  OlimpBase: Heheh, yes, there WAS a Short-Moraza games played in Dubai, 1986, of which the moves are correctly displayed by Yet one Short was of course not famous Niget but Philip, an obscure Irish player. BTW I cannot find some major Dubai 1986 games like Georgiev-Suba, Campora-Seirawan, Ftacnik-Popovic, Spraggett-Torre, Nogueiras-Kindermann. If you happen to know the moves please let me know.

  OlimpBase: BTW Nigel Short-Moraza, England-Puerto Rico, round 1 game was forfeited by the Puertorican as an act of protest against late pairing corrections that threw them into merciless English hands after they had felt a nice, fuzzy feel of being paired vs Zimbabwe.
Jun-07-14  Bycotron: Hail! Warriors of chess! I find this endgame interesting and I'm going to take a swing at analyzing it. I don't have a computer to aid me and I'm not particularly strong so if anyone can find any corrections or improvements, please do!

I'm going to start with the position after 55...Kc2

Why would white play Rxb2 here? White should let black force the issue on the queenside and he should keep in mind that taking the pawn after it goes to b1 will pull the black King farther from white's pawns.

So white should play 56.h4! with the idea of promoting his g-pawn as quickly as possible (the immediate 56.g6?? simply loses the pawn to 56...b1=Q followed by ...Ra6)

56...b1=Q 57.Rxb1 Kxb1 and now 58.g6! promoting the g-pawn as fast as possible!

Black cannot now win the pawn as before. 58...Ra6 59.h5 Ra5 60.f4! and if 60...Rxh5 61.g7! 1-0

Other tries for black on move 58 don't seem to hold the game so I believe white is winning in my suggested line. Can anybody correct me?

All decent-looking moves for Black seem to be crushed easily, Kc2, Ra5, Ra8 all simply lose. It is a shame white lost this well-played game when it seems to me he should have easily won.

This is a theoretical draw.

After 57.h4 Kc3 White made a mistake by playing 58.Kh3? and Black is winning.

He should have drawn with 58.Kg3, 58.Kf3, 58.h5 or 58.f4 e.g.

58.h5 Kd4 59.h6 Ke5 60.f4+ Kf5 (60...Kxf4 61.h7) 61.Kf2! Ra8 62.Kg3 Kg6 63.Kh3 Kf5 64.Kg3 Kg6 Draw by repetition.

Here, the difference between 58.Kh3? (Black wins) and 58.Kg3 (Draw) is that after 58.Kg3 Kd4+ White has 59.Kf4!

Sep-21-14  RandomVisitor: Worth further attention are: 53.Rb6, 41.Kf3, 37.d8Q, 34.Ng4 and 29.Qxc4.
Sep-21-14  RandomVisitor: For example, after 53.Rb6!

Rybka 4.1 x64:

+M38 d=27 53...Kd3 54.g5 Kc3 55.g6 b2 56.Rxb2 Ra6 57.Rb5 Rxg6+ 58.Kf3

Sep-26-14  Bycotron: In my previous post, I wrote:

"I'm going to start with the position after 55...Kc2

Why would white play Rxb2 here?"

Upon returning to the position, I saw the answer in a flash of course. :) Black threatens to win the game with 56...Rb3, interfering with the white Rook's control of the promotion square on b1.

Thus white is forced to play 56. Rxb2 and accept a draw as previously shown by other kibitzers.

Sep-26-14  Bycotron: I am now looking at the position after 52...Ke2??. At first blush, it looks very foolish for black to abandon his b pawn with the King and intuitively it feels like a mistake for white to chase the King back to the pawn's aid with 53. Re6+?. Can anyone confirm or disprove my suspicions?

I suggest the following...

53. g5! and how can black save the game?

53... b2 loses simply
54. Rb6 Ra2 (note the King cannot defend the pawn anymore so the Rook must) 55. g6 Kd1
56. g7 Ka8
57. Rxb2 1-0

53... Ra7
54. Rb6 Rg7 (again note the black King's useless presence on e2!) 55. h4 and the b pawn will fall e.g.
55... Rf7
56. Rxb3 Rxf2+
57. Kg3 1-0

This is a tragically misplayed endgame by White! I'm sure he learned a lot from it, though.
