Endgame # R-1

(1) Endgame # R-1

The Lucena Position. 1...Rh2 2.Rf4 White will win by a technique called 'building a bridge'. The bridge is the only way to win in the case of a knight pawn. For bishop and center pawns the superior side can win by the bridge or by another technique, which I will call 'lifting the rook' (see R-2). The lift is the only way to win for rook pawns. 2...Rh1 3.Re4+ Kd7 [ 3...Kf6 4.Kf8+- ] 4.Kf7 Rf1+ 5.Kg6 Rg1+ 6.Kf6 Rf1+ [ 6...Rg2 7.Re5 Rg1 8.Rg5+- ; 6...Kd6 7.Rd4+ Kc6 ( 7...Kc7 8.Rd5 Rg2 9.Rg5+- ) 8.Rd8+- ] 7.Kg5 Rg1+ 8.Rg4+- 1-0
