White does not have the coordination to create any significant counterplay, while the transformation 1.Rxa7 Rxg3 2.Rxh7 Rg2+ 3.Kd1 (3.Kd3?? c4#) 3...Rxa2 leads to a lost position similar to Diagram #79. } 1.f5 (1.Rxa7 Rxg3 2.Rxh7 Rg2+ 3.Kd1 (3.Kd3?? c4#) 3...Rxa2 $19) 1...c4 2.Rf3 { White positions his rook behind his own passed pawn, but there is no time for its advance. Black not only has a few extra tempi, but his advancing pawns create threats against White's king. } c3+ 3.Kc2 Kc4 4.Rf4 { Otherwise 4...d3#. } Rg2+ 5.Kc1 Rxa2 { These two examples showed clear positions in which realizing the positional advantage was relatively easy. As we already know, in situations of no material advantage, with a positional advantage not so clear, the method of realization involves improving the favorable strategic qualities for our position, without neglecting the whole tactical arsenal. } 0-1
