well. But additionally there is another defense available:[#]} 71. Kg5 $2 {

{4.4 Same colored bishop ending general case Basically the attacker has two
different strategies how to handle the pawns. They can be put on the same
color of the bishops to restrict the defending bishop or they can be put on
the other color to control more squares, attack the defending pawns and invade
with the king through the holes. The second strategy is also called
Capablanca's rule and we start with it.  A) Capablanca's rule Two pawn
weaknesses can already be fatal, if the attacking king can reach both and no
counterplay is possible:[#]} 83... Bf8 $2 {This is too passive and allows

{5.3 General case The drawish tendency of pure opposite colored bishop endings
is extremely large as both bishops live in different worlds. The main theme is
constructing and breaking a fortress. A) The nature of fortresses There are
basically two different types of fortresses: 1) The defending king blocks the
passed pawn and the bishop defends the other wing 2) The bishop has the passed
pawns under control and the defending king follows the attacking king and
prevents its invasion For the defending bishop the principle of one diagonal
and taking aim at pawns are very important. Often positional considerations
are more important than material:[#]} 63... b4 $5 {The easiest defense as now
the bishop can control the queenside.} (63... Ke6 64. Bb4 (64. Kb6 b4 65. Kxa6

{General Case Again the nature of the fight depends, which minor piece is
playing for a win. A) The bishop has the advantage The bishop usually like to
have dynamic options, fluid pawn structures to restrict the knight also with
the pawns and without weak squares or outpost for the knight, play on both
wings and the knight should have no concrete role and might even be dominated.
Typical weapons are dominating the knight, invading with the king, creating
dangerous passed pawns, zugzwang and fortress breakers. We will look at them
in more detail. A1) Geometrical domination motifs A we have already seen in
the chapter 1 the knight has a special geometry. Certain typical motifs occur
often, when the bishop tries to dominate it:[#]The bishop corralls the knight
at the edge, a typical domination distance. But to win still care is required
as a mutual zugzwang is nearby:} 51. Kd4 $2 {White rushs.} ({The mined square
