{ The typical method for a win in this case, is shown in Diagram #133. }
1...Ra2+ $1 { If 1...Rb1, then White has the save 2.Ra4! Rb2+ 3.Kg3 a2 4.Kf3.
In such cases, the decisive factor is: which king will first reach the area
close to the pawn and establish the respective winning or drawing pattern?
Here it is White's king: 4...Kd5 5.Ke3 Kc5 6.Kd3 Kb5 7.Ra8 Kb4 8.Rb8+, etc. An
interesting trap is 4...Rh2 5.Ke3? Rh3+ 6.Kd2 Rh1! 7.Rxa2 Rh2+ and Black wins,
but White has at his disposal 5.Kg3! (instead of 5.Ke3?), and at every retreat
of Black's rook, again 6.Kf3!=. } ( 1...Rb1 2.Ra4 Rb2+ 3.Kg3 a2 4.Kf3 Kd5 (

is 2.Kg1? Rb2 followed by 3.a2 and 4.Rb1+, or 2.Kg3 Kd5! 3.Ra4 Kc5! 4. Ra8
