Endgame Lab - Rooks - Lucena's Position
Salvio, 1634 - White to move and win General Setup: Defender's King is pushed out of the pawn's way and cannot access the Queening square. Attacker's king is in front of his pawn, on the queening square. The basic winning technique here is to "Build a Bridge" - interpose the attacking Rook between the checking Rook and attacker's King. Once that is achieved, the position is lost as the exchange of Rooks results in a won K+P vs. K endgame. The general technique is as follows: 1) Superior side advances pawn to the 7th rank. 2) Superior side uses Rook to push defender's King out of the way. 3) Advance Attacker's Rook to the 4th Rank in preparation for 'Building a Bridge'. 4) Move attacker's King out of the way of his pawn. 5) Advance attacker's King toward defender's checking Rook. 6) Interpose attacker's Rook on the 4th rank to block checks - 'Building a Bridge'. 1.Rd1+ Kc7 "Superior side uses Rook to push defende...
