Kibitzer's Corner
Jun-18-19  zb2cr: Okay, straightforward. 27. Rxf7. This threatens mate next move with the double check, so Black has no alternative to 27. ... Rxf7; 28. Qg6. Now if 28. ... Kd7; 29. Qxf7, Qf8; 30. Nxf6+, Kd8; 31. Qxf8+, Bxf8. White has won 2 Pawns.
Jun-18-19  zb2cr: Huh. First to post, and I'm not right according to the game score. What's wrong with my line?
Jun-18-19  ASchultz: <zb2cr> I thought of Rxf7 and Qg8+ first, and liked it, because it had a forcing check. The two pawns will win quickly, but the loss of material is ruinous after Bxf7. Black doesn't just lose an exchange, as the e7-bishop is utterly undefendable. It takes a bit of time to check off there's no defense, but it's worth it.
Jun-18-19  Cheapo by the Dozen: Another fun one.

The big challenge in a mating combination is to cover d7. Accomplishing that with the knight is surprisingly difficult, so we should try to do it with the bishop instead. And indeed, after 27 Bxf7+, the threat of 28 Be6+ is sufficiently awful that Black has to forestall it with 27 ... Rxf7.

From there it's easy to check that while the more obvious checks and captures don't do as much for White, 28 Qg6 is a crushing continuation.

  agb2002: White has a bishop and a knight for the bishop pair.

White has Rxf7 and Bxf7+.

In the case of 27.Bxf7+ Rxf7 (27... Kd7 28.Be6+ Ke8 29.Qg6+ Rf7 30.Qxf7#) 28.Qg6 wins decisive material.

The alternative 28.Rxf7 Kxf7 (28... Bf8 29.Qg6 Qa5 30.Re7+ Kd8 31.Qe8#) 29.Qg6+ Kf8 30.Rd3 Qa5 (30... Qe8 31.Qxh6+ Kf7 -31... Kg8 32.Rg3+ and mate in two- 32.Qh7+ Kf8 33.Rg3 Qf7 34.Qh8+ Qg8 35.Qxg8#) 31.b4 Qa7 32.Rg3 Qg1+ 33.Kg2 Qd4+ looks unnecessarily complex.


In the case of 27.Rxf7 Rxf7 28.Qg8+ Kd7 (28... Bf8 29.Qxf7#) 29.Qxf7:

A) 29... Rc5 30.Qe6+ Kc6 31.Nxe7+ wins decisive material.

B) 29... Qf8 30.Nxf6+ Kd8 31.Qxf8+ Bxf8 32.Nd5 + - [N+2P vs b].


I'd play 27.Bxf7+.

Jun-18-19  patzer2: I suppose today's Tuesday puzzle is considered "simple" because almost any reasonable try wins.

My attempt was 27. Rxf7 +- (+11.79 @ 27 ply, Stockfish 10). It doesn't win as quickly as the game continuation with 27. Bxf7+ for mate-in-ten. However, it's still a sure win. So I'll take it.

These are not the only winning continuations, as Stockfish 10 indicates there are at least 25 winning moves. The biggest problem seems to be finding a 27th move that doesn't win for White.

P.S.: So where does Black go wrong?

Black's game takes a turn for the worse with 12...e5? 13. Nb3 ± to +- (+ 2.37 @ 32 ply, Stockfish 10).

Instead, 12...h6 (-0.05 @ 28 ply, Stockfish 10) holds it level.

Jun-18-19  abuzic: 27.Bxf7+ Rxf7 28.Qg6;
One move earlier, 26.Bxf7+ leads to the same position after 26...Rxf7 27.Qh5
Jun-18-19  Honey Blend: 27. ♖xf7 ♖xf7 28. ♕g8+ ♔d7 29. ♕xf7 ♕f8 30. ♘xf6+ ♔d8 31. ♕xf8+ ♗xf8 32. ♘h7 ♗e7 33. f6 wins at least a piece.

In a blitz game, this is what I might prefer.

Jun-18-19  malt: Went for 27.B:f7+ R:f7
(27...Kd7 28.Be6+ Ke8 29.Qg6+ )

28.Qg6 Kd7 29.Q:f7 Rc5
(29...Ba6 30.Qe6+ Ke8 31.Rg8# )

30.Qe6+ Kc6 31.N:e7+ Kb6 32.N:c8+

Jun-18-19  mel gibson: I saw the first move but not all the rest.

Stockfish 10 says mate in 10.

27. Bxf7+

(27. Bxf7+ (♗h5xf7+ ♖f8xf7 ♕g3-g6 ♔e8-d7 ♕g6xf7 ♖c6xc2 ♘d5xe7 ♗c8-a6 ♘e7-d5+ ♔d7-c8 ♕f7-a7 ♖c2-b2+ ♔b1xb2 a4-a3+ ♔b2-c2 ♕d8-e7 ♘d5xe7+ ♔c8-d8 ♖g7-g8+) +M10/47 14)

Jun-18-19  saturn2: I saw 27. Rxf7 Rxf7 28. Qg8+ Kd7 29. Qxf7 Qf8 (or Rc3) 30. Nxf6+

2 pawns plus was enough for me

Jun-18-19  saturn2: For my taste black did not treat well the opening. In the Scheveningen he should have played e5 and Be6 (alternatively Bb7) to control d5.
Jun-18-19  patzer2: <saturn2> Instead of the seldom played 8...Nc6 ⩲, one possible opening improvement is 8...Nbd7 = (the second most popular choice and the computer pick according to our Opening Explorer).

An interesting and instructive example of recent play with 8...Nbd7 is Black's win in I Agrest vs M Vachier-Lagrave, 2018.

Jun-18-19  thegoodanarchist: The Grasser's always greener on the other side.
Jun-18-19  lost in space: Got that quickly
Jun-18-19  lakshashishu: After 14 gxf6, it looks terrible for black. It's certainly not an opening for patzers:).
Jun-18-19  saturn2: <patzer2> As I have understood from this kind of Sicilians black should exchange his white bishop for the knight on d5. Otherwise like in our game after move 15 white's knight on d5 is overhelming.

Black can avoid this by having its white squared bishop on

1. e6 after black moves e5 and Be6
2. b7 in our way after Nd7, a6, b6 Bb7
3. c6 after Nc6, Bd7, NxNd4 Bc6

Jun-18-19  Momentum Man: Singh got the opening he wanted, a Sicilian. My opponents always play anti Sicilians like the Alapin.

Anyway, Black got what he wanted but wasn’t ready

Jun-18-19  JohnBoy: Like about 30% of the posts above, I went for 27.Rf7. The fact that Bf7 is stronger illustrates a fundamental weakness from my playing days. I'd see a decent move and cling to it, rather than respecting Lasker's maxim and looking for better.
