When connected pawns are not blocked, of crucial importance will be how far they have advanced, on which files they are located, as well as the relative position of bishop with respect to pawns. The fundamental strategic rules that must be observed by both the stronger and weaker side will be explained in the following two examples. The first rule goes as follows: The stronger side’s bishop must be placed in such a way so as to control the two nearest squares in front of the connected pawns. Otherwise, the weaker side will secure a draw by opposing the advance of the pawns by a counter-attack or by blocking them. The proof for this assertion will be provided by the analysis of the following position. White to play cannot win since his bishop is on the “wrong” diagonal and will in the process of transferring the bishop onto the “correct” a2-g8 diagonal lose momentarily control of the e6-square, which will give Black the opportunity to save the game in a study-like way.
