Jul-12-10  Brandon plays: I used to think that these types of problems were difficult to see. The difficult thing to see is a continuation that goes through multiple lines that is not forced. Qg2+ Rxg2 Nh3#
Jul-12-10  mworld: <once> a very informative post.

  kevin86: Here is what happens when two Cavaliers play together. We have yet to see what happens when three "Heat" play together.
Jul-12-10  jimmycook: I know this is outside the puzzle as presented but instead of 20...d4, could white have survived with 20...Rg2? Might have been interesting...

  chrisowen: Black burn down the house started 17..Nh5. Nine 9.Ng6 red balloons nights together then party again king gone without luft 21..Nh3#. The racing corvette it boom ailing white who's dunnroaming after Qg2+.
Jul-12-10  YouRang: Not quite as obvious as most Monday puzzles, and I didn't see it until the 2nd time I looked at 20...Qg2+. The first time it didn't "click" that the knight at h3, besides giving check, also seals off f2.

Indeed, this is a very pretty and efficient mate with knights, following a beautiful clearance sac with the queen, which (1) vacates h3 for the knight, and (2) forces white's own rook to do the job of blocking the king's escape to g2.

Jul-12-10  WhenHarryMetSally: queen sacrifice! gottit!
Jul-12-10  amaurobius: I spent perhaps a couple of minutes without getting it, so then I thought I'd check the possible queen sacs, which is of course cheating rather than solving it properly.

Wrt Blackburne's annotation at white's twentieth, I guess this ranks my level at slightly below beginner.

Jul-12-10  ZUGZWANG67: 20...Qg2+ and 21...Nh3 mate. As most of us, I guess, I already have this one in my inventory.
Jul-12-10  ZUGZWANG67: I've been reviewing and studying mating patterns for some weeks so this one was easy to me.

Once one understands that the Ns together cover all d2, d1, e1, f1, g1 and g2, all that remains is getting the appropriate W pieces on e2 and f2. And it doesn't matter wether the K stands on e1 or f1.

Or course, there is some variants:

I think that by spending time on mating paterns where a Q plays the central role, we tend to neglect those minor piece mate patterns. Yet quite often the Q merely becomes the luring piece that makes patterns such the aboves possible.

  patzer2: Today is Monday, and 20...Qg2+! makes a sham sacrifice of the Queen for mate-in-two.
Jul-12-10  Nullifidian: 20... ♕g2+ 21. ♖xg2 ♘h3#

I remembered seeing this at once. It's such a famous position.

Jul-12-10  lost in space: 20...Qg2+ 21. Rxg2 (foreced) Nh3#

Took me longer than usual on Monday.

Jul-12-10  caissafan1963: Has anyone ever seen a game that NN won?
Premium Chessgames Member
  Phony Benoni: Quite a few! NN has been winning games for 320 years!

It took him a while to get started, though, as he had a 293-year losing streak before his first victory.

Jul-12-10  MaxxLange: NN could have tried 14...Be3, even after missing the refutation of Black's absurd sacrifice. He'd end up with two Bish for Rook and Pawn, provided that he can hold his King
Jul-12-10  wals: With a LSB for two pawns White stumbled, 18.Rf2 -1.00.

Analysis by Rybka 3 1-cpu: suggests-

1. (0.40): 18.Qf2 Qh3 19.Rg1[] b5 20.a3 Kh8 21.d4 f6 22.Rg4 Rfd8 23.Rdg1 g5 24.d5 Ra6 25.Ba2 Ng7

2. (0.40): 18.Rg1 Qh3 19.Qf2 b5 20.a3 Kh8 21.d4 f6 22.Rg4 Rfd8 23.Rdg1 g5 24.d5 Ra6 25.Ba2 Ng7

3. (0.40): 18.Qe1 Qh3 19.Rg1[] b5 20.a3 g6

White fell on its sword, 20.d4 -#2.

Rybka suggests -

20.Rg2, -1.00.

Jul-12-10  EyesofBlue: Got it, but not without too long of a thought process. And it is only Monday?!
Jul-12-10  achieve: Took me somewhere between 30 secs and one minute, I guess.

First reaction after not immediately seeing the pattern was, "hmmm, is this a "Monday"? - and then had to check where to sac the queen for a Knight-Knight-mate (NN mate ;))

Nh3 *should* be a sitter, but still quite beautiful, this one.

Jul-12-10  beginner64: Almost didn't get it, and then solved it only by knowing it was a Monday puzzle.

I really don't have any reasonable expectation of being able to find this kind of combination OTB.

Jul-12-10  zooter: A little late to the party, but 20...Qg2+ 21.Rxg2 (only move) Nh3#

an amazing mate!

Jul-12-10  achieve: As <ZUGZWANG67> points out:

<I think that by spending time on mating paterns where a Q plays the central role, we tend to neglect those minor piece mate patterns.> Quite true! - that's why I have made a habit of underpromoting to light pieces when playing out to a mate against my chess engine, which reminded me of this study assignment I set out to solve - and UNDERSTAND; get used to harmonizing Knights and closing in on the lone king taking away more and more space:

Black to play and win (Should be possible in about 20 moves once you get the idea, maybe even less than 20)

Of course practising the B+N mate is textbook practise in this regard...

Keep practising! Towards mastery! ;)

Feb-03-13  Cemoblanca: "During a simultaneous exhibition at Cambridge University, the students thought they would gain an advantage by placing two bottles of whisky near the boards. Blackburne won all his games very quickly and finished off both bottles of whisky before the exhibition was over."


Feb-03-13  IndigoViolet: Blackburne's nickname in the chess world was 'Black Death', but his friends knew him as 'Hollow Legs'.

  Messiah: What a massacre! Excellently played by Blackburne, beautiful mate.
