| May-21-16 | | siggemannen: I also though the solution was Qxf3. |
|
| May-21-16 | | diagonalley: ....bordering on the "insane" for my money - though i did get the (wrong) first move! |

 | | scormus: <previous kibitz's> Yes, 36 ... Qxf3 looked like the move to me too. The sequence after 37 gxf3 is not so difficult to find, via some natural N moves with + and discovered +. However, W is not forced to take the Q. Well, not difficult once you've had the engine to show you ;) Adly must surely have seen the Q-sac possibility and may have tried to find the line, perhaps using the repeat moves to gain some time before choosing the more prosaic ... Rg3. Pity he didn't go for ... Qxf3! |
|
| May-21-16 | | patzer2: Great game by the Egyptian GM Ahmed Adly for our Saturday puzzle (36...?). According to the computers, Black's 36...Ng3+  (-3.52 @ 31 depth, Stockfish 290116) is winning. However, much stronger is 36...Qxf3! forcing mate. If White accepts the sham Queen sacrfice, the mate goes 36... Qxf3! 37. gxf3 Rg1+ 38. Bxg1 Bxf3+ 39. Rg2 (39. Bg2 Ng3+ 40. Kh2 Ne2+ 41. Nd6 Rxg2+ 42. Kh1 Ng3#) 39... Ng3+ 40. Kh2 Nxf1+ 41. Kh1 Ng3+ 42. Kh2 Ne2+ 43. Nd6 Bxd6+ 44. Kh1 Bxg2#. Black's 5...g6 (novelty?) makes this the only game in the chessgames.com database with this move, and it looks like a very playable alternative. For an improvement for White, the computers suggestion of ditching the prophylactic 10. h6 = in favor of the more active developing move 10. Re1  looks good. |
|
| May-21-16 | | Razgriz: Got Ng3+ but oh my I couldn't get a proper followup. |

 | | offramp: It looks like Ahmed Adly missed a brilliancy in the style of his namesake Al-Adli. Very very hard to see, especially when there was a safer alternative. |
|
| May-21-16 | | crabgrass: 51. ....... Rd2 is inferior to
Rb2+
52. Ka1 Ra2+
53. Kb1 R@h2 b2#
What am I missing? |
|
| May-21-16 | | morfishine: Anybody that claims they got all 36 moves is a liar :) I figured first 36...Ng3+, then 37...Nxf1, then 38...Qxf3 <crabgrass> White rook on <b6> ***** |
|
| May-21-16 | | WorstPlayerEver: Hmm.. kinda sure this puzzle is based on Qf3. Don't ask me how it continues; it's weekend :) |
|
| May-21-16 | | schachfuchs: How about something like 36...Ng3+ 37.Kg1 Ne2+ 38.Rxe2(?) Qxf3 and 39...Qxh3 ? Is this won or lost? And should white play 38.Kf2? |
|
| May-21-16 | | ndg2: 36...Qxf3 is the solution. Taking tge queen is mate in a couple of moves. OTOH, there are undefendable threats of Qxh3+ or Qg3,Qg2#. |
|
| May-21-16 | | Joseph Blackcape: Didn't think of playing Ng3, since Qxf3 looked interesting and showed unavoidable mate whether the Queen is taken or not. Both bishops firing at the white king's position, both rooks poised at the g rank, both cutting him off and ready to check and the knight ready to jump to g3, while most of the white pieces are too far away or getting in each other's way. All that remains is to remove the pawns blocking the access to the king. |
|
| May-21-16 | | mel gibson: < ndg2: 36...Qxf3 is the solution> Yes - this is one of the first I've seen where the published game has the wrong move. |
|
| May-21-16 | | The Kings Domain: Missed this one. Came up with 36)... Qxf3. Boy, black's pieces sure were primed for a kingside attack. |
|
| May-21-16 | | devere: I think that everyone will look at 36...Qxf3. What is harder to see is the followup move 37...Rg1+ that makes the mating combination work.

| May-21-16 | | kevin86: The queen sac wins it quickly! Too bad, black didn't see it and had to mate a slower way. This puzzle is an inverted Monday puzzle. The queen sac IS the solution, but even the master misses it. |

 | | Jimfromprovidence: I got 36...Ng3+ 37 Kh1 Nxf1 38 Rxf1 (38 Kxf1 Rxg2, seeing 39...Qxf3+) 38...f4!?
click for larger viewNow 39 Bd4 (forced?) e5.
click for larger viewWhite cannot play the bishop to f2 because of ...Qxf3, so white loses the bishop. (I think). |
|
| May-21-16 | | Aleman: Ok, its really complicated. Lets just not do anything crazy and play the sensible looking RG3. This can set up a nice sac on h3 or f3, the White king looks in trouble. Very hard to find a direct winning line though. |
|
| May-21-16 | | dfcx: I do not see any defense against
36...Qxf3
37.gxf3 Rg1+ 38.Bxg1 Bxf3+ 39. Bg2 Ng3+ 40.Kh2 Ne2+ 41.Kh1 Bxg2# If white plays
39.Rg2 Ng3+ 40.Kh2 Nxf1+ 41.Kh1 Ng3+ 42.Nh2 Ne2+ 43.Kh1 Bxg2# |
|
| May-21-16 | | agb2002: The material is identical.
I've considered a number of moves 36... Ng3+, 36... Rg3, 36... Rxg2, 36... Qxf3, 36... Nf4, 36... Bg3 and 36... Bf4 and found some interesting ideas like 36... Ng3+ 37.Kg1 (37.Kh2 Nxf1+ wins a piece at least) 37... Nxf1 38.Kxf1 (38.Rxf1 seems to be the only move) 38... Rxg2 39.Rxg2 Qxf3+ 40.Rf2 Rg1+ 41.Kxg1 Qh1#. I don't know. I'd probably try 36... Rg3. For example, 37.Nd4 Rxh3+ 38.gxh3 Ng3+ 39.Kg2 Ne2+ 40.Kh1 (40.Kf2 Nxd4 41.Qd1 -41.B(c)xd4 Qxf3#- 41... Nxf3 wins decisive material) 40... Qxf3+ 41.Nxf3 Bxf3+ 42.Bg2 Bxg2#. |
|
| May-21-16 | | agb2002: <Jimfromprovidence> It looks very elegant: 40.Ba7 Bxa7 41.Nxa7 Qb6+ wins the knight, 40.Na7 Qa6 wins a piece and 40.Bf2 Qxf3 41.Be1 Qxh3 followed by Kh8 seems to win. |
|
| May-22-16 | | stst: Try the Q-sac main line:
36...........Qxf3
(A) 37.gxf3 Rg1#
(B) 37.Rf2 Qxh3+; 38.gxh3 Rg1#
(C) 37.Kg1 (or, Re2 to add protection to g2, then Bh2+ and still Kf2, though later fleeing via e1 is possible) Qxh3+; 38.Kf2 Rxg2+;
39.Bxg2 Qxg2#
(D) 37.Rd7 Qxh3+; 38.Kg1 Rxg2+
39.Bxg2 Qxg2#
don't see other more effective "mating" net (could go longer than above...) |
|
| May-22-16 | | stst: after the game's line, after 42.Kf2, Black's Bg3+ will reap a R, up the exchange. |
|
| May-23-16 | | Moszkowski012273: Would definitely consider 36...Qxf3. But no way in hell would I ever think about playing the correct follow up (37...Rg1+) |
|
Sep-19-17
| | offramp: The combination that Black could have played here is similar to another famous unplayed combo: Karpov vs Chandler, 1983. |
