Apr-04-13  abuzic: <23...Rg8> was not the best shot for black:

23...Rg8 24.Ng5 Qxh4 25.Rc3 <instead of ...Nh3> Rxg5 26.Qf4+ Re5 27.Rh3 Qxh3 28.Qxe5+ Nxe5 29.Bxh3 and escape from heavy losses

Instead, black had the crushing 23...Be3!:

24.Nxf6 Bxf2 and the threat of ...Qg1# cannot be met without heavy material loss: like 25.e3 (or e4) ...Rd2 (or simply ...Ne3+ wins the Q);

24.Ra3 Nxe4 25.Bxe4 <(25.fxe3 Ng3+)> 25...Rg8, now white has to face the ...Qh1+ sac and # threat

<mike1: 25. Rxc6? bxc6, 26. Bxc6??> then 26...Nh2+ wins; perhaps better was 26.Qf4+ Kc8 27.Qf5+ Nd7 28.Rd1 Qxf2+ 29.Qxf2 Nxf2 30.Kxf2 Rxg5 31.Bxc6 with material advantage for black.

<25.Rxc6 Qxg5>?? black plays 25...Bxg5 26.Rc3 Bd2 (threat ...Qh1+) 27.e3 Bxc3 28.bxc3 Nh2+ 29.Kg1 Rg5 30.Ra4 Rxf5 31.Rxh4 Nf3+ 32.Bxf3 Rxf3 with material advantage.

Apr-04-13  cocker: 25 ♖c3 is White's best defence, when Black gets only small advantage of 2 knights versus rook.
Apr-04-13  morfishine: <Phony Benoni> Yes the game Ivanchuk vs Yusupov, 1991 was terrific; If I remember correctly, it was a playoff game; not speed chess, but shorter time controls; Also, if I remember correctly, in a CL article, Yusupov (or maybe it was Ivanchuk) had a somewhat 'ho hum' attitude towards this game since it was at reduced time control

Very exciting, nonetheless!

Apr-04-13  M.Hassan: "Medium"
Black to play 24....?
Black is behind. He has a Knight for a Rook and a pawn. The pawn can be compensated right away:

24...........Qxa4
Now, the knight on g5 is under attack by 3 Black pieces and is defended by Black Queen only. To be saved, has to leave g5 and that will help to open up the g file

<if 25.Nf3 Qxf2#>
if 25.Nxf7 Qh1+
26.Bxh1
now g file can be fully opened 26.........Nh2+
27.Ke1 Rg1#

Similar pattern can happen if Knight moves to h3
25.Nh3 Qxh3
26.Bxh3 Nh2+
27.Rg1#
Black should thank White for not having developed the e pawn at the opening stage!

  TheTamale: Funny. I gave up, thinking, "If I were Black, I'd probably just play 23) ...Qxh4." Had I kept looking, I might have actually solved a Thursday puzzle.

24...Qxh4 (not Qxa4).

Apparently you don't realize that <M.Hassan>'s queen has the power to travel in time. When she captures the bishop on a4, she's making the key move for the puzzle to be posted on 17 August 2021, beginning a combination that will culminate in mate in seven.

Apr-04-13  David2009: Xiu Deshun vs J Sriram, 2012 Black 24...?

This problem baffled me. Black is a piece down in the puzzle position and White threatens a6. I looked hard, couldn't see a forced win, so thought, "what would I play OTB?" and found 24...Qxh4 hitting the N which can neither move nor stay: but White has 25.Qf4+ Ka8 26.a6 with a dangerous attack: 26...Rb8 27.axb7+ Rxb7 28.Bxc6 looks very strong.

So I looked up the solution - and found Black did indeed play 24...Qh4 to leave

White fell for the sucker punch 25.Nh3 Qxh3 - so what happens if 25.a6 is played?

I finally discover 25.a6 Rxg5! meeting 26.Qf4+ with Re5 and White is busted. 25.Qf4+ first has no chance: 25...Ka8 26.a6 Nh2+ wins the Queen. Nice problem!

  Jimfromprovidence: <cocker> <25 Rc3 is White's best defence, when Black gets only small advantage of 2 knights versus rook.>

I agree with this assessment.

This is a tough move to find but after 25 Rc3, if 25...Rxg5 26 Qf4+ Re5 follows, now comes 27 Rh3!, setting up a queen exchange.

Apr-04-13  LJLMETAL: 26. Kg1, Qh2+
27. Kf1, Qh1+!
28. Bxh1, Nh2+
29. Ke1, Rg1# or

26. e3, Nxe3+
27. fxe3, Qxf5

Apr-04-13  YouRang: What a nice combo!

I got as far as thinking "If that white knight on g5 were to go elsewhere, then I could play ...Qxg2! followed by Kxg2 Ne3++ (double-check winning back the queen).

I couldn't see a good way to compel the knight to move (and still keep my tactic in force), so I quit. Even with this utter failure, I feel proud of finding a tiny part of the solution. :-\

Apr-04-13  M.Hassan: <SuperPatzer77:24...Qxh4 (not Qxa4).>

Many thanks for correction

I am a lay man!. Do not quite understand what is meant by the above paragraph. Please explain in simple wording.

  agb2002: Black has a knight for a rok and a pawn.

White cannot play 25.Nf3 because of 25... Qxg2+ 26.Kxg2 Ne3+ and 27... Nxf5.

The obvious move is 24... Qxh4 winning the knight because:

A) 25.f4 Qf2#.

B) 25.Ne4(xf2,h7) Qh1+ 26.Bxh1 Nh2+ 27.Ke1 Rg1#.

C) 25.Nh3 Qxh3

C.1) 26.Bxh3 Nh2+ 27.Ke1 Rg1+ 28.Bf1 Rxf1#.

C.2) 26.Qxf6 Qh1+ 27.Bxh1 Nh2+ 28.Ke1 Rg1#.

D) 25.Nf3 Qxf2#.

E) 25.Qf4+ Ka8 26.Rxc6 Qxg5 27.Qc7 Ne3+

E.1) 28.fxe3 Qxg2+ 29.Ke1 Qxc6 - + [B+N vs P].

E.2) 28.Ke1 Nxg2+ 29.Kf1 (29.Kd1 Qd2#) 29... Ne3+ 30.Ke1 (30.fxe3 Qg1#) 30... Nc2+ and mate next.

Apr-04-13  Patriot: Black is down the exchange and a pawn.

24...Qxh4 looks correct here.

25.Nf3 Qxf2#

25.Nxf7 Ne3+ 26.fxe3 Bxe3 27.Rc3 Qh2 28.Rxe3 Qxg2+ 29.Ke1 Qg1+ 30.Kd2 and I'm just not seeing it. 26...Ng4 looks very interesting.

I'm out of time on this.

Apr-04-13  howlwolf: I did not like this puzzle. I looked at it said to myself Qxh5 is the obvious move, the move I would play in the position otb, saw the mate if the knight on g5 moved with Qh1+ followed by Nh2+, but thought it can't be that obvious and finally gave up to look at the game.
Apr-04-13  Abdel Irada: <M.Hassan>: The post was a joke in response to <SuperPatzer77>'s correction.

Apr-04-13  M.Hassan: <Abdel Irada:M.Hassan: The post was a joke in response to SuperPatzer77's correction.>

That's what I gussed, but don't understand it and that's why I asked for explanation

Apr-04-13  Abdel Irada: The joke was that the move "Qxa4" was actually the solution to a future puzzle.
Apr-04-13  andyatchess: Where did white go wrong? It seemed like a hack attack from black.
Apr-25-17  Cheapo by the Dozen: So what could White have tried at Move 25?

25 Rh3 does not work, as 25 ... Qxh3 leads to a finish much as in the game.

25 Rg3 Qxh4 could lead to interesting complications. I haven't worked them through.
