  GrahamClayton: "A bad day at the office for Senor Cantero" - Joe Gallagher "Winning With the King's Gambit".
Jan-18-17  Patriot: I decided on 18.Nd5, thinking 18...Qd8 19.Bxd6 (threatening 20.Nc7+, winning the queen) 19...cxd5 20.exd5+ Ne5 21.Bxe5 (threatening 22.Bxh8 and 22.Bc7+)

18...Qe6?? 19.Nc7+

18...cxd5 19.exd5 Ne5 20.Bxe5 dxe5 21.Rxe5

I'm not sure what happens after 18.Nd5 Qd8 19.Bxd6 Rc8. We seem to have won a pawn but the position looks much stronger than that.

Jan-18-17  coolknight: The black king is in the center and the white rook is lined up on the black Q-K, so is there a good way to get the e4 pawn out of the way?

18. Nd5 attacking the Queen and threatening forking the K and R from c7

If 18... cxd5 19. exd5 exposing the Re1 attack on Q and K and the only way to save the queen is to give back the knight 19...Ne5, and now white is way better with the black king in the center and continued danger to the queen

Jan-18-17  Patriot: Perhaps 20.Qf4 on my last statement? That puts all kinds of pressure on c7.
Jan-18-17  lost in space: I saw the following line:

18. Nd5 Qd8
(not 18...cxd5 19. exd5 and the queen is gone)

19. Bxd6 Rc8 20. Qf4 h6 21. Nc7+ Rxc7 (the reason for 19...Rc8) 22. Bxc7 Qg5 (the reason for 20. h6) 23. Qxg5 hxg5 24. Rh1 and the Ba5 will fall in addition without allowing any counterplay. White has decisive advantage.

Jan-18-17  coolknight: Hmm missed the 18...Qd8 line but 18. Nd5 still wins
Jan-18-17  Patriot: <lost in space> 20...h6 is an interesting move--what does it do? Black is tied down pretty good so he may not have much else. I'm glad you saw 20.Qf4 as well.

20...Ngf6 21.Be7 Nxd5 22.exd5 Qxe7 23.Rxe7+ Kxe7 doesn't look so good to me. I still like 21.Nc7+ there also.

Jan-18-17  ChessHigherCat: <goforit: The keymove is #14 Bxb5> That's a good point. The puzzle was kind of easy for a Wednesday but 14. white to move would be a good Friday puzzle at least. By the way, I have difficulty believing that your rating is only 1200 if you can spot things like that.

  OhioChessFan: Is it too prosaic just to push the e Pawn after 18...Qd8 and 19..Rc8? It's 2 AM and I'm satisified I'd win after 18. Nd5 regardless of the Black response. Maybe I'll look at this again after I wake up.
Jan-18-17  patzer2: A few days before a recent scholastic tournament in Fort Worth, Texas this month, my seven-year-old Grandson and I were studying the over-worked piece theme in a book of tactics for Juniors.

After a while, my grandson got to where he could spot the overworked piece and exploit it in a few seconds on most of the problems.

The practice apparently helped me on this puzzle as I immediately saw the Black Queen could not defend both the threat of 19. Bxd6 and 19. Nc7+ after today's Wednesday solution 18. Nd5 (+7.61 @ 23 depth, Deep Fritz 15).

P.S.: Much more due to his own self-study on sites like and than to my assistance, my seven-year-old grandson has steadily increased his chess skill and winning results.

Today he found his hard work and dedication paid off as he was informed by the USCF he had made the rating list for the top-100 juniors in the USA ages seven and under.

Jan-18-17  patzer2: Black's game goes south after 10...Bxf4? 11. Bxf4 (+0.60 @ 31 depth, Stockfish 7).

Instead, 10...Nd7 11. Be3 Qe7 (-0.68 @ 39 depth, Stockfish 8) holds it together for the second player. Also worth a try is 10...Qe7 11. Be3 Nf6 (-0.74 @ 29 depth, Komodo 10).

Jan-18-17  groog: Seems quite easy for a Wednesday.
Jan-18-17  YouRang: Wednesday 18.?

White would like nothing more than to get rid of his e-pawn, resulting in a queen-winning pin from Re1. There are a couple ways to do it. One way is to push 18.e5, and black (wanting to keep white's e-pawn on the e-file) replies 18...d5, and then it's not so clear how to proceed.

More forcing is <18.Nd5>, attacking the queen, and it can't be captured (18...cxd5? 19.exd5 pin & win Q).

The queen has to retreat, likely <18...Qd8> to remove the pin and prevent Nc7+.

click for larger view

<19.Bxd6!> and the N is still immune (19...cxd5 20.exd5 Ne7 21.Rxe7+ wins), while supporting Nc7+.

Jan-18-17  saturn2: Nd5.
If black accepts the sacrifice white`s rook on e1 becomes strong (<lost in space>even if the black queen can be saved by interposing the night on e5.) If black refutes there is Bxd6 or Nc7 to come.
Jan-18-17  AlicesKnight: I saw the points <YouRang> outlined - enough for a "won game". As mentioned a few days ago, 'not busted'.

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

The position of Black's king and queen suggest e5 and Nd5.

In the case of 18.e5:

A) 18... d5 19.e6 fxe6 (19... Ndf6 20.exf7+ wins) 20.Bf5

A.1) 20... Nf8 21.Bxg4 and White will win at least a pawn with an overwhelming position.

A.2) 20... exf5 21.Rxe7+ Nxe7 22.Qe3 looks winning. For example, 22... Kf8 (22... Ba6 23.Bg5 + -) 23.Bd6 Re8 24.Re1 f2 25.Bxe7+ Kf7 26.Qe6+ Kg7 27.Rf1 wins.

B) 18... dxe5 19.Bxe5 wins decisive material.

C) 18... Kf8 19.exd5 wins a pawn and looks horrible for Black.


In the case of 18.Nd5:

A) 18... cxd5 19.exd5 wins decisive material.

B) 18... Qd8 19.Bxd6

B.1) 19... cxd5 20.exd5+ Ne5 21.Rxe5+ Kd7 22.Bc5 with two extra pawns and a won position.

B.2) 19... Rc8 20.Qf4 cxd5 (due to Bc7) 21.exd5+ Ne5 22.Qxe5+ Kd7 23.Bf5#.


I think I'd play 18.Nd5.

Premium Chessgames Member
  whiteshark: <18.Nd5!> and that's it.

Alternatively to 18... Qd8, if <18...Qf8> (offering the Xchange) <19.Nc7+ Ke7 20.e5!> and white breaks through either with Bg5+ or exd6

Jan-18-17  morfishine: <18.Nd5> and Black's position soon falls apart


Jan-18-17  saturn2: This game is a lesson in how to get back in development:

1. Move pieces more than once and exchange them afterwards. 2. Make many pawn moves.

Jan-18-17  gofer: I got this one quite quickly, but feel a little bit let down by the immediate resignation.

<18 Nd5 ...>

<OhioChessFan: Is it too prosaic just to push the e Pawn after 18...Qd8 ?>

That was exactly my thought too. Nd5 doesn't just do everything that everyone else has already mentioned. It also does something far more interesting. It halts Pd6 where it is. So now we can play e5 threatening exd6+ without any possibility of black playing d5...

<18 ... Qd8>
<19 e5 dxe5>
<20 Bxe5 ...>

click for larger view

White threatens Bd6+, so the knight is still immune.

29 ... cxd5
30 Bd6+ Ne7 (Ne5 22 Rxe5 Kd7 23 Qf4 )
31 Rxe7+ Qxe7
32 Bxe7

<20 ... Nxe5>
<21 Rxe5+ ...>

21 ... Kd7
22 Bf5+ Kd6
23 Qf4

<21 ... Kf8>

Hmmm, okay, perhaps this isn't as productive as I had hoped... looks okay, but not as clean as the simple <19 Bxd6> winning another pawn (as the knight is still immune)...

Jan-18-17  Moszkowski012273: Actually 14.d5... was quite a bit stronger. As was playing it a few moves later.

  PawnSac: < OhioChessFan: It's 2 AM and I'm satisified I'd win after 18. Nd5 regardless of the Black response. Maybe I'll look at this again after I wake up. >

not necessary. black resigned! lol

yea it took all of about 3 seconds to see Nd5, but I guess it didn't qualify as a Monday puzzle because there was no queen sac. <grin>

  kevin86: Double attack! White chases the queen, then forks king and rook to win!
Jan-18-17  ColeTrane: 'tis true...even after precise play white is up three pawns and a queen to a knight....
