|May-11-17|| ||peristilo: I found the game's line in my head but I stopped before Rxg6. |
20. Rc6 Qd8 21. Qh6 Qf6 22. Rf6
|May-11-17|| ||SuperPatzer77: 20. Rc6! is much stronger than 20. Bc6 because White Rook on c6 attacks the Black Queen. 20. Rc6 is very forcible. |
|May-11-17|| ||Walter Glattke: White's Reply for 8.-Nxc4 is only 9.0-0,
but one can play even 8.-Ng4 9.0-0 Bc5
10.e3, and then 10.-Nxc4 - and what is White's replay to Nxc4 then?? Widjaja70: very good question, I think!

Here white's final move related to the solution of today's puzzle...
Navara vs A Dergatschova-Daus, 2007
|May-11-17|| ||Iwer Sonsch: Completely missed it. I somehow only looked at deflecting the queen, but not at blocking her.|
What I like about this game is that Black did not lose because of sudden, reasonless blunders, but rather he was slowly outplayed with a long combination as he accepted several minor sacrifices. 16...Nxe5(?) cost Black the game.
|May-11-17|| ||SuperPatzer77: <Peter Nemenyi: In the final position, if Black plays the relatively better 27...f5 rather than making luft for his king, the mate is 28. Bd5+ Rf7 29. Qg6+ Kh1 30. Bxf7 Bd3 31. Qh6+ Bh7 32. Bg6 Kg8 33. Qxh7+ Kf8 34. Qxf7#.>
You overlooked the Black f-pawn on f5. The Black Bishop cannot move to h7 because the Black f-pawn is already on f5.|
27...f5, 28. Bd5+ Rf7, 29. Qg6+ Kh8, 30. Bxf7 Bd3, 31. Qh6#.
Take a look at the final diagram (< Peter Nemenyi> you overlooked the Black f-pawn on f5 so the Black Bishop cannot move to h7 if he is on d3)

|May-11-17|| ||Oxspawn: <stacase> Please don't say <Way too easy for a Thursday>. It's Thursday and I got it!|
|May-11-17|| ||Iwer Sonsch: <20.Bc6> forces 20...Qd8 21.Bxd8 Rxd8 as well, winning by 4.69 (depth 23; Stockfish 7) rather than 8.54 (depth 31 after 22.Rxf6).|
|May-11-17|| ||Kent Swearingen: At least twice 20...Ne7 has been suggested as a refutation of 20.Bc6, but after 20.Bc6 Ne7 simply 21.Qg5+ Ng6 22.Qh6 any 23.Qg7#|
|May-11-17|| ||Walter Glattke: Yes, I also saw, that 16.-e5 was to play, and, you all will see, 16.-Ne5
still leads to mete, Iwer saw, that the end was coming already with the 16th move of black.|
|May-11-17|| ||OhioChessFan: <Oxspawn: Please don't say <Way too easy for a Thursday>. It's Thursday and I got it!>|
I agree with this. I know I've done it in the past, but I realize I should stop. We have players of all levels here, and it certainly doesn't help them to solve a puzzle any particular day of the week, feel good about it, and read a bunch of kibitzing saying how easy it was for that particular day of the week.
|May-11-17|| ||Strelets: <OhioChessFan> I couldn't agree more. The correct solution(s) would be quite difficult to find If you aren't familiar with deflection as a tactical device or theme. This is true of all of us at some point in our respective chess careers. Several earlier posters mentioned that they were able to recognize the hook of today's puzzle from solving yesterday's. That's awesome. That's how you become stronger in chess, by learning how to apply what you've seen in one situation to another.|
|May-11-17|| ||patzer2: The solution for today's Thursday puzzle, or even for a Friday or Saturday puzzle, could have been the decisive surprise move <17. Nf6+! gxf6>
If 17... Kh8, then White wins after 18. Qh5 h6 19. Bxh6 g6|
(19... Ng4 20. Bg5+ Nh6 21. Bxh6 g6 22. Qh4 Qa5 23. Bg5+ Kg7 24. Qh6#;
19... gxf6 20. Bxf8+ Kg8 21. Qh6 Nf3+ 22. Bxf3 d3 23. Qg7#)
20. Qh4 Nf3+ 21. Bxf3 Qa5 22. Bg5+ Kg7 23. Qh6#.
<18. Bxf6 Ng6>
If 18... Qb5, White wins after 19. Qh5 Qd3 20. Qxe5 Qf5 21. Qxd4 (+5.69 @ 36 depth, Stockfish 8) or 21. Rc5! (+5.63 @ 35 depth, Stockfish 8).
<19. Qh5> (+5.51 @ 33 depth, Stockfish 8
|May-11-17|| ||swclark25: I knew I had to block the Queen, so I also went with 20)Bc6 but I didn't consider 20)...Qd8. I wondered why White Bishop didn't take Black Queen immediately with 21)Bxd8, but then I noted that White Queen wanted to beat Black pawn to h6. |
Appreciate the kibitzing! I have plenty to learn on Tues, Thurs, any days!
|May-11-17|| ||ChessHigherCat: : <BOSTER: < ChessHigherCat : in fact it doesn't matter Rc6 or Bc6>. The big difference. Bc6 even doesn't attack black queen.
After 20. Bc6 Ne7>
I said at the end that 20. Rc6 was more forcing but 20. Bc6 wins, too...Ne7 21. Bxe7 and what? If Qc7 or bxc6 then 22. Bf6 and how does white stop mate?
|May-11-17|| ||stacase: <Oxspawn: Please don't say "Way too easy for a Thursday". It's Thursday and I got it!>|
Sorry, I thought 20 Rc6 was obvious. Sometimes you see it and sometimes you don't. This was one of those sometimes.
|May-11-17|| ||Kent Swearingen: <ChessHigherCat> and <BOSTER> note: After 20.Bc6 Ne7 White has mate in three beginning with Qg5+ as I posted above. I don't know whether 20.Bc6 is as good as 20.Rb6, but 20...Ne7 is certainly not a refutation.|
|May-11-17|| ||ChessHigherCat: < Kent Swearingen: At least twice 20...Ne7 has been suggested as a refutation of 20.Bc6, but after 20.Bc6 Ne7 simply 21.Qg5+ Ng6 22.Qh6 any 23.Qg7#>
Good point! The moral of the story is: if it at first you don't succeed, try angulation.|
|May-11-17|| ||swclark25: Would 22)...Be6 help Black's cause? Seems better than 22)...Be4|
|May-11-17|| ||swclark25: Sorry, meant to say seems better than 22)...Bg4|
|May-11-17|| ||JimNorCal: GM Howell is a chess player I'm not familiar with.|
Yet he's 3rd highest rated in England after Adams and Short. He's way above top 100 in the world, too. Maybe top 60 or so?
|May-11-17|| ||Cheapo by the Dozen: This is one of those mid-week puzzles that looks super-easy, making me wonder what I was overlooking.|
In this case, I didn't bother counting material at the puzzle's start. So I didn't notice that winning Black's queen was insufficient for a clear win, and that White hence had to still press the attack home afterwards.
Still, as for many such puzzles, it's fair to say that most of us would have played the correct moves to start the combination, and then dealt with further complications as they arose..
|May-11-17|| ||protonchess: @ whiteshark: that's a composed problem theme! Nowotny theme. Quite rare to find it in a played game in such pure form.|
On the other hand today's puzzle is just a straight interference. Even that is rare enough.
|May-12-17|| ||morfishine: <20.Rc6> is not "more" forcing, in fact, that statement misses the point entirely. We are not "forcing" the Black Queen to move: we are blocking the piece via an interference tactic.
Therefore, it doesn't matter which move White makes: <20.Bc6> or <20.Rc6> also works|

It seems like you're going way out of your way to "disagree" with my post while repeating all my ideas. I clearly said that 1) I recognized the interference tactic right away and 2) <PB> was right to say it was important to interpose "a piece" without specifying which one, and 3) that it didn't really matter because white wins either way. The "more forcing" part is just throwing a bone to <Boster> and <SuperPatzer77> who made a big deal out of Rc6 attacking the queen.|
