|May-28-06|| ||jackmandoo: For some reason this puzzle today is way over my head.|
|May-28-06|| ||LIFE Master AJ: Here is the position ... with Black to play and make his thirty-ninth move. (Problem of the day, Sunday / May 28th, 2006.) |

A truly amazing move ... and it does not mean diddley if you don't find the follow-up.
This rejoinder is stunning ... GM Keene stated he might not have found it in a tournament game. (To be honest, I missed it completely.) The whole idea is based on the fact that White can never capture on g3 (with the King) as ...Qh4 mate is the refutation. (A simple epaullette mate.)
Now White must give himself an esacpe square ... as a mate is threatened on h4.
41.♖c1 fxg3+; 42.♔g1 ♕h4!;
The Knight is left hanging ... for one more move.
Once more, White must give his King an escape square.
<[Worse is 43.exf5?? Qh2+; 44.Kf1 Qh1#]>
43...♕h2+ 44.♔f1 ♕h1+ 45.♔e2 ♕xg2+; ( , White Resigns.)
<[If you need to see the win ... 45...Qxg2+ 46.Kd3 <(46.Kd1? Ne3+ 47.Ke1 Qf2#)> 46...Qxf3+ 47.Kc4 Qxe4+ 48.Kc3, <(But not: 48.Kb3?? Nd4+; forking King and Queen.)> 48...Nf6 49.Bc2 Qd4+ 50.Kb3 Qd2 51.Kb2, <(Worse is: 51.Rf1?? Nd4+; etc.)> 51...g2 52.Qd3 Qxc1+ 53.Kxc1 g1Q+ 54.Kb2 Bxb6 55.Qxf5 Qd4+ 56.Kc1 Qa1+ 57.Bb1 Be3+ 58.Kd1 Qd4+; and Black wins.]>
(I had my doubts about this one ...
so I subjected the final part to an intensive computer analysis. I apologize if I covered the same ground as anyone else.)
|May-29-06|| ||kevin86: Black throws\two pieces into the meat grinder. Instead,they act as a rib spreader to open the white position.|
Neat position of the shadow-y bishops at e1 and d8-guarding some of the same squares.
|Jun-02-06|| ||LIFE Master AJ: <kevin86> Agreed. (Nice comment.)|
|Nov-12-13|| ||MikhailGolubev: annotated in Chess Informant,
later - in the book "Understanding the King's Indian" (2006)
|Aug-30-15|| ||Penguincw: Woo hoo, it's Monday! Oh wait, it's Sunday, nvm.
So anyway, I want to move the knight and threaten mate on h4, but the bishop on e1 is being a _____, so I'm going to block him with the interference move, 39...Rg3. I got white's obvious response, but nothing more.
|Aug-30-15|| ||jith1207: After blitzing through first 5 days of the week, I got stuck in Saturday and Sunday puzzles. But I would take it any week. At least I'm getting to understand and learn various themes and positional understanding from them.|
Thanks to <CGdotCom> for churning out instructive puzzles, not just inexplicable genius-level puzzles for the tough days. Even if one cannot crack it, if one can learn something out of it to use in game situation, I think the purpose would be well served here.
|Aug-30-15|| ||diagonalley: <Penguincw>: me too!|
|Aug-30-15|| ||morfishine: Nice finish|
|Aug-30-15|| ||Ehrenfest: I missed the second blocking move. After 41. Be1 there follows 41.... Ng3, and white is defenseless against Qh4|
|Aug-30-15|| ||patzer2: White can turn the tables and win after 21. Nxa8 , which is the kind of piece-grabbing move novices play instantly but stronger players pause to calculate.|
White survives Black's counter attack with a winning advantage after 21. Nxa8 g3 22. Rfc1 Qh4 23. Qb6! Bf6 (23... Qxh2+ 24. Kf1 h4 25. Qg1 ) when play might continue 24. Nb5 Bd7 25. Nac7 Bd8 26. Qa7 b6 27. Qxb6 Qxh2+ 28. Kf1 h4 29. Ke1 h3 30. Nxd6 Nxc7 31. Nf5 Bxf5 32. exf5 Rf6 33. Qb3 (+5.01 @ 21 depth, Deep Fritz 14).
P.S.: Vaguely remembered this one, as it was a puzzle nine years ago. I knew the first move in the Sunday puzzle was 39...Rg3!!, but it took a while to recall 40. Bxg3 Nf5! .
|Aug-30-15|| ||Nick46: <jith1207: ...thanks to <CGdotCom> > here here, give us this day our daily puzzle. Even for those of us who are beyond learning but just want to have a bit of FUN.|
|Aug-30-15|| ||jith1207: <Nick46>: Ha Ha!|
|Aug-30-15|| ||wooden nickel: I had unsuccesfully tried both 39.Rg3 and 39.Nf5 separately... who'd think the solution was mixing them both together!
<patzer2: White survives Black's counter attack with a winning advantage after 21. Nxa8 g3 22. Rfc1 Qh4 23. Qb6!> Thanks for pointing that out, wouldn't even 22. h3 do the trick?
At any rate this is a case of <A threat is stronger than its execution. -Tarrasch>|
|Aug-30-15|| ||morfishine: <jith1207> The idea with repetitive training [ie: working multiple puzzles every day] is to improve one's pattern recognition. Time is saved when one learns to recognize patterns quicker, time which can then be used for calculating more variations and deeper. Hopefully, one will also increase their basic calculating speed, which in turn saves more time, etc. Patterns and time|
|Aug-30-15|| ||patzer2: <wooden nickel> After 21. Nxa8 g3 <22. h3 to unclear> (instead of 22. Rfc1 ), White's attack appears to weaken from a clear win to an unclear advantage. |
Deep Fritz 14 gives 21. Nxa8 g3 22. h3 Qh4 23.Bd1 Bxh3 24.gxh3 Qxh3 25.Rb2 Nh4 26.Re1 g2! 27. = (0.00 @ 23 depth).
There might be improvements for White there, but White's winning chances are much better after 21. Nxa8 g3 22. Rfc1 Qh4 23. Qb6! .
|Aug-30-15|| ||jith1207: <morfishine>: Absolutely True, indeed! I can see it so in myself.|
|Aug-30-15|| ||jith1207: <morfishine>: I see you have kibitzed 9,998 times. |
Don't be surprised and think it as a spam if <CG> shows in your screen that you are getting a reward for kibitzing 10,000th time!

|Aug-30-15|| ||reticulate: Once again, it's not the move (39...Rg3) but rather the clinching move after the move (40...Nf5) that I failed to see, as also happened to me on Saturday's puzzle. Today, I was trying to figure out whether Black would have to give up the Queen and try for a pawn-knight-bishop mate, and so missed the simple little Knight move that seals the deal. Sigh.|
|Aug-30-15|| ||farshids: Why 21 N to C8 and not A8?|
|Aug-31-15|| ||patzer2: <farshids> I think you mean why not 22. Nxa8 instead of 22. Nxc8. |
White probably avoided 22. Nxa8 because he feared the complications of the strong Black counter attack after 22. Nxa8 g3, where Black's Bishop on c8 is more useful than the Rook on a8.
Deep Fritz 14 gives 23. Qb6 Nxg2 24. Kxg2 Qh4 25. Qg1 Bh3+ 26. Kh1 g2+ 27. Qxg2 Bxg2+ 28. Kxg2 Nf6 29. Bxd6 Ng4! (+0.38 @ 22 depth) with a slight White advantage in a very difficult position.
Earlier 21. Nxa8 , with precise follow-up, gives White a clear winning advantage. See post above for analysis.
|Aug-31-15|| ||agb2002: Black has a bishop and a knight for the bishop pair.|
The position of the white king suggests 39... Rg3, threatening 40... Nxf3+ followed by 41... Qh4#. However, after 40.Bxg3 fxg3+ 41.Kxg3 Nf5+ 42.Kf2 (else 42... Qh4#) 42... Ng3 (42... Qh4+ 43.g3 Nxg3 44.Rxg3 Qh2+ 45.Rg2 Bh4+ 46.Ke3 Qf4+ 47.Kd3 + -) 43.Qc2 Qh4 44.Ke3 I'm unable to continue the attack.
Another option is 39... Nf5, changing the order of moves in the above line:
A) 40.exf5 Rg3
A.1) 41.Bxg3 fxg3+ and 42... Qh4#.
A.2) 41.Rf1 Qh4+ 42.Kg1 Ng5
A.2.a) 43.Bb4(c3,d2) Nh3+ 44.Kh1 Nf2+ 45.Kg1 Rxg2+ 46.Kxg2 Qg3#.
A.2.b) 43.Bxg3 fxg3 and mate in two.
B) 40.Bd7 Bxb6 41.Bxf5 Bxg1+ 42.Kxg1 Nf6 and Black seems to have some advantage [R+N vs 2B].
|Aug-31-15|| ||agb2002: I missed 41.Rh1, after 39... Nf5 40.exf5 Rg3, which wins for White.|
A most instructive puzzle.
