White's Ng5 is doubly attacked by black's Q+R battery, and it can't move due to the pin against ...Qxg2#. However, the white knights control the 7th rank above black's king, and this is exploited with <23.e6!>, which frankly is the only move that stands out.

We fork the Nd7 and the Pf7, and threaten e7+. More importantly, white threatens the deadly Qd6+. The immediate threat is Qd6+ forcing ...Ke8, then Qe7#. What can black do?
- Take the Ng5 <23...Qxg5> (threat ...Qxg2#) <24.e7+> forcing <24...Ke8 25.Nd6+ Kxe7>

Now 26.Rfe1+ forcing black to lose the Q (e.g. ...Kd8 Nxf7+ forking K+Q). - Create room on g8 with 23...Rg7, but then 24.Qd6+ Kg8 25.Ne7+, forking K+Q. Kinda easy Thursday. |

| Mar-23-17 | | ChessHigherCat: Poly-Anas' immortal. White obviously has to do something fast to get out of black's killer attack. I thought it might be Nh6 attacking the rook and f7 three times, forcing 23...Rg7, but unfortunately that solves white's problems. The game line 23. e6 is perfect because if 23. ...Nf6 or f6 24. Qd6+ Ke8 25. Qe7# and we all know what happens if 23...Qg5 |

| Mar-23-17 | | Walter Glattke: 23,Rfe1 Qxg4 24.e6 Qxg2# or Qxf4
but 23.e6 Qxg5 24.e7+ Ke8 25.Nd6+ Kxe7
26.Rfe1+ Kd8 27.Nxf7+ Kc8 28.Nxg5 wins.
23.e6 f6 24.e7+ Ke8 25.Nd6+ Kxe7 26.Rfe1+ Kd8 27.Ne6+ Ke7 28.Nf5+ Kd8
29.Re7 seems to win. |

<<+> Ana* Ana, Ana <+>> Not infrequently, a puzzle solution comes because a certain piece, square or move stands out from the position, almost as if it were outlined in fire. This time, that move is <<+> 23. e6! ... >, to which I see no better reply than

There are possible deviations, but all of them appear to be even worse for the second player. . *"Ana" is Arabic for "I" or "me."

| Mar-23-17 | | agb2002: White has a knight and a pawn for a bishop.
Black threatens Qxg5 followed by Qxg2#.
If the e-pawn were on e6 White would deliver mate in two with Qd6+. This suggests 23.e6: A) 23... Qxg5 24.Qd6+ Ke8 25.exf7+ Kxf7 26.Nh6+
A.1) 26... Kg7 27.Nxg8 Rxg8 28.Qxc6 + - [R+P vs n] (28... Ne5 -threatening Nf3+ and Qh4#- 29.Qxd5). A.2) 26... Ke8 27.Rfe1+ Kd8 28.Nf7+ Kc8 29.Qxc6+ Kb8 30.Nxg5 is a massacre. B) 23... fxe6 24.Qd6+ (far quicker than 24.Nh6+ and 25.Nxg8) 24... Ke8 27.Qe7#. |
|
| Mar-23-17 | | agb2002: The text 24.e7+ is much stronger than my 24.exf7+, which is also winning according to Stockfish. |
|
| Mar-23-17 | | AlicesKnight: 23.e6 looks like a big threat, with the attack on the N linked to Qd6+, a R intervention on the K file and possible Nh7+ (if e.g....Qf6), but the g2 mate must be watched. Let's see - yes, the right idea. |
|
| Mar-23-17 | | Once: <agb2002: The text 24.e7+ is much stronger than my 24.exf7+, which is also winning according to Stockfish.> Yes, I looked at 24. Qd6+ too. As you say, it also wins but not as quickly as 24. e7+. |

|
| Mar-23-17 | | saturn2: I saw the basic moves but had a different order, maybe because subconsciously I did not want to sacrifice the knight on g5. 23 Nh6 (Rh7 what else?) and only now
24 e6 Nf6
25 Qd6+ Ke8
26 exf7+ etc |
|
| Mar-23-17 | | saturn2: Damn. Null points because of 24..QxNg5 |
|
| Mar-23-17 | | clement41: 26...Kd8 27 Re8+? Kc7 28 Nb5+ would lead nowhere after 28...Kb6  (28...Kb7?? 29 Qc7+ Ka6 30 Qxc6+ ) |
|
| Mar-23-17 | | mel gibson: Should have been a Monday puzzle. |
|
| Mar-23-17 | | stacase: Once you see that White's Pawn can advance to e6 and fork Black's Knight and Pawn and get away with it, there's no other move to consider. Because it's going to get ugly for Black. |
|
| Mar-23-17 | | The Kings Domain: Missed this one, my choice was 23) Nxf7. Impressive win and good puzzle. |
|
| Mar-23-17 | | Carlos0012358: Things get rough for black after 26.Re1+
26...........Kd8
27.Nxf7 with a Fork
27...........Kc8
28.Nxg5 black looses his Q
28...........Rxg5
29.Qxg5 black looses to R
And white is up a Q and a pawn, and has R for N and B |
|
| Mar-23-17 | | BOSTER: < Abdel Irada : to which I see no better reply than 23...Qxg5>.
What about 23...Ne5? |

<BOSTER: < Abdel Irada : to which I see no better reply than 23...Qxg5>. What about 23...Ne5?> If 23. ...Ne5? 24. Qxe5, Qxg5 25. Qd6+, Ke8 26. Qxc6+, Kf8▢ 27. Qxa8+, Qd8
28. Qxd8#.

| Mar-23-17 | | YouRang: <agb2002: The text 24.e7+ is much stronger than my 24.exf7+, which is also winning according to Stockfish.> Hmmm, but you didn't have 24.exf7+ -- you had 25.exf7+. I think you meant that 24.e7+ was stronger than 24.Qd6+. |
|
| Mar-23-17 | | Marmot PFL: 23 e6 is obvious but then I went with 24 Qd6+ and 25 ef7+. Winning, but not as good as the game. |
|
| Mar-23-17 | | BOSTER: < 23.e6 is obvious>.
But better if you understand that this push not only open the line for white queen to attractive d6 square
, but at the same time break the communication between the black queen and d6 square. |

| Mar-23-17 | | RandomVisitor: After 20.h4, 20...g5 is not best, perhaps

| Mar-23-17 | | stst: Purely visual...
Both e6 and Nd6 are more meaningful starting moves for 27.
(A)27.e6 is annoying, if fxe, 28.Nd6 dis+ is dreadful;
if ... Qxg5, e7+ followed by Qxf7#
if ... Ke8, exf7 forks K&R
(B)27.Nd6 Kg7 may escape... |
|
| Mar-23-17 | | swclark25: Shoot...I looked at pushing the pawn but opted for Nge6+. Yesterday, I was convinced the pawn push was better but the Knight move was better! |
