Oct-01-07  TheaN: I now notice that the victim here is The World's current opponent. Has been a long time though XD.
Oct-01-07  vlado23: I think 22.Nf7 is countered by 22.. Nf5 - black will loose the knight but gets to fight on
Oct-01-07  Waitaka: Missed this one. Instead of the sacrifice, I choosed Rf7.
Oct-01-07  ahmadov: I was very quick to find this one...
Oct-01-07  noctiferus: <aidfarh: Since this was correspondence> IMO, the basic question is: since this was correspondence, why 21...Qe5? Fairness, allowing the opponent to finish with a nice combination, since the game is anyway lost?

  gawain: Oh yes! I liked the geometry of this one.
Oct-01-07  newton296: the big question is would black play ...K x Q to see if it's really mate in 1 !

yep gert ! it is.

Oct-01-07  whiteshark: Monday Monday, so good to me,
Monday Monday, it was all I hoped it would be.

  patzer2: The decoy 22. Qh8+! solves today's puzzle with a mate-in-two.
Oct-01-07  PAWNTOEFOUR: i could lie and say i got this one...but i won't....i guess i was too focused on Rxf8+ for some reason
Oct-01-07  Crowaholic: <If he does, I'll have to sulk, since I wasted more time than that, contemplating how to make Rxf8+ work, before considering Qh8+.>

Same here. Took me about a minute (where I tried to sac Q or R on different squares, as well as discarding 22. Nf7 Qh5 as too complicated for a Monday) to realize how dumb I am: Qh8+!! My only consolation is that Timmerman missed it almost 30 years ago, in a correspondence game! Yes, kids, they didn't have Deep Fritz back then. ;-)

<beginner64: Note that 22. Nf7 is refuted by Qh5>

Incidentally, that still seems to be winning, e.g. 23. Be2 Qxh6 24. Nxh6+ Kh7 25. Rxf8 Kxh6 26. Rh8+ Kg5 27. e5 with the threat of Nc3-e4-d6 etc.

Spike 1.1 instead suggests 23. Qf4 and claims it to be even stronger, but I don't quite understand the threats yet.

Of course, neither line compares to the good old Q sac to mate next move as played in the game.

Oct-01-07  Rodrigo Gutierrez: Solved this one in less than a minute... gosh I feel I AM improving at this (maybe I'll actually get to solve a THURSDAY puzzle soon...)
Oct-01-07  YouRang: Nice Monday queen-sac deflection. :-)

Look for the piece that is guarded only by the king, and you'll often find a weak spot.

  kevin86: A very simple,but brilliant deflection by queen sacrifice! A perfect Monday puzzle.

  fm avari viraf: In any game, one has to Master the Tactics & Techniques to relish the finer aspects of the game & Chess is no exception. Here, the deflection theme well accomplished with the beautiful Queen sacrifice leading to mate!
Oct-01-07  zinos: É hope this week's theme is not "games GM Timmerman" lost...
Oct-01-07  amadeus: Real easy. Half star.
Oct-01-07  Eurotrash: Thank God its Monday.
Oct-01-07  znprdx: No comment - can I take my move back? :)
Oct-01-07  zb2cr: Took me longer than usual for a Monday, since I started by looking at 22. Rxf8+, Kxf8; 23. Qh8+, Ke7 etc. Then I noted the 22. Qh8+, with a dismissive thought: "Okay, then 23. Nf7+ wins the Queen back but leaves me a piece down." Then--the light dawned.
Oct-01-07  outsider: checkmate in correspondence?! wow. never thought it could happen
Oct-01-07  pawnofdoom: wow. Ive never seen a checkmate in correspondence before. And this guy who's black is supposed to be the "world champion" that is versing the whole world right now in correpondence :P
Oct-01-07  vibes43: It would be interesting if CG would throw one like this in on maybe a Thursday. We wouldn't be looking for a Q sac then. We (I, at least) would be following other lines much deeper unless/until I hit upon the solution. And when/if I saw the solution, I would triple retrace my steps to be sure. Of course there would be a lot of grumbling.
Sep-02-11  Bloemansdall: The black player was not Gert-Jan Timmerman but A.C. Timmerman.
