May-17-18 | | ChessHigherCat: Rook sac Thursday!
21...Rxf2+ 22. Kxf2 Rf8+ 23. Ke1/e2/e3 Qg3 threatening Rf2 or Qxg2 and black has gotztabe got |
|
May-17-18 | | ChessHigherCat: Would you believe 21...Rxf2+ 22. Kxf2 Qg3+ immediately? I guess the lesson there is to go with the most forcing variant. |

 | | sorokahdeen: Was this a speed game? |
|
May-17-18 | | Walter Glattke: 21.-Rxf2+ 22.Kxf2 Rf8+? 23.Ke2 Qg3+ 24.Be3, queen guarded, white wins. |
|
May-17-18 | | weary willy: Looks like he was Dutch, but played for Ghana at the Dresden Olympiad |
|
May-17-18 | | agb2002: Black is one bishop and one pawn down.
The rook on e6 is defenseless. This suggests 21... Rxf2+: A) 22.Kxf2 Qg3+
A.1) 23.Ke2 Qg4+
A.1.a) 24.Ke1 Qxe6+ 25.Qe2 Qxg6 - + [n vs P].
A.1.b) 24.Kd2 Bf4+ 25.Ke1 (25.Kc3 Qxd1 wins decisive material -26.Bxf4 Qxa1-) 25... Qxe6+ 26.Qe2 Bg3+ 27.Kd1 Qxg6 - + [n vs P]. A.2) 23.Kf1 Rf8+ 24.Qf3 (24.Ke2 Rf2+ 25.Ke1 Rxg2+ 26.Kf1 Qf2#) 24... Rxf3+ 25.gxf3 Qxf3+ 26.Ke1 Bg3+ 27.Kd2 Bf4+ 28.Ke1 Qg3+ A.2.a) 29.Kd1 Qg4+ 30.Re2 Bxc1 31.Rxc1 (31.Bxh5 Qxh5 32.Rxc1 Re8 wins) 31... Qxg6 - + [q+n vs 2R+P]. A.2.b) 29.Ke2 Qg4+ 30.Kd3 Qxe6 - + [q+n vs R+B+P] (31.Bxf4 Qxg6). A.2.c) 29.Kf1 Qh3+ as in A.2.b.
B) 22.Ke1 Qg3 23.Re3 Qxg2 wins. |
|
May-17-18 | | Cybe: Much better 24. Kd2 (Bf4+, Kc3, Q:d1, B:f4, Q:a1, R:c6+, Kb7, Rc7+). |
|
May-17-18 | | cocker: 20 Bxh5 would have given White the advantage. Apart from the winning move, not a very high standard game. |
|
May-17-18 | | SpamIAm: Agreed, <cocker>. There's some strange weak moves from both sides throughout the game. |
|
May-17-18 | | malt: 22...R:f2+ 23.K:f2 Qg3+ 24.Ke2 Qg4+ 25.Kd2 Bf4+
26.Re3 B:e3+ 27.Ke1 Qg3+ 28.Ke2 Qf2+ 29.Kd3 B:d4
29.Qe2 Ne5+ wins
22...Rf2+ 23.Ke1 Qg3 24.R:c6+ Kb8 24.Qd3 Rf3+ |
|
May-17-18 | | takchess: The Rook Sack was my only candidate move. For some reason, saw the followup queen check skewer and took the loose rook not the Queen. I feel like I would of found this OTB . Whites pieces are badly uncoordinated. Not bad for a Thursday. |
|
May-17-18 | | Wiley: Ouch, talk about decimation! Reminds me of the Monty Python skit when the knight had all his limbs chopped off and still insisted on fighting... |
|
May-17-18 | | Cheapo by the Dozen: Yep. This is one of those puzzles where you look a few moves ahead, realize you'll surely have an advantage, and then recalculate how big you can make it after a couple of moves have been played. |
|
May-17-18 | | gofer: Well, the rook sac is obvious, but not the follow up... <21 ... Rxf2>
22 Ke1 Bg3 +-
I think this the best continuation. It sets up a horrible pin that white
is going to find very difficult to break. One continuation is... 23 Re8+ Rxe8
24 Bxe8 Nf6!
Rather than wasting the wonderful pin immediately, for a lousy bishop (Rxf8+)
black threatens Qe7+ mating!!! From here it all looks horrible for white. <22 Kxf2 Qg3+>
23 Kf1 Rf8+
24 Ke2 Rf2+
25 Ke1 Rxg2+
26 Kf1 Qf2#
<23 Ke2 Qg4+>
24 Kd3? Qxd1+ +-
<25 Kd2 ...>
Like <Cybe> says, I think black should avoid the following... 25 ... Bf4+
26 Kc3! Qxd1
27 Bxf4 Qxa1
28 Rxc6+ Kb7
29 Rb7+!
and play an <intermezzo> putting the white king on a bad square <25 ... Bf4+>
<26 Kc3! b4+>
27 Kb3/Kc4 Qxe6+ (winning the rook and bishop) +- <27 Kxb4 Qxd1>
<28 Bxf4 Qxa1>
<29 Rxc6+ Kb7>
<30 Rc7+! Kb6>
Now the knight is safe!!!!
31 Rxd7 Qxb2+
32 Ka4/Kc4 Qb5+ -+
31 Ka3/Kb3 Qf1 -+
31 Kc3 Qe1+ -+ |

May-17-18 | | hdcc: "Not Ghana win". |
|
May-17-18 | | saturn2: I sorted out 22..Rf8 and took 22...Qg3 |
|
May-17-18 | | dumbgai: Wow what a slaughter. White loses his entire army. |
|
May-17-18 | | patzer2: Not too difficult to calculate that today's Thursday solution was 21...Rxf2+! 22. Kxf2 Qg3+ -+ with a crushing attack. White had a big and likely winning advantage coming out of the opening, but it greatly shrunk after 14. Kf1?! ± (+0.97 @ 18 ply, Stockfish 9 analysis of move 14...?). Instead, 14. Kh1 ± to +- (+1.94 @ 18 ply, Stockfish 9 analysis of move 14.?) would have given White a near decisive advantage. |
|
May-17-18 | | Mayankk: Wasn’t the real puzzle move 20 ... Nxf2 instead of 21 ... Rxf2+? What else can Black play as 21st move? There seem to be no other candidate moves given Black has already sacrificed a knight and is compelled to go on a full-on attack. All in all a bad Thursday puzzle. |
|
May-17-18 | | njchess: There are actually two puzzles here. First, what is Black's follow-up to the obvious 21. ... ♖xf2+ 22. ♔xf2? I had ♖f8+ or ♕g3+. I settled on ♕g3+ because that left White's queen en prise after 23. ♔e2 ♕g4+. The second puzzle is, why did White take so long to resign?! After 24. ... ♕xd1+, surely he must have realized that all was lost. |
|
May-17-18 | | petemccabe: Can anyone explain why white played on after losing his queen? Nothing that follows seems to indicate any sort of plan to overcome this deficit. And why on earth would you give up the last rook and then resign? Why not just resign? I'm just a 1500 player but this baffles me. |
|
May-17-18 | | patzer2: White's decisive mistake was grabbing Black's poisoned pawn with 20. Rxe6?, allowing 20...Nxf2! -+. Instead, 20. Bxh5! ± (+1.11 @ 21 ply, Stockfish 9 analysis of move 20.?) would have left White with a clear advantage. |

 | | Willber G: <Walter Glattke: 21.-Rxf2+ 22.Kxf2 Rf8+? 23.Ke2 Qg3+ 24.Be3, queen guarded, white wins.> 23...Qg3 is not check if the K is on e2. |
