This next game, for me, emphasizes the importance of A) pinning your opponent's pieces whenever it is both feasible and does not lose tempo; B) the power of a Queen sacrifice at a crucial moment; and C) the importance of not overloading a defending piece by giving it too much to do. Supposedly this is called Rubinstein's Immortal Game because he sacrifices material from the end of the set-up, all the way to the finish, and is a powerful demonstration of his brilliant positional play. I just think it's beautiful.
