| May-04-17 | | patzer2: Here's my look at today's puzzle (25. ?) and game with the opening explorer, Deep Fritz 15 and Stockfish: <1. d4 f5 2. Nc3 Nf6 3. Bg5 e6> The popular move and my preference here is the more active 3... d5 as in Black's win in Dinstuhl vs Denis Gretz, 2016 <4. e4 fxe4 5. Nxe4 Be7 6. Bxf6 Bxf6 7. Nf3> This is the relatively more quiet and popular move. The second most
popular option and the computer preference is the more active choice 7. Qh5+ as in the White win in
V Popov vs A Neiksans, 2000 <7... b6 8. Bd3 Nc6 9. c3
Bb7 10. Qe2 O-O 11. O-O-O a5 12. h4 Ne7 13. Nfg5 h6 14. f4 Nf5?!>  to  (-1.50 @ 28 depth Komodo 10.3). This appears to be the decisive error. Black's practical OTB survival chances are surelty better with
the computer suggestion 14... Bd5 15. Nh7! Kxh7 16. Nxf6+ Kh8 17. Nxd5 Nxd5 18. g3 c6  (+1.03 @ 32 depth, Stockfish 240813) <15. g4 Nd6 16. Nh7 Rf7 17.
Nhxf6+ Rxf6 18. Nxf6+ Qxf6 19. Rhf1 Qxh4 20. c4 Rf8 21. c5 Ne8 22. f5 exf5 23. Rxf5 Nf6 24. Rdf1 Bd5 25. Rxd5!> This solves the Thursday May 4, 2017 chessgames.com puzzle. <25...Nxd5 26. Bh7+ Kxh7 27. Qe4+> This wins, but also decisive is 27. Rxf8 Qg5+ 28. Kb1 Qg6+ 29. Qc2 Qxc2+ 30. Kxc2 Ne3+ 31. Kd3 Nxg4 32. cxb6 cxb6 33. Rb8 Nf2+ 34. Ke2 Ne4
35. Rxb6  (+3.59 @ 20 depth, Deep Fritz 15)
<27... g6 28. Rxf8 Qg5+> If 28... Kg7, then White wins after 29. Rb8 Qg5+ 30. Kb1 Ne7 31.
Re8 Kf7 32. Rh8 Kg7 33. Rd8 Qf6 34. Qe5 bxc5 35. Rxd7 Kf7 36. Qxf6+ Kxf6 37. dxc5 (+4.02 @ 22 depth, Deep Fritz 15) <29. Kb1 Kg7 30. Qe8 1-0> (mate-in-seventeen, Deep Fritz 15 @ 21 depth) |

| May-04-17 | | Iwer Sonsch: 25.Rxd5 Nxd5 (forced) 26.Rxf8+ Kxf8 27.Qe3+ Ke7 or e8 28.Qxd5 Qe1+ 29.Kc2 Qf2+ 30.Kb3

Now 30...Qe3 or Qg3 falls to 31.Qe5+, and White wins with superior material. Too easy for a Thursday, and so, the move I overlooked was 27...Nf6. |
|
| May-04-17 | | thegoodanarchist: 25.Rxd5! causes Mahmoody Blues |
|
| May-04-17 | | Iwer Sonsch: <<patzer2> 28...Kg7 29.Rb8> is indeed winning for White, but offers Black a variety of defensive options: <29...b5> threatens perpetual check after 30.Qxd5?. White wins with 30.Qe5+ Qf6 31.Rxd5 (3.41 @depth 26). That's why White has played 29.Rb8!. <29...Ne7> keeps the black queen at h4 and the white queen at e4. White wins with 30.Rd8 bxc5 31.Rxd7 Kf8 32.dxc5 (3.58 @depth 25). |

| May-04-17 | | saturn2: I was thinking of something else 25 RxNf6
if 25 ..RxN 26 Qe8
if 25.. gxR 26 Qe7 Bf7 27 Bh7+ |
|
| May-04-17 | | Iwer Sonsch: <saturn2> Your line is -0.65 @depth 27 after 27...Kg7. White doesn't have anything particularly interesting. After 27...Kxh7, 28.Qxf8 Qg5 29.Kb1 Qd5 30.Rxf6 is the only line preventing a clear disadvantage for either player, and leads to perpetual check for Black. |

| May-04-17 | | Walter Glattke: saturn2: 25.-gxR 26.Qe7 allows 26.-Qg5+

| May-04-17 | | King Harvest: Ugh. Missed the Bh7 sac.
Quick Q. Help me out, kibitzers... I'm trying to remember the name (and favorite openings) of a minor master (I believe a european, german or dutch perhaps) active roughly mid-twentieth century iirc -- who was known for championing extremely aggressive and entirely dubious openings that he used to create some spectacular games against other second tier players. His combos have been featured on the POTD years back -- which is where first encountered him. The name escapes me. Any help? |

| May-04-17 | | agb2002: White has a rook for a knight and a pawn.
Black threatens Bxa2 (Qxg4 loses to Qxg4).
White can exploit the weak light squares around the black king with 25.Rxd5 Nxd5 26.Bh7+ Kxh7 (26... Kh8 27.Rxf8+ Kxh7 28.Qe4+ g6 29.Rf7+ Kg(h)8 30.Qe8#) 27.Qe4+ A) 27... g6 28.Rxf8

A.2) 28... c6 29.Rf7+ Kg(h)8 30.Qe8#.
A.3) 28... Qg5+ 29.Kb1
A.3.a) 29... Kg7 30.Qe8 Qe7 (30... h5 31.Qf7+ Kh6 32.Rh8#) 31.Rg8+ Kh7(f6) 32.Qxg6#. A.3.b) 29... Nf6 30.Qe7#.
A.3.c) 29... h5 30.Qe8 Qe7 (30... Qxg4 31.Rh8+ Kg7 32.Qf8#; 30... Kg7 31.Qf7+ Kh6 32.Rh8#) 31.Rf7+ wins. B) 26... Kg8 27.Qxd5+ and White ends up a rook ahead. C) 26... Rf5 27.Qxf5+ and Qxd5 as in B.
D) 26... Kh8 27.Rxf8#. |

| May-04-17 | | swclark25: I went exactly with <Iwer Sonsch> 25.Rxd5 Nxd5 (forced) 26.Rxf8+ Kxf8 27.Qe3+ Ke7 or e8 28.Qxd5 ... White has Queen & Bishop. Black only Queen. |
|
| May-04-17 | | swclark25: Just noticed <Iwer Sonsch> last comment about 27)...Nf6
Guess I need to find a way around that! |
|
| May-04-17 | | Walter Glattke: Glattke Code A 74 descrives the Blackmar-Doemer
Gambit of Diemer as "Schneiders-Angriff im Lemberger Gegengambit" with the only real dangerous attack: 1.d4 d5 2.e4 dxe4 3.Nc3 e5 4.Qh5 ed4 5.Bc4 Qe7 this is the only move to win for black.
6.Nd5 Nf6! 7.Nxe7 Nxh5 8.Nxc8 Nc6 or "Golden Nugget Variation with 6.Bg5 Nf6 7.Bxf6 gxf6 8.Nd5 Qd6! I call this as blackjack Gambit, Diemer played many Matches against weak enemies, had no Chance against gransmasters, he was not strong enough to beat them. |

|
| May-04-17 | | swclark25: Found <Walter Glattke>'s first kibitz of the day...
White also wins with 29.-Qe7 30.Qxe7+ Nxe7 31.Rf7+ or 29.-Ne7 30.Rf7+ Kg8 31.Qxe7, but no win with 26.Rxf8+ Kxf8 27.Qf3+ Nf6, 26.Bh7+ necessary. Even though I got 25.Rxd5, I thought 26.Rxf8+ would also work :( |
|
| May-04-17 | | Walter Glattke: 26.Rxf8 not more than draw or after
26.-Kxf8 27.Bg6 Qg5+/27.Qg4 Nf6/27.Bc4 Nf6/27.Bf5 Nf6 :( |
|
| May-04-17 | | Walter Glattke: Corr 27.Qg4?/27.Qe4 Nf6 |

| May-04-17 | | tivrfoa: what about 25. Qe7? |
|
| May-04-17 | | Iwer Sonsch: <tivrfoa> 25...Bf7! 26.g5 Qxd4 27.Bc2 hxg5 holds (0.75 @depth 23). |
|
| May-04-17 | | Walter Glattke: 25.-Bf7 26.Rxf6 gf6 27-Rxf6 Qg5+ 28.Kb1
