Larsen was known as a deep thinking and highly imaginative player, more willing to try unorthodox ideas and to take more risks than most of his peers. This aspect of his play could even manifest itself in his choice of openings. "He is a firm believer in the value of surprise. Consequently, he often resorts to dubious variations in various openings. He also likes to complicate positions even though it may involve considerable risk. He has a great deal of confidence in his game and fears no one. His unique style has proven extremely effective against relatively weak opponents but has not been too successful against top-notchers."
