Welcome to this active site. Each week I am
going to present to you an endgame position for you to solve or to
workout the best continuation. Computer analysis will also be
considered. Some of these positions will come from actual historical
games. Others will be composed endgame studies, but all the solutions
will be relevant to the practical game. The new position will occur
each SUNDAY and
I will always be pleased to receive
POSITIVE feedback about the positions and
the analysis and I will try to acknowledge these where
relevant.
Thanks to Antonio
Senatore, Henryk Kalafut, Jon Palmer, Gerald O'Reilly, Valdir Uchoa
Jr, Yuriy Steschenko and Rainer Staudte.

Candidate. Many times champion of Iceland. 1st equal with
Korchnoi at Hastings 1955/56. In the Portoroz interzonal tournament
of 1958 he came 5th= with Bobby Fischer, thus qualifying for the
Candidates Tournament of 1959. Former FIDE President. In 1982

Olafsson vs Tal
Portoroz, 1958
White to play and WIN
FORSYTH NOTATION

This ending played in the final round of the tournament was
very tense. Tal had secured his place in the 1959 candidates by
beating Panno brilliantly in the previous round. He only wanted a
draw to come 1st in the tournament but Olafsson found himself in a
good position in this Rook and pawn ending so he wasn't interested in
sharing the point. During the adjournament Tal and his second Koblents worked out a plan to create a
situation in which Olafsson might make a mistake and thus increase
Tal's chances of saving the ending. Their plan worked and so Tal came
1st, but Olafsson was not too disappointed with the result as he only
needed a draw to secure his place in the Candidates. We start with
the moves played in this difficult ending but from move.5.d7!! we follow the proposed winning line.
1.Kd6! ...
White threatens mate and the King is ready to
support the passed pawn to it's queening square.
1... Kf8
This looks crazy taking away the King from the
passed pawn but Tal complicates knowing that the ending is
technically lost for him.
1...f6 2.Ke6 Re3+
3.Kxf6 Rxf3+ 4.Kxg5 Ra3 5.Kf6 a4 6.g5 Rf3+ 7.Kg7 a3 8.g6 Rh3 9.Kg8

3.d6 Kg7
4.Ke8! ...
Threatening Rxf7+ ,
4.Kc8? Rc3+ 5.Kd8 a3 =;
4... Rxf3
5.d7!! ...
This leads to a clear win. In
the game he played 5.Rxa4?!
White is still winning but it is more
difficult. Play continued: 5...Re3+ 6.Kd8 f5 and Olafsson went wrong
with 7.gxf5? (Instead 7Ra5! was White's last
shot to win: 7...Kf6 8.Rxf5+ Ke6 9.Ke8! Kxd6+ 10.Kf7! Re4 11.Rxg5
Rf4+ 12.Kg7 Ke7 13.Rg6 Rf7+ 14.Kh6 Kf8 15.Ra6 or 15.g5 win according
to EGTB's ) The game continued: 7... Kf6 8.Ra6 (8.d7 Kxf5 9.Rd4 Ra3!
10.Kc7 Ra8! 11.Ra4 Rg8=) 8...Kxf5 9.Kc7 g4 10.d7 Re7 11.Kd6 Rxd7+
12.Kxd7 g3 13.Kd6 g2 14.Ra1 Ke4 game drawn;
5... Re3+
Forcing the enemy King to block his own
pawn.

Covers the queening square and thus secures the
promotion of the d-pawn.
7.Kc8 Rc3+ 8.Rc7 Rxc7+
9.Kxc7 a2=;
7... f5!
Black counter-attacks by
creating a passed g-pawn on the kingside which will be supported by
the King. From what follows we see that this plan only just
fails.
7... Kf6 8.Kc7 Rc3+ 9.Kb6 Rd3 10.d8Q+ Rxd8 11.Rxd8 Ke5
12.Ra8 Kf4 13.Rxa3 Kxg4 14.Kc5 f5 15.Kd5 Kf4 16.Ra4+ Kg3 17.Ke5 f4

14.Ke3 a2 15.Ra8 Kf5 16.Rxa2+-;
13.Rd2! ...
The advanced passed pawns must be held on the 3rd
rank.
13... Kf6
The King travels forward to support the advanced
g-pawn.
14.Kd4 Kf5
15.Ke3 Kg4
16.Ke2 g2
17.Kf2 Kh3
18.Kg1 WINS
It is a close finish. The White King gets back just
in time. A very instructive ending.
