Aug-28-17 | | stst: Strange but interesting... one rook gone but the other enters to kill:
27.Nxe6 dis+ Bxc1 (forced)
28.Rc7#
No escape nor taking away this R possible, K locked, killed (mated, in chess parlor.) |

 | | perfidious: Surprising really to see Chigorin take up the cudgels for Black in the Compromised Defence, but stranger things have happened. |
|
Aug-28-17 | | offramp: It's also a bit surprising to see Chigorin with two bishops and his opponent with two knights. |
|
Aug-28-17 | | jith1207: <K locked, killed (mated, in chess parlor> All this time, I have been thinking that when a chess game ends, the Queen of the winning side takes the captured king to be her keep. For this reason, the legends say that the Queen likes contact mates, or even more smothered mates, than a non-contact mate. |
|
Aug-28-17 | | AlicesKnight: 27.Nxe6+ Bxc1; 28.Rc7# looks "it". Black self-block. |
|
Aug-28-17 | | saturn2: monday warm up with mate in 2. |
|
Aug-28-17 | | weary willy: Would that white's second knight had been at a4, with access to b6... |
|
Aug-28-17 | | Cheapo by the Dozen: Why not 17 ... Kc8? Breaking the pin on the d-pawn might have inhibited the e6 break. I don't think Nd6+ with the goal of back-rank mating at e8 would actually have worked in response. |
|
Aug-28-17 | | stacase: <Whitehat1963: Took me way longer than it should have!>
Me too. I finally realized that not only did 27.ne6+ force 27...Bxc1 but also covered d8 and supported the Rook for the 28 Rc7#. Pretty tricky for a Monday. On delete & repost for a typo:
Oops 27...xc1 wasn't forced. Black could have played 27...Bc6 but that leads to 28.c1xc6# |
|
Aug-28-17 | | stacase: Oh boy, Now I see that Black could stave off the mate until move 29 with 27...Bc5 but White's Rook just chews right down through the c column. Ugly all the way around for Black. |
|
Aug-28-17 | | leRevenant: Much harder than last Monday & much more satisfying. |
|
Aug-28-17 | | leRevenant: Simon Win, Mikhail Chagrin. |
|
Aug-28-17 | | morfishine: <27.Nxe6+> and no, White has not overlooked Black's DSB due to 27...Bxc1 <28.Rc7#> Very cute
***** |
|
Aug-28-17 | | malt: 27.N:e6+ B:c1
(27...Bc6 28.R:c6# / Rc7#)
28.Rc7# |
|
Aug-28-17 | | zb2cr: 27. Nxe6+ is a deadly discovered check. If 27. ... Bxc1; 28. Rc7#. Black could also try interposing one (or both!) of his Bishops, but then White just takes with the c-file Rook. |

 | | patzer2: For today's Monday puzzle solution 27. Nxe6+! initiates a quick mate-in-two. If 27...Bc5, then 28. Rc7#.
If 27...Bc6, then 28. Rc7# or 28. Rxc6#.
If 27...Bxc1, then 28. Rc7#.
Black's decisive error appears to be 23...a6? allowing 24. Nxc7! +- (+2.09 @ 29 depth, Stockfish 8.) Instead, 23...Rf8 ⩲ to = (+0.23 @ 35 depth, Stockfish 8) holds, as play might go 23...Rf8 24.Rc1 Kd8 25.Nxc7 Rxf2 26.Nxe6+ Ke8 27.Nc5 Rf7 28.Rg8+ Rf8 29.Rxf8+ Kxf8 30.Kf1 Bc8 31.Nb5 Kg8 32.h3 Bf5 33.Nd6 Bg6 34.g4 Bc7 35.Nce4 Bxd6 36.Nxd6 Rb6 37.Nc8 Ra6 38.Rc7 Rxa2 39.Rxa7 Rh2 40.Ra3 Kg7 41.Kg1 Rd2 42.Nb6 Kf6 43.Nc4 Rd3 44.Rxd3 Bxd3 45.Ne3 h6 46.Nd5+ Kg5 = (+0.08 @ 41 depth, Stockfish 8.) Earlier, Black can apparently improve and secure a slight advantage with 21...Ke8 ⩱ to = (-0.33 @ 34 depth, Stockfish 8) as
play might go 21...Ke8 22.Ncxa3 fxe6 23.Rxg7 Kf8 24.Rd7 Bc6 25.Rdd1 Rg8 26.g3 Rg6 27.Nc3 Rf6 28.Rf1 Ke7 29.Nc4 Rd8 30.Rc1 Rf5 31.Nxb6 axb6 32.Rfe1 Rd3 33.Ne4 Kd7 34.f4 Bd5 35.Re2 Rf8 36.Rce1 h6 37.Nf2 Ra3 38.Ng4 c5 39.Nxh6 Rxa2 40.Rxa2 Bxa2 ⩱ (-0.36 @ 30 depth, Stockfish 8.) P.S.: At first glance, it appears Black can put up more resistance with 24...Bxc7. However, after 24...Bxc7 25.Rc1 Bd5 26.Rcxc7+ Kd8 27.h4 Bxa2 28.Nc2 h5 29.Ne3 Bd5 30.Rgd7+ Ke8 31.Nxd5 exd5 32.Rxd5 Ra8 33.Re5+ Kf8 34.Ra5 Rh6 35.g3 Rh8 36.Rc6 Ke7 37.Rcxa6 Rxa6 38.Rxa6 Kf7 39.Kg2 +- (+3.47 @ 35 depth, Stockfish 8) White appears to have a won Rook and Pawn endgame. |

 | | thegoodanarchist: I think this is what's called an "Arabian Mate" They are always aesthetically pleasing. |
|
Aug-28-17 | | The Kings Domain: Nice and easy puzzle and a good mauling of the great Russian. |
|
Aug-28-17 | | Strelets: Several others have pointed out the Arabian mate that follows the cute 27.Nxe6+. I just want to say that memorizing checkmate patterns is a good use of study time. How often do you see an Arabian mate when the king isn't in the corner? Yet here it is, with Black's king hanging out on c8. |
|
Aug-28-17 | | Pedro Fernandez: c1_rook making its deadly job before die. |
|
Aug-28-17 | | SpamIAm: <Strelets>- I recommend the book "The Art of the Checkmate" by Renaud and Kahn. |
|
Aug-28-17 | | BOSTER: Maybe 12...0-0 should be try. |
|
Aug-28-17 | | Altairvega: Two formidable white rooks and an Arabian horse. the black bishops try to save the lost position but in vain.. |
|
Aug-28-17
 | | drollere: splendid 2N combination. the first move from the puzzle was obvious, but getting to that position from e6 was not. |
|

 | | kevin86: Arabian Mate in two! |
