"Dr. Tarrasch is a thinker, fond of deep and complex speculation. He will accept the efficacy and usefulness of a move if at the same time he considers it beautiful and theoretically right. But I accept that sort of beauty only if and when it happens to be useful. He admires an idea for its depth, I admire it for its efficacy. My opponent believes in beauty, I believe in strength. I think that by being strong, a move is beautiful too."
