play might continue 14...Nxh5 15. f4 b4 16. Ncb5! axb5 17. fxe4 Rxa2 18. Kb1 Ra8 =.
<14...Ng8 15. Be2 Rb8 16. f4 b4 17. Nb1 Ng4 18. Bxa6 g6 19. Rgf1 Nxe3?>
This allows White a strong advantage.
Instead, Fritz indicates Black can hold with 19...Ne7 when play might continue 20. Bd3 Nxe3 21. Qxe3 Qb6 22. Qf2 Bg7 23. Nb3 Qc7 = (+0.21 @ 21 depth, Deep Fritz 14).
<20. Qxe3 Ne7 21. f5!> This pawn push gives White a strong attack.
<21...gxf5 22. exf5 e5> Not 22... exf5? when play might continue 23. Nxf5 Rb6 24. Be2 d5 25. Nxe7 Bxe7 26. Rxd5 Rd6 27. Re5 Re6 28. Rxe6 Bxe6 29. Bb5+ Bd7 30. Qd4 Rf8 31. Qd5 Bxb5 32. Qxb5+ Qd7 33. Qb8+ Qd8 34. Qb7 Qd7 35. Qa8+ Qd8 36. Qe4 Qd6 37. Rd1 f5 38. Qf3 Qe6 39. Qxh5+ Rf7 40. Nd2
(+6.69 @ 21 depth, Deep Fritz 14 x 64).
<23. f6> Here Fritz prefers the winning alternative 23. Nd2! when play might continue 23... Rb6 24. Bc4 d5 25. Bb3 exd4 26. Qxd4 Rh7 27. f6 Ng6 28. Qxd5
(+3.57 @ 20 depth, Deep Fritz 14).
<23... exd4 24. Rxd4 Be6 25. fxe7 Bg7 26. Re4 Qa5 27. Rxe6!> This solves today's Saturday puzzle. I found it but my follow up was not as strong as the game continuation.
<27...Qxa6 28. Rxf7
> (+11.46 @ 21 depth, Deep Fritz 14).
This is the strongest follow up, but white also wins with 14. Qf4, 14.
Qf3 or 14. Qf2.
My follow up solution was 28. Qf4 which wins after 28...Qxf1+ 29. Qxf1
fxe6 30. Qa6 Kf7 31. Qxd6 Rhe8 32. Nd2 Rb7 33. g6+ Kg8 34. Ne4 Rbxe7 35. Qxb4
(+5.07 @ 20 depth, Deep Fritz 14).
<28... Kxf7 29. e8=Q+ Rbxe8 30. g6+
Kg8 31. Rxe8+ Bf8 32. Qe6+ 1-0>
Black resigns as it's mate after 32...Kg7 33. Qf7+ Kh6 34. Re6 Qf1+ 35. Qxf1 Be7 36. g7+ Kxg7 37. Rxe7+ Kg6 38. Qf7+ Kh6 39. Qg7#.
