This game in the video is taken from my E-book about endgames with bishops of opposite color.
The book is formatted for electronic readers and can be read on devices of various sizes, from tablets to phones. The free sample includes 3 thoroughly annotated games and the full book comes with dozens of training positions to help develop a good sense for positions with bishops of opposite colour.
This bishop endgame is a good illustration of thinking in schemes. Black had to keep track of the functions of each of his pieces - in the final position the king had to block the pawn 'd', and the bishop - defend the 'h7' pawn. Because they reversed the roles after Anand's mistake, White had an option of breaking through to the 'd' pawn and winning a piece.
An unexamined life is not worth living.
