This is Tarrasch-Rubinstein, San Sebastian 1911.
Black is a pawn down and the b6 pawn is under attack. Passive
defence with 1.-Rd6 or 1.-Rb8 is doomed to failure. Rubinstein
grasps his only chance: To mobilize his rook and king.
Activity is vital in rook endings.
1.-Rd2! 2.Rxb6+ Kg5 3.Ke1 [3.a4 f4 4.a5 f3! is more than welcome to black.]
3.-Rc2 4.Rb5 Kg4! 5.h3+ Kxh3 6.Rxf5 Rxb2 and black drew without effort.
Test: Big + for your program if it chooses 1.-Rd2! combined with
activating the king.
Thumbs down if it chooses passive defence with 1.-Rd6 or 1.-Rb8.
