 | | al wazir: I went with 14. Nxe6. If now 14...Qc8, then 15. Nxg7+ Kd8 16. Re8+ Kc7 17. Rxc8+ Kxc8, and white has ♕ vs. ♖+♙+♙. If 14. Rxe6+, black can play 14...Be7, avoiding immediate mate. After 15. Rxe7+ Qxe7 16. fxe7, white has ♕+♗ vs. ♖+♙. Not a whole lot of difference. |
|
| Mar-27-18 | | ChessHigherCat: Sort of a variant on fool's mate with 14. Rxe6 Be7 (...fxe6 15. Qh5+ g6 16. Qxg6#) 15. Rxe7+ Kf8 (or queen sac) and it looks like it's still possible to exploit the f7 weak spot with 16. Ne6+ fxe6 (Kg8? Rxg7#) 17. Qh5+ and mate in 2. |
|
| Mar-27-18 | | stst: check if pure eye-balling misses something:
14.Rxe6+.......
(A)............fxR
15.Qh5+ g6
16.Qxg6#
(B).............Be7 (tougher defense)
15.fxg7 Rg8
16.Qh5#
if in (♗)
15.f7+ ♔x♙
16.♕h5 g6
17.♕xg6 let go ♔f8... still some lapses to go.. |
|
| Mar-27-18 | | stst: NN takes the easier route, but it's for White!! (to win more easily!!) |
|
| Mar-27-18 | | saturn2: 14 Rxe6+ and black cannot retake |
|
| Mar-27-18 | | stst: <...We're kind of like Pavlov's dogs. :-) Welcome back ... not Volvo, but Rang!!> Indeed that's some reason supporting NOT TO choose Nxe6... as it RANG!! Mon/Tue take the direct charge... Q/R-sac!! got it!! |
|
| Mar-27-18 | | ChessHigherCat: Correction: 17. Qh5 (not check), threatening Qf7# so black is forced to sac the queen. Has anyone found a forced mate in this line? |
|
| Mar-27-18 | | Cheapo by the Dozen: Now that feels like a Monday puzzle to me!
Oh, it's Tuesday already?? |
|
| Mar-27-18 | | agb2002: White has a bishop and a knight for the bishop pair. Black threatens Nxf6.
The black king cannot move and the white queen can go to h5 at once. Hence, 14.Rxe6+ Be7 (14... fxe6 15.Qh5+ g6 16.Qxg6#) 15.Rxe7+ wins more than a piece and a pawn: 15... Kf8 16.Qh5 g6 17.Qxg6 Qxe7 (17... fxg6 18.Ne6+ Kg8 19.Rg7#) 18.fxe7+, etc. |
|
| Mar-27-18 | | Honey Blend: If 14. ... ♗e7 15. ♖xe7 ♔f8, White has the lovely finish 16. ♘e6+! fxe6 17. ♕xd6:

It's Monday. Don't be fooled... |
|
| Mar-27-18 | | leRevenant: Much less fuss than yesterday's bleep on the radar. |
|
| Mar-27-18 | | goodevans: I can't see much to choose between 14.Rxe6+ and 14.Nxe6. Both are crushing. If you need to be able to find a clear distinction between them to solve this "Tuesday" puzzle then I've failed. |
|
| Mar-27-18 | | morfishine: <14.Rxe6+> |
|
| Mar-27-18 | | Mayankk: It probably is more difficult to go wrong in this puzzle. I mean what else can you play! And even the choice of sac hardly matters it seems. |
|
| Mar-27-18 | | malt: 14.R:e6+ Be7
(14...fe6 15.Qh5+ g6 16.Q:g6# )
15.R:e7+ Kf8 16.fg7+ or 16.Ne6+ wins |
|
| Mar-27-18 | | zb2cr: I went with 14. Rxe6+, Be7; 15. Rxe7+, Kf8; 16. Ne6+, fxe6; 17. Qh5, Qxe7; 18. fxe7+, Kxe7 and White has Q vs. R. |
|
| Mar-27-18 | | patzer2: I had difficulty deciding between 14. Nxe6 +- and 14. Rxe6+ +- for my solution to today's Tuesday (14. ?) puzzle. According to our Stockfish 9 tool's analysis of move 14.? both moves win easily with 14. Rxe6+ being the stronger choice. P.S.: Black's clealy decisive mistake was 11...h6?, allowing 12. e5! +- (+3.19 @ 21 ply, Stockfish 9). Instead, 11...Qb8 12. b3 ± (+0.82 @ 18 ply, Stockfish 9) gives Black a fighting chance. Earlier, Stockfish 9 prefers 9...Qd7 10. Nxc6 Qxc6 ⩲ (+0.47 @ 20 ply) over the game continuation. |
|
| Mar-27-18 | | patzer2: <BlueMooner: It seems to me that 4...b6 was the start of Black's woes...Is 4...b6 a normal variation in the English?> According to our Opening Explorer, 4...b6 is one of the least played opening variations (last played in 2016) in this English opening line, but surprisngly it has scored almost as well for Black as the popular choices 4...g6 and 4...d5. The computer prefers opening up a big hole on d5 with 4...e5, but most masters avoid it. |
|
| Mar-27-18 | | SpamIAm: <patzer2>- Agreed re 11...h6? being the decisive mistake. But 9...Ne5?? perhaps deserves not just one but two question marks as it moves an already developed piece again while other pieces are screaming to be moved and practically begs Kramnik to play 10.f4, gaining tempi by chasing it and reinforcing the upcoming 12.e5. NN probably didn't realize that the 'threat' to the c-pawn was phony (because of white playing Qa4+ in response) until he took his hand off of the horse. But even if white had to pause for 10.b3 he was going to play 11.f4 next with gain of time. Instructive. |
|
| Mar-27-18 | | SpamIAm: Seeing what happened even 13...Bh3!? was a better try. Still doesn't save the game but the move does have a certain Dada Defense look to it. |
|
| Mar-27-18 | | mjmorri: With 9...Ne5, NN decides to play for the win against a GM. After playing for about 500 years, you would think he would know better by now. |
|
| Mar-27-18 | | SpamIAm: <mjmorri>- LOL. When such a player instead opts for 9...Qd7 we will then attempt to find out his birth name. ;) |
|
| Mar-27-18 | | PJs Studio: I chose Nxe6 after ten seconds. Oddly enough, I may have seen Rxe6 over the board because as GM Lasker said “When you see a good move, don’t make it! Look for a better one.” I live by that motto in middlegames. (I’m fully aware Lasker was pre-GM. But he was WAY ahead of his time. So I use the title anyway...) 😝 |
