Apr-27-06  Autoreparaturwerkbau: Interesting pawn structure after 27th move. Looks like double stairs. :)
Jan-30-07  GrandPatzerSCL: I cannot believe that ANYONE won this game. The pawns lock incredibly that it seems as though BLACK should have forced a draw. It's good to see how WHITE weakens the h5 pawn, forcing BLACK to surrender it so as not to allow it to tie up his pieces. This gives WHITE the decisive initiative with the passed pawn such that he could have left that rook en prise.

  al wazir: Black cut his own throat. White might have blasted the h-file open, but black made it easier for him by unblocking the position with 23...h6. Then, instead of playing 37...Rh8, he began operations on the long diagonal, allowing white to invade on the kingside.
Jan-30-07  hellstrafer: I don't think it was intended for the pun but "harika" means brilliant in Turkish and Arabic.
Jan-30-07  laskereshevsky: <Autoreparaturwerkbau: Interesting pawn structure after 27th move. Looks like double stairs. :)>....

YEAH,Just one step.....its a pity that the black a5 pawn isnt in a3....

Jan-30-07  Manequinho: Was 43.Qh5 the "eureka" move?
Jan-30-07  kevin86: <autoreparaturwerkbau> I noticed that too,with both players having two sets of interlocking pawn chains.

It wasn't much of a sac as the rook was quickly recaptured-but the attack had to start somewhere!

Strange,in this interlocked pawn position,the knights have no role at all!

Jan-30-07  GeauxCool: Here's a game where a single pawn took out one set of Rahman's stairs.

  perfidious: <saffuna>, you're just jealous: his coruscating brilliance and smashing ?clat win the palm every time.

  saffuna: Well, <perf>, I am off to such a late start.
Aug-17-23  Brenin: 43 Qh5 abandons the R on c2, but after 43 ... Qxc2 44 Qh4+ Ke8 45 Qh8+ Ke7 46 Qxa8 regains the material, and his g-pawn beats Black's b-pawn in the promotion race, since White can gain tempi by checking Black's K whereas White's K is protected by those finally useful Ns.
Aug-17-23  mel gibson: I saw that within 20 seconds.

score for White +36.53 depth 39.

Aug-17-23  agb2002: White has a knight for a bishop.

Black threatens 43... Ra2 44.Rd2 Qxd1 followed by an attack against the c- and g-pawns.

The weak dark squares around the black king and the advanced g-pawn suggest 43.Qh5:

A) 43... Qxc2 44.Qh4+ Ke(f)8 45.Qh8+ Ke7 46.Qxa8 must be winning. For example, 46... b3 47.g7 b2 48.g8=Q b1= Q 49.Qa(g)f8#. Or 46... Qc3 47.Qxb7 b3 48.Nxf5+ Kf6 49.Qxd7 b2 50.Qe6(f7)#.

B) 43... Rg8 44.Qh7+ wins (44... Kf8 45.Qf7#).

C) 43... Rh8 44.Qxh8 Qxc2 45.g7 wins.

D) 43... Rf8 44.Qh4+ Ke8 (44... Rf6 45.Nh5 Qxc2 46.Qxf6+ Ke8 47.Ng7#) 45.Rg2 must be winning. For example, 45... Qc3 46.Nh5 b3 47.g7 Rg8 48.Nf6+ Kf7 49.Nxg8 Kxg8 50.Qh8+ Kf7 51.Qf8#.

E) 43... Be8 44.Qh7+ Kd8 (44... Kf8 45.g7+ wins) 45.Qxb7 wins decisive material.

Aug-17-23  Brenin: Black missed a draw with 42 ... Ra2, e.g.

(a) 43 Qh5 Qxc2 44 Qh4+ Ke8 45 Qh8+ Ke7 and the threat of Qg2 mate forces White to keep checking.

(b) 43 g7 Rxc2 44 g8=Q Rg2+ 45 Kxg2 Qxd1 46 Qg5+ Kf7 47 Nxf5 Qf3+ 48 Kg1 Bxf5 49 Qxf5+ Ke8 50 Qc8+ Nd8 and both Ks are too exposed to Q checks to make progress.

(c) 43 Rd2 Qxd1 44 Rxd1 Kf6 and Black's b-pawn will win the game.
