Stockfish gives it a slight plus score +0.40 (22 ply) 28.Bxc6 Qxc6 29.Qd2 h6 30.Nd6 Re6

Jul-03-18  patzer2: I was immediately tempted by 28. Qxe5 Qd8 =, but then I remembered Emanuel Lasker's maxim "when you see a good move look for a better move."

That's when I saw the double attack 28. Qf3! +-, which threatens back rank mate or the win of a piece. So I picked it as my solution for today's Tuesday puzzle.

P.S.: Black's position was already bad after 25. Bxe4 ± to +-, but 25...c6? 26. dxc6 +- (+7.23 @ 23 ply, Stockfish 8) made it too easy for White.

Instead, 25...Qg4 26. Rfe1 ± to +- (+1.64 @ 34 ply, Stockfish 8) or 25...Bc8 26. d6 ± to +- (+2.01 @ 34 ply, Stockfish 8) offers more resistance.

For an earlier improvement, I'd start with the opening. After the popular moves 8...Bf6 and 8...f5, it seems difficult to avoid getting a bad Bishop -- especially against a super GM like Nakamura. To avoid this, I prefer 8...d5 which gives Black's minor pieces easier development and more active play.

According to our Opening Explorer, 8...d5 has been more successful than the popular moves 8...Bf6 and 8...f5. Moreover, 8...d5 = (+0.10 @ 36 ply, Stockfish 8) is the computer's first choice.

Some recent examples of play with 8...d5 are Black's win in Kiril D Georgiev vs A Korobov, 2017 and White's win in A Goganov vs I Frolov, 2018.

Jul-03-18  1.e4effort: My original thought was Qf3, but I guess I've been trained by CG over the years to look for sacs on Monday and Tuesday, so I thought its gotta be Qxe5 followed by RxQ followed by Rf8#. Shoulda went with my gut, I guess...
Jul-03-18  BOSTER: White to play 26. for puzzle is good too.
Black pos had two weaknesses: Bc6 and square f8.We has to find how to use this.

Jul-03-18  swclark25: I also bit for Qxe5. Thanks <patzer2> for reminder to look for better move.

Got a chuckle from <BxChess: Sonia lamba: ChrisOwen is inimmitable.>

How do you compare "time to khuch khuch khuch mating net..well hell done by Ne5 scroupting..Nothing so basty" with "vizin pound wound hound vints built tubby butty bunts bints huffs flush huhus cuffs chuff"

  Peligroso Patzer: <ChessHigherCat: 28. Qf3 is brilliant. 28. Qxe5 just loses a piece after 28...Bxe4>

<areknames: *** <28. Qxe5 just loses a piece after 28...Bxe4> No, White simply plays 29.Qxe4 and the Queen is untouchable. ***>

First, the only winning move is, as per Nakamura's text, 28. Qf3.

With regard to the above analysis of a possible <28. Qxe5>:

Although it is true that if Black replies 28. … Bex4?? (per <ChessHigherCat's suggestion (*)>, the reply 29. Qxe4 (per <areknames>) would avoid the loss of a piece and preserve a slight advantage for White, the superior <29. Nd6!> (forking e8 and e4) would win outright.

(*) - <Note>: Better choices for Black here would be either 28. … Qd8 or 28. … Bxb5, both leaving White with only a small advantage).

Premium Chessgames Member
  ChessHigherCat: <Peligroso Patzer> Bxe4 was my suggestion from nearly two years ago which I admitted was wrong. This time I gave the best line:

Qxe5 is just a draw according to SF:
1) =0.00 (26 ply) 28...Qd8 29.Qf4 g5 30.Qf6+ Qxf6 31.Rxf6 Bxe4 32.Rxb6 Ra8 33.Nd6 Bd3 34.Rb7 Rf8 35.Nf7+ Kg8 36.Nh6+ Kh8 37.Nf7+

Premium Chessgames Member
  Peligroso Patzer: My apologies, <ChessHigherCat>. I guess I did not read all of your comments here with sufficient care.

In the given position, due to Black's problems on the back rank, the idea of <28. Qxe5> was obvious, and after seeing that <28. ... Bxe4> would be refuted by <29. Nd6> (continuing, for example, with: 29. ... Rb8 30. Rf7 Qg4 31. Ne8! winning), I concluded that <28. Qxe5> was the solution.

Lasker's maxim (as quoted above by <patzer2>) should always be kept in mind.

Jul-03-18  CHESSTTCAMPS: Material is even, but black has a vulnerable back rank that white can exploit with 28.Qf3!, winning at least a minor piece:

A. 28... Bxe4 (or Bxb5 or N moves and others) 29.Qf8+ forces mate

B. 28... Qc8, Qe6 or Qe7 avoids the back-rank mate, but loses to 29.Bxc6.

Jul-03-18  landshark: I'm glad I didn't choose 28.Qxe5 even for a draw because the SF moves given by <Chess Higher Cat> are crazy. Much easier to just go Qf3. Bring on Wednesday!
Jul-03-18  gabriel25: The taste varies in sound effects poetry, now Chrisowen has let some words with sense in and it makes a nice contrast to repetitionist Sonia, I envy both their sense of disorder and C his typing, while S is terse belongs to belonging.

Todays problem first move I tried can't find an answer, belongs to a protomonday a day that came before the first week ever.

Premium Chessgames Member
  ChessHigherCat: <landshark> I went for Bf3, too. I just fell into the Qxe5 debate quagmire because I made a comment over a year ago about why Bf3 was better but I didn't criticize Qxe5 for the right reasons, and somebody caught me up on it (as they have every right to do). After all, "perfectionism makes perfect" or something like that.
Jul-03-18  gabriel25: Why did I find the problem so easy? Others seem not to think so. Its the eighth rank that is atractive. BxB has no business, the queen check is covered by the knight, so its his problem, he finds no answer loses a bishop. Faster thought than written. I type very slowly.

  ChessHigherCat: < gabriel25: Why did I find the problem so easy?>

My theory is that you did it because you are absolutely amazing! Can I please join your cult?

Jul-04-18  hdcc: I am coining a new term: alongside "Chess Blindness" we now also have "Puzzle Blindness". Whereas the former prevents us from seeing something that is there, the latter causes us to see something that is not there - to eschew the quiet move in favour of a flashy forcing one that invariably involves a sacrifice.

I may have found the answer if I hadn't been presented with the position as a puzzle, but, as it was, I became thoroughly fixated on Qxe5 - and very frustrated because it would not work :-(

Apropos the discussion re. Chris Owen: has he realised that his name is actually an anagram of "cohnerwis"?

Premium Chessgames Member
  ChessHigherCat: <hdcc: propos the discussion re. Chris Owen: has he realised that his name is actually an anagram of "cohnerwis"?>

Wow, that's almost as good as "When is orc?" or "Crone wish"!

Aug-24-18  stacase: 28.Qf3 That was easy (-: Black has to defend against the Queen sacrifice and while he does that take the Bishop.

OK it took a little more than a few seconds but not that much.

Aug-24-18  Jambow: Yeah grabbed that one in blitz mode after about 30 seconds as the back rank threats jump off the board. More like a Monday or Tuesday than a Thursday or Friday puzzle and I'm only running on 2hrs worth of sleep too.
Aug-24-18  CHESSTTCAMPS: Material is even, but the black king is vulnerable to a back rank threat. The wrong approach for white is the non-forcing, blundering 28.Qxe5?? Qc8! 29.Qf5 Bxe4 and black turns the tables.

Instead, white should find the double-threat move 28.Qf3! and now:

A. 28... Bxe4 29.Qf8+ Rxf8 30.Rxf8#

B. 28... Kg8, h6, g6, Qe7, Qe6 (and other checkmate-delaying moves) 29.Bxc6 and that's all she wrote.

Aug-24-18  CHESSTTCAMPS: In my preamble, I missed that 28.Qxe5? Qc8(??) is met by 29.Nd6 and that 28... Qd8 is the one feasible path to salvage a draw. Congrats to those who found this without engines.
