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, Rainer Staudte, Henryk Kalafut, Gerard O'Reilly, Jon Palmer, Valdir Uchoa Jr and Yuriy Steschenko.

White to play and DRAW

FORSYTH NOTATION :3r4/8/3pR3/K7/7p/p2N4/4P3/3k4 w - - 0 1:

White has a material advantage of a Knight for two pawns. But the Black a- and h-pawns are very dangerous for they are not far from promotion. The White Rook plays a wonderful role in defending against the passed pawns on both flanks. The a-pawn particularly needs to be dealt with straightaway so White's first move is not difficult to find. It is important to remember that White is fighting for a draw here.

1.Nb4 Ra8+

1...Rh8? 2.Rxd6! heading for a theoretical draw with Knight against Rook (2.Ka4? h3 3.Kxa3 h2 4.Nd3 Kc2 5.Nf2 Rf8 6.Nf1 Rf1 7.Ng3 Rg1 8.Rh6 Rxg3 9.Kb4 Rg2 10.e4 Kd3 11.Rh4 Rg1 12.Rxh2 Rb1+ 13.Ka4 Kxe4 Wins) 2...

5.Rg6! ...

In order to draw the Rook needs to get to the 1st rank to fulfill its defensive role. If the a-pawn now promotes, the new Queen will be won by a Rook skewer.

5.Rxd6+? Kc2 6.Ra6 Kb1! (6...Kb2?? 7.e4 a1Q 8.Rxa1 Kxa1 9.e5 h310.e6 h2 11.e7 h1Q 12.e8Q =) 7.e4 h3 8.Rf6 a1Q 9.Rf1+ Ka2 10.Rf2+ Qb2+Wins;

5... Kc2

6.Rg1 Kb2

White now has a very subtle defensive plan where Black although having a new Queen is forced to repeat moves or else enter into a lost ending. An important feature of this plan is to block the diagonals a7-g1 or a8-h1, depending on which file the defending Rook is on, with the e-pawn, so that the new Queen cannot attack it.

7.Rg2! ...

The apparently obvious 7.e3? loses to: 7...h3! forcing the Rook to a vulnerable square. (7...a1Q?? 8.Rg2+ =) 8.Rh1 a1Q 9.Rh2+ Kb1 10.Kb3 Qa8! Wins;

7... a1Q

7...h3 8.Rh2 a1Q 9.e4+! Kc1 10.Rh1+ Kb2 11.Rh2+ with a draw.

8.e3+! ...

This important pawn move blocks the critical g1-a7 diagonal.

Pushing the pawn two squares loses: 8.e4+?? Kb1 9.Kb3 (9.Rg1+Ka2 10.Rg2+ Qb2+ winning) 9...Qd4 wins;

8... Kc1

8...Kb1?? loses to 9.Kb3 !!

9.Rg1+ Kb2

10.Rg2+ DRAW

A wonderful study showing brilliant defensive play by White.
