White lost because he failed to remember the right continuation and had to think up the moves himself

White has no positional equivalent for the centralized pawn.

When you don't know what to do, wait for your opponent to get an idea; it is sure to be bad.

Every move creates a weakness.

A thorough understanding of the typical mating continuations makes the most complicated sacrificial combinations leading up to them not only not difficult, but almost a matter of course

Always put the rook behind the pawn.... Except when it is incorrect to do so.

Chess, like love, like music, has the power to make men happy.
