Apr-06-13  stacase: 27 ... Ng4 and White resigns was good enough for me, I didn't linger to worry why. But on coming back to this page to read other comments I got curious after <Jamboree's comment>. Black's Queen and Knight are going to form an "Old Mill" and tear the place up, sort of softening the beach before Black's Rook shows up on a3. It can't be pretty for White.

Brilliant moves!

Apr-06-13  Patriot: White has the bishop pair and a pawn.

Due to the x-ray of Ra8-Qa4, the key is likely 25...Nc5 and a double-attack on e4. 26.Qc2 and possibly 26...Ra2 27.Qxa2 Nxe4 but I don't see anything winning for black. 28.fxe4 Nxe4 -- a mistake would be 29.Bxe3 Qxe3+ 30.Kh1 Nf2+ etc. with a smothered mate. This looks strong though since 29...Nxf2 with a discovered check threatened.

I'm out of time.

Apr-06-13  Patriot: I was wrong on the smothered mate theme since after 31.Kg1 Nh3+ 32.Kh1 Qg1+ 33.Nxg1, the queen guards f2.

Close but no cigars. I didn't really appreciate the strength in 26...Ncxe4 27.fxe4 Ng4 after calculating this possibility.

Apr-06-13  David2009: V Tukmakov vs E Magerramov, 1983 Black 25?

Level material. Try 25...Nc5 26.Qc2 Ncxe4 and if 27.fxe4 Ra2 GOOT!. If 28.Qxa2 Nxe4 GOOT2! Time to check:
=====
Missed it - the game line is clearly more efficient. I had the same optical illusion as <al wazir>: <26...Ra2 27.Qxa2 Ncxe4 28.fxe4 Nxe4 29.Bxe3 Qxe3+ 30.Kh1 Nf2+ 31.Kg1 Nh3+ 32.Kh1 Qg1+?? 33.Nxg1 Nf2+ 34.Qxf2> Somehow it is difficult to see that, with two pieces in the way of the Qa2 guarding f2, the Q will nevertheless end up guarding f2 because the other two pieces move out of the way. So Black would have to take the perpetual check.

The combination is also unsound because instead of Qxa2 drawing White who is a piece up could play for a win with Qd3!.

It's mostly gibberish and is amusing for the first 15 times you see it. After that it's just worth ignoring. Don't mean to be mean but this is an English speaking forum so to post you need at least some broken engish to communicate.

  FSR: I dunno. I just see the face-hanging line that I notice that <al wazir> gave.

  FSR: Silly me. I had seen the possibility of playing one knight to e4 and then the other to g4, but only after (quite pointlessly) sacking the rook on a2. It turns out that Black doesn't mate at all, just secures a decisive material advantage with his "windmill" knight.
Apr-06-13  Archswindler: <MostlyWatch: If this is taboo, forgive me because I'm new here, but I don't understand, chrisowen, what you write. Are you crazy or are you writing in code? Anyone?>

I'm guessing crazy. Sane people post gibberish on occasion, but I think you have to be quite special to do it 3000 times and not get bored.

Apr-06-13  BOSTER: After 25...Nc5 26.Qxa8 Rxa8 27.bxc5 the black brilliant combo is disappeared and game is equal! (almost).

Apr-06-13  Patriot: <BOSTER> I would at least play 26...Bxf2+ in that line so that 27.Kxf2 Ncxe4+ 28.fxe4 Rxa8 gets a little more material.
Apr-06-13  James D Flynn: Black is a pawn down but the discovered attack on the White Q will enable him to bring another N into the attack by Nc5. That may be played either before or after Bxf2+ because if White exchange Bs and retreat6ts his K to h1 he is in danger of smothered mate e.g 25…..Nc5 26.Qc2(not Bxe3 Qxe3+ 27.Kh1 Nxa4 wins the Q) Ncxe4 28.fxe4 Ng4 29.h3(there is no defense for the b and if Bxe3 Qxe3+ leads to smothered mate) Nxf2 30.Kh2 Nxd1 31.Rxd1 Ra3 Black is the exchange up and will penetrate decisively doubling his Rs on the a file.
Apr-07-13  Abdel Irada: <<•>Harmonic convergence?<•>>

Some combinations appear forward, others backwards. This one came to me in the form of a daydream: <If I could play ...Ng4, I'd be able to set up a windmill attack>. From there, all the moves fall into place.

<<•> 25. ...Nc5 >

Hail the Improbable Knight, an unlikely protagonist born in the far hinterlands of the queenside on a suicide mission into enemy territory on the kingside front. Of course White can't take the knight, and exchanging queen for rook and knight looks dubious at best, and that assumes Black has nothing better to do than make the "obvious" recaptures.

<<•> 26. Qc2 ... >

The queen can also move to b5, but this merely takes it further out of play.

<<•> 26. ...Ncxe4! >

Now this is a sacrifice, and White has nothing better than to accept it, since now his bishop is twice attacked and can be taken with check, and if White exchanges on e3, the black queen recaptures with check and White is in a bad way.

<<•> 27. fxe4, Ng4 >

Now this is the point: Black still has two attackers on f2, and will simply take a bishop for nothing on any neutral move.

White has only one "counterattacking" move, and it's a bust: (a) 28. h4?, Qxh4 and mate is inescapable.

This means it's submit to the windmill, in one form or another, or suffer worse, so let's continue with the resulting "main line":

<<•> 28. Bxe3, Qxe3†

29. Kh1, Nf2†

30. Kg1, Nxd1† >

We must not now fall for the Great Smothered Mate Illusion: 30. ...Nh3†† 31. Kh1, Qg1†? 32. Nxg1, and suddenly we find that the intended "mate" doesn't work because the queen on c2 now watches f2.

<<•> 31. Kh1, Nf2†

32. Kg1, Nxe4† >

Black is already the exchange and a pawn ahead, and will soon bring in more forces (via ...Ra3 and Rfa8) to mop up any remaining resistance.

(I am being a bit lazy since I'm already posting late. On this occasion, I am looking principally at the "main line," with only tangential references to alternatives. However, when the alternatives seem no better for the defender than does the main line, I am not persuaded that this is a critical omission.)

Apr-07-13  M.Hassan: "Very Difficult"
Black to play 25....?
Black is a pawn down.

I had the right idea to attack the Queen by a discovered check:

25............Nc5
26.Qc2 Nxe4
27.fxe4 Ng4
(this was where I went wrong doing 27...Bxf2+)
28.Rb3 Nxf2
29.Rdb1 Ne4+
30.Rxe3 Qxe3+
31.Kh1 Nf2+
32.Kg1 Kg7
33.c5 Rh8
34.Qd2 Qxd2

<if 34.Qc1 Nh3++ 35.Kh1 Qg1+ 36.Nxg1 Nf2#>

White looses the Queen and Black wins.
