I didn't get the point today. |

| Nov-24-16 | | YuvalKenoll: I thought only just as 《An Englishman》
What have we overlooked today? |
|
| Nov-24-16 | | AlicesKnight: Saw 23.Ng4 but expected ....Rxe3 as a reply, at which I am unclear about how to win (too sleepy) - unless after 24.fxe3 the threats of Nf6+ and Be5 are unstoppable. <An Englishman> seems to have an interesting line. |

 | | agb2002: White has a bishop for a rook and a pawn.
White has 23.Nxg6 and 23.Ng4.
In the case of 23.Ng4:
A) 23... Rxe3 24.Nf6+ Kh8 25.fxe3
A.1) 25... dxc4 26.Be5
A.1.a) 26... cxd3 27.Ne8+ and 28.Qg7#.
A.1.b) 26... Bc6 27.Nd7+ f6 28.Bxf6+ Kg8 29.Qg7#. A.2) 25... Bc6 26.Be5 Re7 27.Nxh7+ f6 (27... Rxe5 28.Nf6+ Nh7 29.Qxh7#) 28.Bxf6+ Kg8 29.Bxe7 looks winning (29... Nxh7 30.Kh8 Qxh7#). B) 23... Qd8 (or Bc6) 24.Nf6+ Kh8 25.Rh3 Re1+ 26.Bf1 followed by Qxh7+ and mate. C) 23... Bc8 (to prevent Rh3) 24.Nf6+ Kh8 25.Qxf8#. -----
23.Nxg6 looks more complex but also winning. For example, 23... Rxe3 24.Nxf8 Rxd3 25.Nxh7 Rd1+ 26.Kg2 dxc4+ 27.Kg3 Rg1+ 28.Kh4 f5 29.Nf6+ Kf7 30.Qh7+ Kf8 31.Qg8+ Ke7 32.Qg7+ and 33.Qd7#. -----
I'd probably play 23.Ng4. |

After trying every way to make a sacrifice at g6 or f7 work (I'll spare the details), I finally decided to try the logical <23.Ng4>.
click for larger view
Logical, because:
- it threatens Nf6+ forcing Kh8, leaving the Nf8 precariously defending against Qxh7# (and that N can be attacked with Bd6) - it opens a discovered attack on black's unguarded rook on e7. - after Nf7+ Kh8, if black hasn't taken take our Re3, we have Rh3!, threatening the Arabian mate: Qxf8+! ...Qxf8 Rxh7#. Black can't survive all of these threats.
Happy Thanksgiving to those in the U.S. (others are still permitted to be thankful) :-) |

| Nov-24-16 | | mel gibson: DR4 64 Bit shows
23 Ng4 mate in 8.
It's not that easy to see 8 moves ahead! |
|
| Nov-24-16 | | gofer: White has given up a pawn and an exchange for this attack,
so he's not going to worry about giving up more material to
see it through, but what to give up next?! I would recon
that its poor old Ne5 that is up for the "knackers yard".
But how?! Both Nxg6 and Nd7 give up the knight for not
much benefit. Perhaps the simple Ng4, threatening Nf6+ is
all we need!?!
<23 Ng4 ...>
23 ... Nd7/Ne6
24 Nf6+ Kh8
25 Qxh7#
23 ... f6
24 Rxe7 mating
23 ... Re6
24 Nf6+ ...
24 ... Kh8
25 Rh3 Re1+
26 Bf1 dxc4
27 Qxh7+ Nxh7
28 Rxh7#
24 ... Rxf6
25 gxf6 Ne6
26 Rxe6 Qf8
27 Re8! mating
I don't see an alternative for black but to try to take Re3 and therefore as Nf6+ has to be allowed... <23 ... Rxe3>
<24 Nf6+ Kh8>
<25 fxe3 ...>
click for larger viewWhite has played a MASSIVE <GOOT>. The black king is in a mating net.
Nf8 is stuck defending against Qxh7#.
Pf7 is locked where it is.
Rb7 is blocked in by Bb7.
Bb7 is a bystander, without any influence on the game and is just in the way!
But worst of all Qa8 is not not capable of stopping the white's DSB from
ripping a hole in black's defences.
White on the other hand has a multitude of threats; Bxg6, Be5, Bd6 and Nxh7.
The most devastating of these seems to be <26 Be5> lining up the discovered check
sequence of <27 Ne8+> mating Time to see when Black resigned... |
|
| Nov-24-16 | | Caissas Clown: Hmmmm....I assumed the position was wrong because "With a Knight on F8 , there's never a mate" ! :-) |
|
| Nov-24-16 | | clement41: I considered mostly -kindof only- Nxg6. Ng4 escaped me; backward attacking moves are notoriously difficult for humans to find |
|
| Nov-24-16 | | zb2cr: I went for <An Englishman>'s line as well, but then saw that after 23. Nxg6, Rxe3; 24. Nxf8, Re1+ White's attack sort of fizzles out. 25. Bf1 allows Black to safely play 25. ... Qxf8. 25. Kg2 allows 25. ... dxc4+; 26. Kg3, cxd3; 27. Nxh7, Re6; 28. Nf6+, Rxf6; 29. gxf6, Qf8 and it looks like White has nothing better than a draw. So, nothing for me today. To all Americans on this site, Happy Thanksgiving! |
|
| Nov-24-16 | | Anjeneyar: instead of 25. Rh3 even the prosaic 25. Rxe6 wins for white.
25....fxe6. 26. Be5!mates in 2 more moves.
26.....Nd7. 27. Qxh7#
26. ...Bc6/8. 27. Nd7. Kg8. 28. Qg7#
26.....Qb8. 27 Nd7+. Qxe5. 28. Qxf8#

| Nov-24-16 | | Gilmoy: <Caissas Clown: "With a Knight on F8 , there's never a mate" !>
It's correct, and in fact it's the key to the puzzle! <While he <stays on> f8, he guards against mate> -- ergo, the trick is to force him to <move>. i.e. you need a <triple> attack on h7, which becomes a checklist item in your prep. [x] 1st attack: <19.Qh5 22.Qh6> [x] 2nd attack: <23.Ng4 24.Nf6> [~] 3rd attack: hmm maybe lift a rook? <20.Re3> yup [x] |
|
| Nov-24-16 | | PJs Studio: I guessed 25.Be5 because the rook must take and then after 26.Rxe5 nothing can stop Re8! Winning the queen. But I like 25.Rh3 even more. But, do I get an "F" for 25.Be5? |
|
| Nov-24-16 | | johngalt5579: I played the first move but did not see the follow up. |
|
| Nov-25-16 | | patzer2: Got so busy enjoying Thanksgiving with family and friends yesterday that I didn't take the time to solve this week's Thursday puzzle (23. ?). The threats created by 23. Ng4!  are clearly decisive, forcing mate-in-seven per Deep Fritz 15 @ 25 depth. P.S.: For a Black improvement, I'd start early in the opening. The data in our Opening Explorer demonstrates 3...c5 = is superior to 3...dxe4 4. Nxe4  in improving the second player's winning chances. |
