C) Exchanging into a Pawn
Ending
Exchanging the last piece should not be a decision
taken lightly. In the other phases of the
game, and even in other types of endgame, in
view of the complexity of the positions you
sometimes have to be content with general
evaluations such as 'White has the initiative',
'Black has compensation' or 'the position is unclear'.
In pawn endings, however, the only evaluations
are 'win', 'loss' or 'draw'. Owing to the
reduced material, mistakes in pawn ending can
no longer be corrected and therefore you must
7h4?
This is too wasteful of tempo moves. 7 @g4
g6 8 b4 and White wins as in the game.
