Mar-29-17  nalinw: I didn't see the solution at all ... but that is because I was distracted by

15. ... Bc3+

which looks lovely until one realizes that the White Queen also covers e3 ....

It is, but 12.Kc2 Bd1# in that game is even more amusing!

  Once: <yadasampati> I know what you mean. I used to rail against people saying "First!". Then I mellowed. Old age, I suppose, and the fact that the news headlines are bad enough without adding any more angst into the world.
Mar-29-17  takchess: Deja VU.I once played a game with the first 6-8 moves of the Opera game before it veered off. Now that was fun. I hope one day i hope to play a double rook sacrifice [without losing 8)] like the young lion euwe vs reti game.
Mar-29-17  takchess: Also nicely said Once.

  rodchuck: Yes, the text solution is very nice. I must confess the queen "sacrifice" never occurred to me (shows my level of chess, I'm afraid) - I would have played Bb8 with the threat of Re8. Not so pretty but still conclusive I think?

  PawnSac: < thegoodanarchist: Of course <Nightsurfer> is right about this being reminiscent of the classic Reti vs Tartakower, 1910, but I look at the final mating pattern and think of Morphy vs Duke Karl / Count Isouard, 1858 >

exactly what i was thinking. I've used that idea many times in games and have referred to it as the Morphy mate. Here's a game I played with a friend back in 1982

[REMOVE WHITE'S QUEEN] 1. e4 e5 2. Nf3 d6 3. d4 d5 4. exd5 Qxd5 5. Nc3 Qd7 6. dxe5 Bb4 7. Bd2 Nc6 8. O-O-O Qe7 9. Bb5 a6 10. Bg5 Qe6 11. Rd8#

of course he was a complete beginner. But i first learned the idea from that

Paul Morphy vs Duke Karl / Count Isouard
"A Night at the Opera" (game of the day Dec-02-07) Paris (1858) · Philidor Defense: General (C41) · 1-0

  Fusilli: <yadasampati: I do not understand why some commenters just repeat the solution from the game. It does not add anything.>

Technically true, but it's their way of participating. Presumably, they are sharing they got it right. I believe some post first, then look at the solution.

<Once> summarized it perfectly:

<It's all okay. It's a free world.>

Mar-29-17  stst: d1 is the weakest spot for White.
Rather than waiting the B(d7) release, why not have a give first, take/mate later by the Q: 15....... Qd1+
16.KxQ (forced) Bg4 dis&dbl+ (R&B, as planned)
17.Ke1 (restored, only escape sq.) but then Rd1# supported by B(g4)
Mar-29-17  BOSTER: < yadasampati: why some comments repeat the solution from the game>. You need the talent like <chrisowen> to write unique solution.
Mar-29-17  stst: <...Including this one.>

Yeah, when we glaze here, already proved that we got some leisure time. Reading others, we communicate, and, as said, it's free world.... we choose to, not obliged to. Have an open mind, and, Just enjoy kibitzing!!

  chrisowen: <yadasampati> It's all greek to me;
Mar-29-17  Macbeth: I went for 15....,Bb5 - double menace of Qd1 or Qe2 mate, forcing white to check in a8 and hand over the Queen. Of course this wins, but not so nicely as the game continuation
Mar-29-17  erismi: I like these kind of games because it provides a lot of opportunity to figure out where things went wrong.

IMHO 6. Qe2 was a poor choice. 6. d3 (defend c4, release bishop, defend knight, guard e4) would've been much better.

Things went sideways with 8. Qxc7. Much better to just trade off the queens. With no back-up and nothing else hanging the pawn grab doesn't make sense.

I suspect 9. Qxf7+ is a stronger reply to bishop d6. Two pawns for a knight is not great but it could be worse, white has the potential to build a strong pawn center. It also removes the Qxg2 threat. If one assumes no more blunders from either player the game is lost after Qxg2.

Mar-29-17  RandomVisitor: The moves 2 and 3 for this game seem to be reversed.

  ChessHigherCat: 23. Qd1+ is a good illustration of the "choose the most forcing move principle" (Bc3+ is less forcing because there are two possible reactions: Bd2 or bxc3, not counting the third option of overturning the board and calling for mommy)
Mar-29-17  morfishine: <PawnSac> Nice game PawnSac!

*****

Mar-29-17  Marmot PFL: The first guy is right. This game looks more like a 1910 game than one from 2010.
Mar-29-17  peristilo: people get annoyed for innocent 'first' comment???

  fredthebear: <Penguincw: Excellent Opera Mate on move 17.> Agreed, as the pawn on f2 prevents the mated king's escape.

Some might refer to this game M Amini vs R Gralla, 2010 as a "Morphy Mate", but most associate such a pattern with the rook occupying the open g-file as the bishop mates a castled king in the corner. See this diagram of Morphy's Mate: https://srteitsson.wixsite.com/rest...

The classic book "The Art of the Checkmate" by Georges Renaud and Victor Kahn (first published by Simon and Schuster, Inc. 1953) https://store.doverpublications.com... has twelve pages dedicated to "Morphy Mate" involving a queen sacrifice on any square it's needed. However, Paul Morphy's famous Opera House victory Morphy vs Duke Karl / Count Isouard, 1858 is not included in the Morphy Mate chapter w/queen sacrifices.

Thus, "Opera Mate" is a more refined modern term w/the supported rook next to the mated uncastled king. Paul Morphy had so many different mating finishes that it's better to use the final position of the Opera House victory to distinguish from other arrangements.

This decoy queen sacrifice on the back rank certainly does remind one of Reti vs Tartakower, 1910. Reti vs Tartakower, 1910 So it's also correct to call today's 17-mover a "Reti Mate". Reti's victory had two possible final moves, depending upon which way the mated king went. The unused move ...Ke8 would have resulted in an "Opera Mate" structure.

Some might even refer to such back rank mates as "Mayet's Mate", because the bishop supports the rook giving checkmate on the back rank. https://chessfox.com/mayets-mate/#:...

I refer to "Mayet's Mate" more specifically as a bishop on the open long diagonal supporting the rook in the corner giving mate. After watching Jozarov's video, I'm considering broadening my definition, still yet leery of what sources influenced him (misinformation leads to more misinformation, as we know from bogus social media posts): https://www.youtube.com/watch?v=kG2... Here's the famous Nimzowitsch game Nimzowitsch vs Alapin, 1914 that Jozarov references. Tracking down the accurate history of Mayet's Mate has been difficult.

Many sources leave out Mayet's Mate altogether. Here's an example of an excellent source of information, but no Mayet's Mate: https://chesstempo.com/tactical-mot...

One should note that Anderssen's Mate (checkmating rook in corner supported by pawn - see diagram: https://srteitsson.wixsite.com/rest...) and Mayet's Mate are often confused in chess literature, but let's leave it at that.

One can avoid the name debate and simply say M Amini vs R Gralla, 2010 is a "Discovered Double Check & Mate"
