  patzer2: The queen psuedo sacrifice 17. Qf6 illustrates the importance of looking at every check and capture, and following it through to the end of every forced variation.

While 20. g4+ leads to a very pretty three move mate, 20. Rh3+ also leads to a quick mate.

Aug-22-03   Shadout Mapes: I only saw the combination up to move 19, but it was already obviously sound due to the number of resources at white's disposal.
Aug-22-03   Larsker: In chess puzzles, always take the queen sac into account. There's one big book of chess puzzles at Amazon where the users complain that 80% of the solutions are in fact queen sacs!

  Honza Cervenka: I saw 20.Rh3+ Nh4 (20...Kg4 21.Ne3#) 21.Rxh4+ Kg6 22.Rh6#
Aug-22-03   ramdaz: Does moving pawn h3 + in 20th move help a quicker mate

  Honza Cervenka: <ramdaz> If 20.h3, then what about 20...Bxf4 or 20...Nxf4?

  ChessPraxis: <to Shadout Mapes> To think that a line is "obviously sound" may be good enough for a blitz game, but when you're sacrificing your Queen you'd better KNOW that you're going to come out on top in every continuation.

  patzer2: According to this site, shredder 7.04 may be a bit stronger than fritz 8: http://www.f27.parsimony.net/forum6...
Aug-22-03   rollerblader1324: shredder 7.04 is stronger...its #1 worldwide while fritz 8 is #3...but it doesnt make 2 much of a difference
Aug-22-03   Marnoff Mirlony: Shredder is not stronger than Fritz.

  patzer2: <Marnoff Mirlony> At the German web site above, a test of numerous games showed Shredder 7.04 beating Fritz 8 about 60% of the time. John Watson makes the following interesting commentary in one of his recent reviews at http://www.chesscenter.com/twic/jwa...

"I looked at the latest SSDF Computer Rating List that I could find online and discovered these figures: with the same amount of memory and processor, Shredder 7.04 is rated at 2810, Shredder 7 at 2770, Fritz 8 at 2762, Chess Tiger 15.0 at 2720, Junior 7.0 at 2697 (note that Junior 8.0 is out), and Hiarcs 8 at 'only' 2682. For the average player, I doubt that any of this makes much difference. Of the two engines that I use most, I think of Fritz as being tactically sharper and HiArcs as having some interesting assessments that strike me as 'positional'; but the difference isn't very significant. One can spend a lot of time playing around with (and against) these programs. I view them mainly as an assistant to my analysis."

Aug-23-03   Marnoff Mirlony: Fritz is a Champion. He would drop Shredder almost as fast as Fischer cleaned out Larsen and Taimanov.
Apr-25-05   Autoreparaturwerkbau: Mackenzie's 17.Qh6+ is just soooo cool!

  patzer2: Mackenzie's 17. Qh6+!! is a decoy which initiates a forced mate, using a second key decoy in 20. g4+! to complete the combination.

The move 17. Qh6+!! is listed as the solution to number 1184 in Chess Informant's 1980 "Encyclopedia of Chess Middle Games," where it is classified as a decoy (spelled "dicoying" in this multi-language reference).
