GatoNegro> AND... after Nd1 it not possible to play Rb1-e1 because the first rank is blocked by the knight on d1! please!!!!!
What are you talking about? This is getting silly. Re1 means "Move the rook on h1 to e1". It does not mean take the other rook and magically hop it there. I'm going to go offline to cook some Spaghetti... good luck. :)
Use the other rook... I thought you wanted to leave that b rook there anyway to guard b5.
