Mar-24-07  TrueBlue: saw the key moves for black rxh3 followed by Rh8+ and Rh3+, not that hard. Yesterday's was much harder for me.
Mar-24-07  dzechiel: Wow! Got the first move, of course (I'm sure eveyone did/will), but sacrificing the first rook to clear your own pawn out of the way, and the second rook to allow the queen to enter with check is inspired!

It's mate after 33 Kxh3 Qh5+ 34 Kg3 Qh4+ 35 Kf3 (35 Kg2 Qh2#) Qh3#.

Outstanding play by Kochyev!

Mar-24-07  chessmoron: Double rook sacrifice in this game is very pretty. Took me 2 minutes on this gem.
Mar-24-07  think: So why didn't 31. ... Qh5+ work? All Rh1 then Rh3 did was reach the same position with black down a rook and a pawn.
Mar-24-07  Maz: cause of Kg2 then Kf3
Mar-24-07  Tactic101: Finally, I get a puzzle I can solve. Maybe this week wasnt' so bad. ;) Posted a puzzle in the Kibitzer's Cafe. You might want to solve it as well. Click here: The Kibitzer's Café
Mar-24-07  mpl: The problem with 31. .. ♕h5+ is that white is not forced to take the g3 pawn (32. ♔xg3? ♕h4+ 33. ♔g2 ♕h2+ 34. ♔f3 ♕h3#), but can escape instead via g2, f3 and use the g3 pawn as safeguard.

After 31. .. ♖h8+ 32. ♔g2 ♖h2+ 33. ♔f3 the black queen can make use of the long diagonal from the queen side with 33. .. ♕b7. This makes a winning difference ;)

But I didn't find the solution neither, because I was stuck in calculating the consequences of 31. .. ♕h7+ 32. ♔g2 Th8 which might lead to win also (33. ♔f3 g2 34. ♕xg2 ♕b7+), but not as clear as in the actual game.

Mar-24-07  ahmadov: I found the idea, not the solution...
Mar-24-07  Fisheremon: Another solution 28...Kb8 29.Rh1 Qd7 etc.

At 31 move 31...Qh7 also gives a clear win: 32.Kg2 Rh8 33.Kf3 g2 34.Qxg2 Qb7+ 35.d5 Qb3+

At 27 move Black could have a quicker win 27...Qh7!

White's mistaken twice:

19.Nf2? (19.Ng5!?) Here Black missed 19...Nxf2!. Also 20...Bb7?! cos' 20...Nxf2 still available.

24.Nd4? (24.Kxh2!? could save) after that the position was totally lost as 27...Qh7! could show.

Mar-24-07  eblunt: I had 28 .... Nf2 which I think is winning as well. After the same pawn sequence as above, the crux is 31 Nxf2 g3xf2 32 Qxf2 Rdg8+ 33 Kf1 Rh1+ 34 Ke2 Qh5+ 35 Qf3 Rg2+ 36 Ke3 Rh3 pinning the queen and winning

  mig55: eblunt, how do you go further after 29. c6?
Mar-24-07  kewlmodee: What would 31. Rc7+ Qxc7 32. Kxh3 Rh8+ lead to? Can white escape?
Mar-24-07  kewlmodee: Although 31. Rh1 looks better
Mar-24-07  delterp: <dzechiel>, minor problem with your line. 35 ♔g2 does not mate with 35...♕h2.
Both f1 and f3 are flight squares for the king that prolong the mate by 1 move.

36 ♔f1 ♕h8#
36 ♔f3 ♕h3#

Mar-24-07  dzechiel: <delterp> Thanks for keeping me honest!
Mar-24-07  JohnnyPawn: <delterp> Obviously you meant 36 ♔f1 ♕h1#.

  Richard Taylor: I saw this immediately but I wasn't confidant it looked too obvious. I thought White had something by sacrficing on c7 but couldn't see anything so the best I could see was the move as played although I thought the Q check on h5 won more quickly.
Mar-24-07  LIFE Master AJ: I set myself a time limit of five minutes. (I did not get it.)

I saw the first Rook sack almost instantly, I never even seriously considered the sacrifice of the second Rook.

Mar-24-07  LIFE Master AJ: Nice problem.
Mar-24-07  ALEXIN: I tought 28.Qb7

  kevin86: A neat rook sac-and it was good that black could survive the white attack.

  FSR: Very nice game by Kochiev.
Dec-29-18  mrknightly: Apparently the name Bohm has an umlaut over the "o". So, the pun only works if pronounced like Inspector Clouseau (Steve Martin version). (-:
