Aug-12-07  nimzo knight: <openingspecialist> Just for my better understanding, why would u call a1-h8 diagonal weak for black. It looks well controlled by bishop. Also about d7, it is controlled by three of black pieces.
Aug-12-07  Ashram64: lol.. surprisingly I the whole line up to Bb5, not bad for a Sunday puzzle. The point is the f7 weakness

  Amulet: That heroic pawn on the d-file did a fantastic job of holding up the opponent. A medal should be awarded that brave pawn!
Aug-12-07  realbrob: I got the first 3 moves pretty easily (though not in 5 seconds like <ARK84>), I admit I didn't look further because I didn't have time...
Aug-12-07  LivBlockade: <ravadi:> I think that after 22. ♖xb6 ♖xe2; 23. ♖xe2 axb6; 24. ♕c4 looks strong. For example, if 24...♕d7; 25. ♖e7 or if 24...♗e6; 25. ♘xe6 fxe6; 26. ♖xe6 seems hard to stop.
Aug-12-07  BipolarChessorder: Got the initial xchange sac and the subsequent attack on f7, but not much further - 26.Bb5! is very elegant. The queen can't budge and even 26...Rf8 leads to a forced mate on f7 (27. Bxd7 Rxf4 28. Bxe6+ Rf7 29. Bxf7 mate)
Aug-12-07  Soltari: Wow I solved my first sunday ever, not that I really solved it, but somehow I guessed all moves correctly. I guess I just got lucky :].

  fm avari viraf: After a quick glance, I spotted the Black's "Achilles Heel" f7 but how to exploit it? Since the c4 is guarded with the Knight & of course, the Black Bishop is ready to grab the Rook on b1. Therefore, 22.Rxb6 axb6 23.Bc4 here Black has two choices either 23...Be6 or 23...Rxe1+ The former would invite White to play another exchange sac 24.Rxe6 whereas the latter 23...Rxe1+ 24.Qxe1 Bf6 25.Bxf7+ Kh8 26.Bd5 Bd7 27.Qe4 with winning chances.

  Fusilli: Well... I got the whole thing but I thought Black had 26...e5 in the actual final position of the game. Now I see that White ends up with an extra piece and a winning endgame after 27.Bc4+ Re6 28. Qg4 R8e8 29.Bxe6+ etc. Or 27. Qf3 e4 28.Bc4+ (28.Qf4 Be5) Re6 29.Qb3.

Since I thought Black would save the day with 26...e5, I thought of 25. Bxe6+ Rxe6 26.Qc4 Bg7 (what else?) 27. Nxe6 Bxh6 28. Nd8+ and various continuations that I thought were winning for White. I can show some lines, but now I see there are refutations and White can only hope for perpetual check.

All this said: 1) I would have played moves 22, 23 and 24 in real life since I thought they were winning, 2) Given this, I hope I would have seen that 26...e5 does not work once I got closer to it, 3) therefore, using a logic that it's probably much sounder than <ARK84>'s, I solved it in 3 seconds, since I saw Rxb6 in 3 seconds (2 seconds faster than <ARK84>!), and I would have played it anyway (after all, we all know that's what <ARK84> means, not, of course, that he/she saw the whole thing, including why 23...Rxe1+ does not work and why 26...e5 does not save Black, in 5 seconds. What he/she did was *guess* that Rxb6 was the first move of the solution, which of course does not count as "solving the puzzle.") In my case, the rest of the analysis until I felt confident that I would play Nxb6 in real life took me a half hour.

Did those who solve it see 26...e5 in the final position and why it doesn't work?

BTW, I burned 200 calories working on this! To work on the hard puzzles I set up the position and get on my eliptical work out machine... pedal and pedal until the ideas get to the brain! I recommend it to everyone!

Aug-12-07  Nasruddin Hodja: <LivBlockade>: Though Chiburdanidze's combination was inspired, I don't think Malaniuk adopted the best defense, especially since he had to resign four moves later. He was much better off by making a countersacrifice:

22. Rxb6! Rxe2 23. Rxe2 Bd3 24. Re3 c4! 25. Rb5 Rxa2

and black has counterplay against white's f2. Which probably does not compensate him fully for being a full rook down, but imo is better than resigning on move 26. I don't know if it's me, but it seems a lot of people resign prematurely when they could still fight on to try to swindle their opponent out of the win.

  patzer2: For today's difficult Sunday puzzle, White initiates an attack on the weakened King side by removing the guarding Knight via the deflection exchange pseudo-sacrifice 22. Rxb6!! on the Queen side, which enables 23. Bc4 and entices 23...Be6.

The follow-up exchange sacrifice 24. Rxe6! continues the theme of using deflections to remove the guard in order to continue pushing the attack with 25. Qf4.

The final deflection 26. Bb5 removes the guarding Queen for a now obviously decisive mating attack.

Aug-12-07  Guguni: 24... R:e6 looked more logical for black. At least the deflecting white bishop would be traded off.
Aug-12-07  LivBlockade: <Nasruddin Hodja:> ♖e3 does not look best in your line. I'd prefer ♖e7. So after 22. ♖xb6 ♖xe2; 23. ♖xe2 ♗d3; 24. ♖e7 axb6 (what else?) White's position still looks very strong. For example, after 25. d7 ♕c6; 26 ♕e3 threatens both ♕xd3 and ♖e8+.
Aug-12-07  Nasruddin Hodja: Hmm. After 22. Rxb6! Rxc2!? 23. Rxe2 Bd3 24. Re7 white doesn't yet have mating pressure so black can continue with 24. ... c4 25. Rb4 Qc5 26. a3 Bd4 27. Ne4 Qc6. Mostly academic, since white will still win with good defense, but I still think that it's a better continuation than Malaniuk's acceptance of the exchange sacrifice.
Aug-12-07  Atwode: I think to claim full credit for solving this you would have had to have found the line 22.Rxb6 axb6 23.Bc4 Be6 24.Rxe6 Rxe6 25.Nxe6 fxe6 26.Qe3 Kf7 27.Qf3+ Kg8 28.Qe4 Kf7 29.Bxe6+ Qxe6 30.Qxb7+ Kf6 31. Qxa8 and White wins the Black bishop.
Aug-12-07  SpecialK: Rxb6 does stick out -- that knight is the key defensive piece! Glad to have found this, and the next few moves.
Aug-13-07  D4n: Tricky, tricky, tricky.

  kevin86: White's main focus on f7 and f8. All he needed to do was eliminate/divert enemy forces guarding the two vital squares.

Black was busier than a one-armed paper hanger and eventually the defense broke down.

  morfishine: <22.Rxb6> sacrifices the exchange to remove the guard, nothing pseudo about that (nor is this a deflection)

<24.Rxe6> is another exchange sac that removes the guard (this is also not a deflection)

<26.Bb5> is however a nice finishing deflection tactic forcing the Black Queen away from <f7>

  RandomVisitor: 19...Bf5 20.Rb5 c4 or 19...Bd7 20.Bh6 Qc6 and black is even.
