  patzer2: <awfulhangover> Black was busted whether he played 17...Nxf4 or not. So, rather than suffer a slow but sure loss or resign, I think it was just his way of conceding Unzicker a quick victory.

  Richard Taylor: <awfulhangover> how could he do this? by human error -but Sarapu was sometimes prone to "awful hangovers" (awfulhangover) (I think he had the odd beer on occasion -but was mostly fairly sober)- actually by the looks of this game - I know he had woman friend in Germany- maybe he was celebrating and so on with her the night before!! But it was all very proper I am sure...just too many drinks and some conviviality ..then he chose this crazy opening..

  patzer2: After 17. Bf4! all Black alternatives to 17...Nxf4 lose. For example, also losing for Black (per Fritz 8) is

A) 17... Qd4+ 18. Qxd4 Nxd4 19. Bxf7+ Kh8 20. c4 Be6 21. Kd2 Rd7 22. Be5 Rad8 23. c5 Bxf7 24. Nxf7+ Rxf7 25. Rxf7 Nf3+ 26. Kc3 Nxe5 27. Rxb7 a5 28. Re1 ;

(B) 17... Qxb2 18. Be5 Qb6 (18...
Rxd6 19. Qxd6 Qb6 20. Qxb6 axb6 21. Rb1 Ra5 22. Re1 Bd7 23. Rxb6 ) 19. Rxf7 ;

(C) 17... h6 18. Be5 a6 19. Ke2 f6 20. Bg3 Qxb2 21. Kf2 Qb6+ 22. Kf3 Qb4 23. Rae1 Qc3+ 24. Qd3 Qxd3+ 25. cxd3 ;

(D) 17... Kf8 18. Kc1 Kg8 19. Be5 Qe3+ 20. Kb1 f6 21. Bf4 Qb6 22. Nxc8 Raxc8 23. Qxe6+ Kh8 24. Qxb6 ;

(E)} 17... Rf8 18. Be5 a5 19. Kc1 a4 20. Qf3 f6 21. Qh3 Re8 22. Nxe8 a3 (22... Kh8 23. Nxf6 gxf6 24. Rxf6 ; 22... Kf8 23. Nxf6 gxf6 24. Bxf6 Ra6 25. Qxh7 ) 23. Nxf6+ gxf6 24. Bxf6 axb2+ 25. Bxb2 ;

and (F)} 17... Bd7 18. Qf5 Rf8 19. Be5 Qd8 20. Nxf7 Qe7 21. Bd6 Qxf7 22. Bxf8 Qxf5 23. Rxf5 Rxf8 24. Rxf8+ Kxf8 25. Kd2 .

  patzer2: <Richard Taylor> Rather than speculate about Black's physical or mental condition, I'd prefer to think he just overlooked the possibility 17. Bf4! when he played 15...Bxd6?? Then after 17. Bf4!, I suggest he conceded White a quick mate in an otherwise lost position.

  patzer2: <Euripides> Thanks for the reference to the game Short vs Minic, 1985, where Black plays the defense 15...Rd8! I'll run Levy's suggested analysis improvement for White in this line on Fritz 8 and post my comment at that game.
Jul-18-05  zb2cr: I love Monday puzzles. Got it in seconds, like most Monday puzzles. Monday, I feel like an intelligent chess player.

By Friday, my ability to get most puzzles under simulated game conditions is about 50% and I'm feeling stupid.

  patzer2: <euripides> Referring to the analysis posted at the Short vs Minic, 1985 game, it appears that with strong play, White can scratch out an endgame win after 15...Rd8! 16. Bd3! However, the analysis is long and complex, and Black may still have reasonable drawing chances against less than perfect play (e.g. human error). Thanks again for the reference to Levy's analysis.
Jul-18-05  xxdsdxx: Quick smothered mate for a Monday.
Jul-18-05  alexandrovm: Queen sac, mate with knight
Jul-18-05  YouRang: Like everyone else, I got this fast. Nice easy Monday puzzle.

  kevin86: I thought i had this one easily-then i looked in shock that my mating knight was pinned. The pinning piece was diverted by the queen sac---and the knight mates as planned. A typical Monday puzzle-with a little pixieish touch.

  Doctor Who: Finding 17.Bf4! was the real brilliancy here.
Jul-18-05  alphee: I've not been there for a while but this one was easy.

Premium Chessgames Member
  patzer2: After a suggested improvement by <azaris> at the Short vs Minic, 1985 game cited above, it looks like 15...Rd8! might be good for the draw afterall.
Jul-18-05  yoozum: I love Monday puzzles!
Jul-18-05  Kelvieto: Hasn't this aren't been one of the daily puzzles?

  Richard Taylor: <Benzol> No good - its a conspiracy I tell you ! I worked for Telecom's predecesors - the good old new Zealand Post Office -but my guess is you had cable fault and they had to rejoint - probably- a 300 or 400 pair cable -or even rplace a cable section - sometime they get hit by lihgtening which puts holes in the cable sheath - which lets water in ) - we've had some really bad weather lately - did you hear that brilliant thunder storm!!

re the game - I found a great game of Roger Court versus Sarapu butso far havent found any 'brilliancies' by Ortvin (he was more a "strategical" player I think - I and Glen Turner went to see Roger when he was living in Ellerslie (in a flat) - he had asthma and died that year I think or the next year 1967 -one of our best talents...very nice fellow too

  Richard Taylor: <Patzer 2> I was joking - Sarapu didnt overlook much although I drew with him once - the position -looking at it from Black's side now --doesn't look so bad for Black - as you say 17 Bf4 seems to win

What about 15. ... Bd7 ?

Jul-19-05
Premium Chessgames Member
  patzer2: <What about 15. ... Bd7 ?> Fritz 8 gives 15... Bd7 16. Nxc5 Nxc5 17. Be3 Bg4+ 18. Kc1 Nb3+ 19. axb3 Qxe3+ 20. Kb1 Be6 21. Qxb7 Bxc4 22. bxc4 Rad8 23. Qd5 Qe2 24. Rf3 Rd7 25. c5 (+2.56 @ 14/52 depth & 1271kN/s).

BTW, congratulations on your draw with Sarapu. He was a strong master and that's quite an accomplishment.

  OlimpBase: who says a king in the middle of the board is the handicap?

  Richard Taylor: <patzer2> yes that line looks fairly convincing but 18...Rc8 might be better...

I was at my "peak" when I played (about 1982 I think it was)(I got a draw - in fact I should have won) game but I was never in Ortvin's league - despite this game and my draw - as you say - he was very stong player - And he was great personality - very much liked in NZ -he had great sense of humour also. They say if he had stayed in Europe he would have been a GM or close to it...

  FSR: Not to be immodest, but I actually was the first to make the chess world generally aware of 18.Nxd6! (which I learned of from Levy's book) when I published my game Rhine-Sprenkle, USA 1982 in Chess Informant Volume 32. My game continued 15...Rd8 16.Bd3 Bxd6 17.Qh5 f5 18.Nxd6! Qxd6 19.Qxf5 Qxh2 (Minic later innovated with 19...Nf8 against Short) 20.Qf7+ Kh8 21.Bg5! Rg8 22.Be3 Nd8 23.Qf2 (23.Qf4! is better) Nc6! 24.Kd2 Qd6? (24...Ne5! and if 25.Rh1 Nxd3! comes close to equalizing) 25.Rh1 h6 26.Bc5! Qd5 (26...Qc7 27.Qf6!! ) 27.Qf4! Rd8 28.Rxh6+! Kg8 (forced) 29.Rh8+! Kxh8 30.Qh4+ Kg8 31.Qh7+ Kf7 32.Qg6+ Kg8 33.Qh7+ Kf7 34.Rf1+ Bf5 35.Rxf5+ Qxf5 36.Qxf5+ Kg8 37.Kc1 1-0. In Informant 33, 18.Nxd6! was voted the 8th-9th most important theoretical novelty in Informant 32. (Larsen ranked it first, and Byrne ranked it second I believe.) The game was also cited in ECO and MCO, and occupies a whole chapter in all three editions of Nunn's "Beating the Sicilan" book.
Oct-01-06  Uzi: My Fifteen Minutes of Chess Fame would make for an interesting book. Who was that guy who hit Kasparov over the head with a chess board?
