Apr-07-17  protonchess: Contemptus Bishopus - admittedly a subtler case than most, because White seems to have some activity at first; but not for long.

  An Englishman: Good Evening: A French Defense where Black's light squared Bishop is the strongest minor piece on the board? Pretty good indicator that something went very wrong for White.
Sep-11-18  Cheapo by the Dozen: And this seems like a real Tuesday puzzle!

Bobby Fischer Teaches Chess is, once again, an appropriate reference. White's weaknesses are a back-rank mate threat and a loose-ish knight, and 28 ... Rd2 attacks both of them. 29 Nf6+ doesn't happen to solve anything for White.

  Penguincw: Moment of silence for the day today.

...

Wow. Interesting Tuesday puzzle.

The line I went for was 28...Rcd2. If 29.Nf6+ Kf7 30.Rf1 fxg2 and black crashes through on g3. (else knight is hanging)

But I did miss 29.Nc5. Grabbing on f2 results in a perpetual at best for black. Else 30.Nd3 saves the day just in time.

  patzer2: White's weak back rank gives Black a neat double attack with 28...Rd2! -+ (-6.15 @ 33 ply, Stockfish 9), when the first player has nothing better than dropping a piece with 29. Re1 29...Rxd7 -+ or resigning as in the game.

For an early White improvement, instead of 11. b3?! a6 ⩱ (-0.59 @ 31 ply, Stockfish 9), 11. Bb5+ Bd7 12. Bxd7+ = keeps it level.

Sep-11-18  saturn2: 28..Rd2 and neither
29 Rd4 nor 29 Nf6+ save white from losing a piece.
Sep-11-18  WorstPlayerEver: Remembered the names, but not the puzzle.
Sep-11-18  FSR: <Penguincw> You mean 28...Rcc2.
Sep-11-18  WorstPlayerEver: <FSR>

No, he meant 28... Rbc2. Now White can play 29. Nc5

Sep-11-18  Mayankk: I kept wondering what’s wrong with the prosaic Rcc2 and so missed the brilliant Rd2 trick.

As they say - even if you see a good-looking move, always seek something better.

  agb2002: Black has a bishop for a knight.

White is about to play Nc5.

The white king runs the risk of a back rank mate and the alignment of the knight and one rook on the d-file suggest 28... Rd2:

A) 29.Rxd2 Rc1+ 30.Rd1 Rxc1#.

B) 29.Nf6+ Kf7 wins the knight.

C) 29.Rd4 Rxd4 wins a rook and the knight.

D) 29.Re1 Rxd7 - + [b].

  johnlspouge: The White Rd1 is overburdened, defending the back rank mate on the rank and the Nd7 on the file. It therefore may not move, but

28...Rd2

ensures that it must.

  Penguincw: <FSR>, <WorstPlayerEver>

I meant 28...Rcc2, doubling on the 2nd rank.

Sep-11-18  RKnight: How many of you actually saw 28...Rd2 right away? I sure didn't. Couldn't solve it. Came back to it later, it's "easy" so I was too embarrassed to give up. Then finally saw it.

I call this a fine puzzle, obvious only in retrospect.

Sep-11-18  WorstPlayerEver: <Penguincw>

Ah, my confusion, I did not read your last line too well. Thanks for explaining.

I agree. The French Defense used to be my main response to 1.e4 and I once (as Black) got a passed e-pawn and won the game. Another pretty good indication that something went very wrong for White.

  Bubo bubo: The Rd1 must not leave the back rank, hence Black can fork that rook and the knight with 28...Rd2, winning a piece (29.Nf6+ Kf7).

  beatgiant: <cormier> <stockfish ... 5. Ngf3 cxd4 6. Bc4 Qd8>

By the way, Stockfish 9 prefers 3. exd5 (+0.18) over 3. Nd2 (+0.06) at 33 ply. Can that be where White first started to let the game slip? (Sorry, couldn't resist the temptation....)

  perfidious: Maybe 3.Nd2 is the beginning of the end, though Capablanca did not fare so well with Stockfish's preference in the first game of his title bout with Alekhine--perhaps both lose by force, despite the evaluation of the silicon monster.
