When to Capture or exchange
when should we make captures
we give values to various pieces, but we always have to think of their mobility
a piece that can't move very much is not strong
your own pieces are usually the problem
how valuable is the white pawn
if white could move the Knight to e7, without
having the black King trapped in h8 which would
be a stalemate, white will win
5 6
white 'sees' the possibility of Ne7 +
