Haven't been to the coffee house in a while. I'm surprised this has turned into an actual chess thread.
Hi Percy, The shortest mate that I'm aware of is: 1. f3. . .e5(or e6)2. g4. . .Qh4++ Black mates on the 2nd move. It has been a long while since I've messed with any chess puzzles but maybe someone will remember: Wasn't this known as the "Scholar's mate"? P.S. to DNAunion: Yes, I am aware that trading the rook for the knight in that position assures the stalemate. My point was that you had to have the opportunity for the double attack to begin with. Since Nf6 was obviously black's last move prior to your double attack on the knight & pawn with your rook, I would be interested to know what space this knight occupied prior to this move and if the move to f6 was a capturing move or just a move to a clear square. Those are the details that will make all the difference in the analysis. Namaste' Amlodhi

The fastest mate occurs in two moves (Black mates White on his second move). I won't post it since the mod decided to hide EC's solution. I believe it's called Fools Mate. The funny thing is (at least EC may find this funny), is that on an episode of Columbo a world champion killed his opponent the match was with and while giving a simultaneous, Columbo was questioning the player. He was so rattled that he fell into the Fools Mate! Sorry, but there's no way a world champion would ever non-intentionally fall prey to that mate.
There's also a quicky called Scholar's Mater, I believe. Here's a mate on move 3 I just made up. 1. c4 Nc62. e3 Nb4 3. Ne2 Nd3# Here's one from a "real line": one that has at least some chance of occurring in a real game. 1. f4 e52. fxe5 d6 3. exd6 Bxd6 4. Nf3 g5 5. h3 Bg3#

If you read the previous post to my blanked out solution I was told I could go ahead and post it.
Dope!

quote: Here's the position a move earlier. White:King on g2 Rook on g8 Pawns on h4 Black:King on e4 Bishop on d4 Knight on g4 Pawns on h6 What can Black do to win? Obviously, I am threatening the knight. 1. ... h52. Rg5 Nf6 3. Rg6 Nd5 (if 3. ... Ng4 then 4. Rg5 again) 4. Rg5 Nf4+ 5. Kh1 followed by 6. Rxh5 = 1. ... Kf5 (or Kf4)2. Rxg4 = So Black cannot protect the knight...he needs to move it. 1. ... Nf62. Rg6 = (which occurred in the game) 1. ... Ne52. Re8 = (intending 3. Rxe5) 1. ... Ne3+! ("box")2. Kh3 From this position, it's going to be hard for Black to win. He has to always avoid White's giving up his rook for the knight, which makes it hard for him to approach and win White's pawn...and Black's pawn is weak. It would be an interesting position to play out. **********************************Let me point out that this was a "blitzish" game. I remember the opening moves. 1. d4 d52. c4 dxc4 3. Nf3 Nf6 4. e3 b5 5. a4 c6 6. Nc3 b4 7. Na2 b3 8. Nc3 Ba6 9. Ne5 e6 10. Bxc4 Bxc4 11. Nxc4 c5 12. Qxb3 cxd4 13. Qb5+ Nbd7 14. exd4 Rb8 15. Qa6 Rc8 16. Bf4 Nb6 17. Nxb6 axb6 18. O-O Rc6 19. Rad1 Bd6 20. Qb5 Qd7 21. d5 Rxc3 22. Qxd7+ Nxd7 23. bxc3 Bxf4 24. Rfe1 Ke7 25. dxe6 fxe6 26. g3 Bd6 27. f4 e5 28. fxe5 Nxe5 I can't remember the next several moves. But withing a few moves we ended up at: White:King on f1 Rooks on a6, d1 Pawns on g3, h2 Black:King on e6 Rook on c3 Bishop on d6 Knight on d3 Pawns on g7, h7 My threat is 1. Rxd6+ Kxd6 2. Ke2. Black decided to trade down with. 1. ... Rc12. Rxc1 Nxc1 3. Kg2 And in a few more moves, we ended up in the orginal position I brought up. As we can see, several errors were made in the opening and middle game, but it was a blitz game, where I played the move that popped into my mind first, without analysis.

I feel left out.
Here's one I just thought about. Though I think I may have dug it up out of memory so it may not be original. (PS I am doing this in my head so apologies if an error - but I am sure I think - lol) White:pawns h2 b3 rooks b7 f1 knight e4 queen f2 king h1 Black:pawns a5 g5 d4 rooks e3 d8 bishops e7 e8 knight h6 queen h3 king g8 White to move and mate in 3. Have fun!!! It's actually pretty easy.

Hello DNAunion, etal,
Late tonight, but I believe I have found some interesting lines for the first game you illustrated and will post some tomorrow. Also, I had (at one time) gotten pretty well burnt-out on chess puzzles but your last one (with, perhaps, mate in 16) looks more interesting, so I think I will take a look at that one tomorrow as well. In the meantime, for those who enjoy interesting moves: Crushing move by Bobby Fischer in 1965 U.S. Championship tournament, for anyone who may enjoy finding it. White position: Kh1Qg6 Rg1 Be4 pawns on a2,b2,c3,f3,f5,g7,h4 Black position: Kg8Qc8 Rd8 Nh7 pawns on a6,b5,c4,f6,f4 White's (Fischer's) move. Amlodhi

Solution to problem 1: Force Black King to hem himself in between his rooks, then mate with Knight. Really neat puzzle!!!
I'll look at the other later. --Percy

Took me a couple of seconds because I started by looking at Qxh7+, which does nothing (well, it loses for White, but most winning combinations begin by "losing"). Once I rejected that I immediately saw 1. Qe8+ and wins.
1. Qe8+ Rxe82. Bd5+ Re6 3. Bxe6+ Qxe6 4. fxe6 That's as far as I needed to get mentally to see the win. The rest I worked on by physically moving pieces around the board. White threatens 5. e7 so ... 4. ... f55. e7 (other moves win as well) Nf6 6. Rg6 Ne8 7. h5 and White just marches his h-pawn up and wins. For example, 7. ... a5 (7. ... Nc7 8. Rc6!? Ne8 9. Rc8)8. h6 b4 9. h7+ Kxh7 10. g8(Q)# [This message has been edited by DNAunion, 04-02-2004]

You got it. The general principle is called Philidor's legacy, I believe.

Hello DNAunion, etal,
RE: Mate in 16. With White's crushing move, Black doesn't have a chance. Very impressive though, as it required perfect play on both sides, i.e. for White to retain the initiative, and for Black to hold out for 16 moves. White to move and mate White:King on h2 Queen on c4 Rooks on c8, f7 Bishop on c2 Knight on d6 Pawns on e4, g2, h4 Black:King on g6 Queen on a1 Rooks on a8, g4 Bishop on f6 Knights on e5, g8 Panws on g7, h5 The crushing move: Rxg7 Thus: Rxg7+....Bxg7 If black moves Kh6 then:Nf5++ If black moves Kxg7 then:Qxg8+........Kh6 Nf5++ Qf7+......Kh7 If black moves Kh6 then:Nf5+............Kh7 Qxg8+.........Kg6 Qxg7++ If black moves Nxf7 then:e5+.............Kh6 Nxf7++ Qxg8+....Kg6 If black moves Kh6 then:Nf5+............Kg6 Qxg7++ Qf7+.......Kh7 If black moves Nxf7 then:e5+.............Kh6 Nxf7++ If black moves Kh6 then:Nf5+............Kh7 Qxh5+.........Bh6 Qxh6++ Qxh5+.......Bh6Rc7+..........Rg7 Rxg7+........Kxg7 Nf5+...........Kg8 If black moves Kh7 or Kh8 then:Qxh6+........kg8 Qg7++ If black moves Kf8 then:Qxh6+........Ke8 Qe6+..........Kd8 Qe7+..........Kc8 Nd6+..........Kb8 Qb7++ Bb3+........Nf7Nxh6+......Kg7 If black moves Kf8 then Qxf7++If black moves Kh8 then: Nf5+...........Kg8 Qxf7+.........Kh8 Qh5++ Nf5+........Kf6 If black moves Kf6 then Qxf7++If black moves Kg8 then: Qxf7+..........Kh8 Qh5++ Qxf7+...........Ke5Qd5+...........
