I agree. This is a gem!
12.Nd5! is a nice move.
20.Rxa6! Not 20.dxc6? Bc5+!
22.Qxd6+! Very nice. |

| | fredthebear: <optimal play> No, that is not my intention. Here lately I have been working off the Home Page, Recent Kibitzing list of games. You kibitzed, which put the game(s) on the list that I was working from. To be more specific, I usually work off the BOTTOM of the list (before the games disappear) so as not to walk over someone's efforts before others have had a chance to read a more rigorous post like yours. My comment re-elevates your post, basically reviving it to the top of the list. So my useless comment actually puts your useful comment back into circulation at the top (when the formatting is working properly). This is a fantastic game and deserved more attention! Thank you for bringing this game to our attention <optimal play> and keep up the good work! |

| Sep-03-22 | | Brenin: White's R on a4 is en prise, and 20 dxc6 loses to Bc5+, so play 20 Rxa6, further exposing Black's K, threatening the B on c6, and if the B moves then 21 Rxd6 Qxd6 22 Bf4. |
|
| Sep-03-22 | | Brenin: After 21 ... Bb7 Black's goose is cooked by 22 Qxd6+, and 21 ... Ka7 loses to 22 Be3 with Qa1 to follow. Black's only hope of survival at this point is 21 ... Qb7 22 Rxb7+ Bxb7, with R+N for the Q, but then 23 Be3 or 23 Qd4 look crushing for White. |
|
| Sep-03-22 | | Refused: with 20.Rxc6? Qxc6! 21.dxc6 Bc5+! -+
not being an option.
20.Rxa6 would be my choice. After that white has a second pawn for his piece, the black king remains terminally weakened. White now really threatens to capture on c6, if the Bishop vacates c6 cheapos like 21.Rxd6 Qxd6 22.Bf4 are looming.
TBH I am not quite sure how to continue with black after 20.Rxa6 I see, black went with the old Mash theme song Suicide is Painless and opted for pretty checkmate. |

| Sep-03-22 | | jrredfield: I resisted the obvious 20. Rxa6 after favoring it at first since it seemed too easy for a Saturday. But I like others ruled out 20. Rxc6 and 20.dxc6, leaving Rxa6 the clear choice. Komodo Dragon (depth 40):

about the hanging Queen on d1. LOL

| Sep-03-22 | | agb2002: White has a pawn for a knight.
Black threatens Bxc6.
Any capture on c6 loses to ... Bc5+ (20.Rxc6 Qxc6 21.dxc6 Bc5+). The alignment of both black bishops on the sixth rank and the alignment of the black king and the dark square bishop on the b8-h2 diagonal suggest 20.Rxa6: A) 20... Bb7 21.Rxd6
A.1) 21... Qxd6 22.Bf4 wins decisive material.
A.2) 21... Qe7 22.Rxd8+ wins a second pawn and gets three connected passed pawns. B) 20... Bb5 21.Rxd6 as in A.
C) 20... Bxd5 21.Bxd5 Nxd5 22.Qxd5 wins decisive material (22... Bc5+ 23.Qxc5 Qd1+ 24.Kg2 Qxc1? 25.Qc7#). D) 20... Nxd5 21.Rcxc6 looks crushing. |

| Sep-03-22 | | goodevans: This is an absolutely terrific game. Can't believe it hasn't been GOTD. Going to spend the rest of the day trying to think of a suitable pun (avoiding the obvious references to doner kebabs). Inviting others to beat me to it! Looks like Black was already lost after the <12.Nd5!> sac. Donner chose to return the material immediately but Black fared no better with <13...Kd8> in Chiburdanidze vs H Hoffmann, 1989. Wondering if the N-sac was part of Dely's opening prep. If not, I wonder how much was calculation and how much was instinct. |

| Sep-03-22 | | TheaN: Hah, 6/6 so far this week! Been a while again. This one took me a while, and granted, I didn't choose the most optimal offense. I looked at it, but sadly discarded it after all complications. I'm talking about <20.Rxa6>, which ends up being the correct point to being the piece down. White is foremost threatening 21.Rcxc6 which is the best move after 21....Nxd5, and moving the bishop allows 21.Rxd6 with 22.Bf4. No single defense prevents both. The issue with taking on c6 is the discovered check on c5, which is prevented by Pd5 being in the way, pretty much. Having said that <20....Bxd5> muddies the waters a little bit. Here, I continued consistently with <21.Rxd6!?>. Not bad, White is winning after <21....Qxd6 22.Bf4 Qxf4! 23.gxf4 +-> but Black still ends up using the discovered attack and seems to win Bg2 back for the pieces after 23....Bxg2: this I missed. However, White can threaten enough with 24.Qe2, after 24....Rhe8 25.Qc4! +- threatening Qc7+ with Ra3# is enough to win the bishop anyway. Quite a bit better on move 21 is 21.Rb6+! as per game, although it's complex. The game line 21....Bb7 is forced mate after the destructive 22.Qxd6+! #6. 21....Ka7 has no merit either as it allows White to develop his only missing piece with tempo 22.Be3 +- #8, and the 'best' 21....Qb7 allows 22.Rxb7+ #19 as it's with check and White has time to defend against the discovered attack. I spotted the latter two solves, but not the answer to Bxb7. I'd say seeing the option of Rxa6-xd6 with Bf4 is key here, so I'll consider this a solve. On to Sunday for my first full week in years. |

| Sep-04-22 | | sfm: Donnerwetter!
Wow, one of the greatest games we have seen for some time.
Time and time again it seems like Black has made it OK.
One brilliant move after another, starting with 12.Nd5! shoot holes in that idea. |
