Jun-27-18  mel gibson: Gee wizz - I didn't see that Black gains a free Knight and a file for its Rook.
Jun-27-18  An Engliishman: Good morning: <ChessHigherCat> I believe this December will be 12 years.
Jun-27-18  WorstPlayerEver: Take my knight away
Jun-27-18  Marmot PFL: Q sac and g6, not too difficult but still very cool.

  Breunor: I'm with NBZ. I found this right away; but if somebody doesn't tell me 'Black to play and win' I know I wouldn't have seen this in a real game.
Jun-27-18  BOSTER: PUSH 15.f3 opening the diagonal for black bishop was a mistake. But if you wanted to move f2 pawn, was better to move to f4.
Jun-27-18  Marmot PFL: <I'm with NBZ. I found this right away; but if somebody doesn't tell me 'Black to play and win' I know I wouldn't have seen this in a real game.>

In a real game I'm sure you would find it after playing 15...Re6, but white missed the point of that move, otherwise I think he would have played 16 f4 which gets his Q and Rf1 into the game.

Jun-27-18  CHESSTTCAMPS: Material is "even" but black's bishop is much stronger than the white knight in this situation, controlling dark squares in white's weakened castled position. Black only needs to expose the white king along the file:

18... Qxg3! 19.hxg3 (f4 Qxd3 leaves white a piece down; alternatively b4 ab can only delay the same consequences for one additional move) g5 20.Qxd6 Rxd6 21.Rf2 Bxf2 and 22... Rxh6# follows - a corridor mate, nice or nasty depending on your perspective.

Jun-27-18  Patriot: Seeing the immobile white king, it was then just a matter of opening the h-file and seeing if a rook was in position. So, <18...Qxg3 19.hxg3 g5> and mate is unstoppable.

I like problems like this much more than the "insane" problems because these are much more logical to me. Many of the insane problems are logical but the combinations are usually based on elements more subtle. Since I can't calculate like a machine I'm not worried about positions that follow no logic where combinations cannot be deduced much less sensed.

Jun-27-18  lost in space: Got it quickly
Jun-27-18  DrGridlock: Interesting how everything fits together on this one. I got the idea of Qxg3 followed by advancing black's g-pawn to set up the rook check on the h-file. Looking for different defenses for white, I thought that Qd2 might have been the saving resource. The queen gives white coverage on f2, allowing the rook to potentially block the bishop on the diagonal, and covers h6, stopping black's rook.

Took me a while to figure out that after g5, black's pawn would be blocking white's queen on the diagonal!

Aug-17-18  LivBlockade: <For those still confused as to why this is a Saturday puzzle,> please be aware that: < co-founder and longtime webmaster Daniel Freeman died on July 24, 2018, at the age of 50.>

See for more information.

Since then, the daily puzzle has been on a sort of autopilot, repeating puzzles. Today's puzzle for August 18 (note - I wrote this yesterday!) was from Wednesday June 27 2018, or 7 weeks and 3 days ago. Because of the shift, the day of the week associated with the puzzle has shifted for now.

One way to look at it is:
Thursday is the new Monday.
Friday is the new Tuesday.
Saturday is the new Wednesday, etc.

The stars and level of difficulty displayed reflect the puzzle that <would> have normally been shown, so they are now off also.

I hope this helps clear up the confusion that a few people seem to comment on each day.

Aug-18-18  dumbgai: Relatively best for White is 19. f4 but being a piece down he is still clearly lost.
Aug-18-18  DarthStapler: Surprisingly easy.
Aug-18-18  Huddsblue: A Wednesday puzzle.

  al wazir: 18. h4 Qf6/Qd8 (18...Qf4? 19. g3; 18...Qh5? 19. g4) 19. Nh6+ Kg7 20. Ng4 Qxh4+ 21. Nh2 g5 22. Qe2 Rh6 23. g4 Be3 24. Qg2 Bf4 25. Rf2 Bxh2 26. Qxh2 Qxf2 0:1.

  OrangeTulip: Great puzzle!
Aug-18-18  sfm: So funny. After 16.Ng3,Qg5 White sees the threat of QxN, and plays 17.Nf5. After -,g6 the rooks way to h6 is blocked, and the knight can return to g4. Not so!

Before 15.f3 there was nothing wrong with White's position, but he found the perfect suicide.

After 16.Ng3?,Qg5 it is getting a bit difficult, though there was still time for 17.Ne2 with a defendable position.

Aug-18-18  sfm: Should of course have been "the knight can return to g3", not g4
Aug-18-18  AlicesKnight: Familiar again (and not a 'Saturday' problem) - but still beautifully simple; ....Qxg3 and after hxg3, ...g5 opens the way for the R (missed it last time).

Analysis by Houdini 4: d 22 dpa

1. = / + (-0.32): 17.Qd2 Be3 18.Qe2 g6 19.Rd3 Bd4 20.c3 Bc5 21.Rfd1 Kg7 22.a4 Ra6 23.Nf1 Rb6 24.g3 Qd8 25.Kg2 Rb3 26.Ne3 Qb6 27.R1d2 Re8 28.Ng4 h5 29.Ne3

Aug-18-18  dumbgai: <cormier> Your starting position has the white rook misplaced.
Aug-19-18  CHESSTTCAMPS: Black's splendidly placed bishop controls the escape squares for white's vulnerable king. Opening up the h-file will expose white to an edge mate from black's lifted rook:

18.... Qxg3! 19.b4 (hg g5 20.Qe3 Bxe3 21.Rf2 Bxf2 and white can't stop 22...Rh6#) ab! (but not 19... g5?? 20.bc) and white can only avoid a quick checkmate by playing on a piece down.

Aug-19-18  CHESSTTCAMPS: I forgot that I posted a solution to this one in June.
Jan-01-21  Gaito: White missed a very strong and brilliant move. Instead of the blunder 18. Ng3??, he could have surprised Geller with the brilliant stroke 18.g4!!, see diagram:

The white knight is taboo, on account of 18...gxf5 19.gxf5 Rh6 20.Rg1 Bxg1 21.Rxg1 Rg6!? 22.Rxg5 Rxg5 and White has the better ending. Or else 18...a4 19.Ng3, and White has at least an equal position.
