Rook versus Bishop and Pawn. The __ceteris paribus__ condition is here fairly fulfilled, both sides having besides two blocked Pawns each True, the White King has a very advantageous position, but such an advantage can be forced by methodical play as soon as the advantage of Rook versus Bishop and Pawn is conceded. This position represents the final stages of the contest. White has all the initiative, he is the aggressor. He assails the QP twice. It is guarded twice, but by assailing the King White can drive that protection away and thus attain the superiority on Q6.
1 R-R7ch.
K-Q1;
2 K-K6.
Thereafter R-Q7 and RxP. The advantage of the "exchange" is abandoned, since Bishop may now capture Rook, but King recaptures and holds now advantage of position in that it attacks the Black Pawns while the hostile King is inactive and must suffer the destruction of its army of Pawns. Then White wins at his leisure.
