In my computer Hiarcs 8, Fritz 7, Crafty 17.14 fail to see 62...Rc1. Now let us examine the position from an human point of view. First, I have to state that after 62...Rc1 63.Rxa2 Rc2+ the pawn-ending is too easy for me and -I assume- for any strong player who with enough experience. From a practical point of view 63.Rxa2?? is a blunder: why enter a lost simple endgame? In practice, a human player has to try something like 63.Ra3+ Rc3 64.Ra8 Telmo
