Yes, I call that <DDD - Destruction, Deflection, Decoy>.
After 43 f4, Black wins with 43 ... xe5! 44 xe5 xg4+ and 45 ... xe5. 43 ... xe5! <DESTROYS> the White e5-knight which defends the g4-forking square. Then the recapture 44 xe5 <DEFLECTS> the White queen from defending the g4-forking square while simultaneously <DECOYING> her onto the e5-square for the upcoming Black knight fork on g4.
This tactical motif occurs when you have <a knight defending a knight fork square>. Here the White e5-knight defends the g4-forking square of the Black f6-knight.
<Knight defender means attack the defender, REMOVE THE GUARD!> Larsen does -exactly- this with 42 ... a1! and Reshevsky is forced to resign.

Yes, 26 b4? xh3! shows that Larsen was very tactically alert.
Now 27 gxh3? loses to the <DOUBLE ATTACK> 27 ... g5+, exploting the White c1-rook that was made <LOOSE> by 26 a2-b4?.
And if 27 xc8+, then Black has the nifty <RUBBERBAND> recapture 27 ... h3xc8, and Black has grabbed a pawn for free.
|Jul-31-07|| ||tpstar: After 41. Nxe5, note the combination had to start with 41 ... Rxc2 42. Bxc2 and then 42 ... Qa1! sets up the Family Fork. The immediate 41 ... Qa1 lets White try 42. Qf4!? as 42 ... Qxe5?! loses the exchange because the Rc7 is hanging (43. Qxe5 Nxg4+ 44. Kh1 Nxe5 45. Rxc7), or 42 ... Rxc2 43. Qxf6 and suddenly White has potent threats against Black's King.|
|Jan-18-09|| ||perfidious: While 26.Nb4 cost a pawn, the psychology behind this error illustrates the difficulty of playing when one lacks active possibilities-trying to exploit the weakness at c6 was all White could do, really.|
In John Nunn's collection of his best games, he publishes a win vs Azmaiparashvili in which he notes that even a strong GM can find it easy to go wrong in a position that, while worse, isn't clearly lost, yet is hard to improve in any way.
|Dec-13-09|| ||RandomVisitor: 40.Qg1 avoids this whole mess...|
|Dec-13-09|| ||An Englishman: Good Evening: Now this is more like it--a Sunday puzzle I couldn't solve. I think you have to see the last move of the combination to claim full credit, and I didn't even come close.|
|Dec-13-09|| ||Dr. J: I thought I had the solution with 40 ... Rxc6 41 dxc6 Nf6 winning in all variations (some of which are quite nice), but on closer inspection I found 41 Rxc6 Nf6 42 Rxf6 with what looks like about an equal game. Oh, well.|
|Dec-13-09|| ||dzechiel: Black to play (40...?). Material even. "Insane."
It seems the real weak spot in white's game is g4. This square is already under attack by black, but what black would really like is to have that square under attack by a knight.
The first candidate move I considered, 40...Nf6, does just that. But it also allows white to play 41 Nxe5, picking up a pawn AND defending g4. I think that black must first eliminate the knight, and then come in with his own.
Just glancing at the position, I think we will capture white's queen, then allow him to promote a new queen, but one that is far removed from the action, and we will have time to corral the white king.
Let's see how this all works out...
Why take with the rook instead of the bishop? Because I want the bishop to "lend a hand" on g4.
Perhaps better is 41 Rxc6 allowing black to get back the exchange with 41...Bxc6 42 dxc6. The reason I think capturing with the rook is a good idea, is that the rook then covers f6 and if black tries 41...Nf6 white can give back the exchange with 42 Rxf6 Qxf6 and I don't know where black will get an edge. But after the pawn capture we can go with
41...Nf6 42 cxd7 Nxg4+ 43 Kh3 Nxe3
OK, note here that white doesn't have time for 44 d8=Q because of 44...Qh1#.
I dunno, this position is "insane", which means I'm probably on the wrong track (but I really do like the removal of the knight as the key move).
I'm gonna peek and see how this game went down.
Some good ideas, but the wrong implementation. <sigh>, looking forward to Monday.
|Dec-13-09|| ||Dr. J: <RandomVisitor: 40.Qg1 avoids this whole mess...> After 40 Qg1 Qd3 Black still seems winning, e.g 41 Qb1 Bxc6 42 dxc6 Rxc6 43 Rb2 Qe3 (threat ... Rc1+) 44 Rc2 Qxe4 or 44 Bc2 Nf6|

40. Qg1 Qd3 41. Nxe5 and white is the one who is winning.
|Dec-13-09|| ||Jimfromprovidence: I saw 40...Nf6, threatening 41...Nxg4 and mate; then I tried 41 Qg1 as a defense.|

This fails as black wins after 41...Qg4+ 42 Kh1 Nxg4 43 Ba2 Bxc6 44 dxc6 Rxc6.

Now white is stuck. He cannot move his rook off of the second rank because if 45 Rxc6, for example, 45...Nf2+ wins the queen.
But he also has no safe squares along the 2nd rank to move the rook to because of the threat...Rc1.
|Dec-13-09|| ||cyclon: At firs sight it does not look like that WHITE is quite immediately losing something (a piece to begin with) in this position, but WHAT ELSE he can play after 40.-Nf6? Anyway, well played by Black against his (also) strong opponent.|
|Dec-13-09|| ||Check It Out: <40...Rxc6> to eliminate the knight from taking on e5|
<41.dxc6 Nf6 42.cxd7>
other moves seem to get white mated, [e.g. 42.Qc1 Nxg4+ 43.Kh3 Ne3+ 44.Kxh4 (44.g4 Bxg3+ 45.Kxh4 Qh3+ 46.Kg5 Qh5+ 47.Kf6 Qh4+ 48.Kxf7 Bh5+ 49.Kf8 Qd8# is a cool king hunt mate) Qf4+ 45.Kh5 Qg4#]
<42...Nxg4+ 43.Kh3 Nxe3 44.Kh2> to prevent Qh1#
<44...Ng4+ 45.Kh3 Nf6 46.Kh2> again to prevent mate
<46...Nxd7> eliminating the dangerous d7 pawn and leaving black up a queen and two pawns for rook.
There are many variables here but I'm excited to check this one out...
Larsen's way is so much simpler; 42...Qa1 is killer, there is no way to avoid losing the knight. I looked at 40...Nf6 and disregarded it due to 41.Nxe5; figuring I should just eliminate the white knight before Nf6 led me to consider 40...Rxc6.
I am disappointed on this one, and would appreciate some analysis on the lines I posted to see if any of it would actually hold up. Thank you in advance.
|Dec-13-09|| ||Check It Out: <Dr. J: I thought I had the solution with 40 ... Rxc6 41 dxc6 Nf6 winning in all variations (some of which are quite nice), but on closer inspection I found 41 Rxc6 Nf6 42 Rxf6 with what looks like about an equal game. Oh, well.>|
|Dec-13-09|| ||WhenHarryMetSally: i dont like 41. Nxe5 I rather prefer 41. Qg5.
But for a n00b like me I think i did pretty well for this puzzle.
|Dec-13-09|| ||remolino: Did not find it. Removing the knight on the first move did not work in any variation, and I spent 15 minutes on it. Then after 40...Nf6 Nxe5 I stopped analyzing too quickly.
...Qa1 is a great resource.|
|Dec-13-09|| ||newzild: Missed it. A brilliant combo.
I went for 40.Rxc6 de 41.Nf6
6/7 this week...
|Dec-13-09|| ||goodevans: White's K is short of squares but apart from that his position looks pretty solid and he looks to have a bit of an edge positionally with those nice central pawns. His only real weakness is the Pg4 and if I could take with N then there threats of both fork and mate.|
The immediate 40 ... Nf6 doesn't seem to work because of 41 Nxe5, so what if I take the N first. I want to keep my B (it's attacking g4) so ...
<40 ... Rxc6 41 dxc6 Nf6>
Now let's look at the obvious moves first ...
<42 cxd7 Nxg4+ 43 Kh3 Nxe3 44 d8=Q Qh1#>
I've been looking at this for a while now and I can't see any big improvements for white. Rc1 at some point would help but I can't find time for him to fit it in.
I think I'm on the right lines but the detail is just too much for me right now!
Let's check ...
|Dec-13-09|| ||goodevans: Not right, but I see I'm in very good company with my incorrect solution!|
|Dec-13-09|| ||cyclon: <WhenHarryMetSally: i dont like 41. Nxe5 I rather prefer 41. Qg5> After 41.Qg5 follows; -Nxg4+ 42.Kh3 Nf2++, and now either 43.Kxh4 or Kh2 gets -Qh1X. So, it`s either a Queen or Mate.|
|Dec-13-09|| ||cyclon: <WhenHarryMetSally: i dont like 41. Nxe5 I rather prefer 41. Qg5.> Sorry, my previous analysis is INCORRECT, because 1. There is even shorter Mate by (41.Qg5) -Nxg4+ 42.Kh3 Qh1X 2. In the faulty continuation 41.Qg5 Nxg4+ 42.Kh3 Nf2++? 43.Kxh4 Qh1+ is NOT Mate; 44.Kg3, but -Nxe4+ forks the Queen. Huh, how the small world expands!|
|Dec-13-09|| ||Tifeon: How bad am I? I excluded 40...Nf6 from my analysis just because 41. Rf2 caught my eye first. Is f7 pawn dead? Of course not, since 41...Nxg4+ 42. Kh3 Qh1 mates. But I thought my first impression is so good, I never thought about the obvious solution.|
Anyway, I spent too much time on crazy moves like 40...h3? or 40...f5?? Then I settled for 40...Nd6 - a move that simply loses to 41. Rf2 Qa1 42. Rf6. First impression again!
OK, the only thing that may explain my miscalculations is that I spent only 2 minutes studying this. Not good explanation anyway.
|Dec-13-09|| ||sethoflagos: With no immediate threats to the black K or pieces the action seems to centre around the en prise pawns at e5 and g4. Good threats for black are a potential Qxg2# or the royal fork from Nxg4+. White can attack BQ with Rc1, advance the passed pawn at d5 or exploit defensive weaknesses on the sixth and seventh ranks.|
An initial 40 ... Bxg4 41 Nxe5 looks lousy so let's start with the knight.
40 ... Nf6 threatening Nxg4+
41 Nxe5 Rxc2 threatening Qxg2#
42 Bxc2 Qa1 if N moves Nxg4+ wins Q,
if Qf4/g5 Qxe5 also wins N
If 41 Rc1 Nxg4+ 42 Kh3 Nxe3+ 43 Kxh4 Qf4+ and rapid mate
If 41 d7 Nxg4+ 42 Kh3 Nxe3+ 43 Kxh4 Rxc6 and overwhelming advantage
If 41 Qc1 Nxg4+ 42 Kh3 Ne3+ 43 Kxh4 Qf4+ Kh5 44 Qg4#
If 41 Qh3 Nxg4+ wins Q
If 41 Qg5 Nxg4+ 42 Kh3 Qh1#
Time to see
