Black had been under some pressure in the opening and middle game but after careful defence had held the position together. Now the plan is to put pressure on the advanced and marginally weak d5 pawn whilst attempting at the same time to prevent the White queen or rook from penetrating Black's position espcially via h6, c6 or e6.} 27... Qc7 {Using the "Capablanca Method" described by Norman Stephenson in the first game of this article Black had visualised placing the queen on c7, the rook on d6, then the queen on d7 giving the option of playing e6. In this situation White playing Qc6 would generally lose due to Qxc6, due to the pin on the d-file, provided Black has time to withdraw the rook to d8, or the Black king can move to e8, in time to prevent the c6 pawn advancing to c7 and then queening. In addition, even if White exchanges queens, then Black still has the option of e6. If White plays Kc2 to prevent this idea then the Black's king may be able to blockade the d-pawn on d6 and the Black rook become active on c5 or c4.} 28. Re1 {White seeks to prevent Black's plan by activating the rook and attacking Black's backward e7 pawn. However, this plan is a slight error as it relieves the pin in a non-optimum manner. Keeping the game level were both} (28. Rd4 {and}) (28. Kc2 {although White was possibly concerned that the Black queen might become active at some stage by occupying g3 or even h2, or c4 respectively, since of the kings White's is a little more vulnerable.}) 28...

This is a case of "tactical vision" also referred to by Norman in the first game of this article. It had to be seen the White king is simply too active and can advance quickly to attack Black's weak pawns before they can be defended by the Black king and this would require exact calculation of quite a long variation:} 34.

Qd4 {gives some hope despite the loss of a pawn as the Black pieces are somewhat tied up defending d5. If the Black king advnces to relieve the heavy pieces of this burden then White has chances to check with queen or rook to prevent this operation.}) 30...

The two games of this article clearly show that understanding endings is critically important in converting an advantageous position or indeed trying to save a difficult one. In what seems like quite simple positions, with reduced material, the type of endings illustrated in the games also show surprising complexity hence one can only admire all the more the great players of the past such as Capablanca and a handful of others who shone in this stage of the game.} 0-1
