(1) Endgame # R-1
[Burba,M]
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
