Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It can be described as the ability to perceive or infer information and to retain it as knowledge to be applied to adaptive behaviors within an environment or context.
(from Wikipedia)
Intelligence is multifactoral. Being good at chess was one aspect of intelligence in the complexity of Daniel's life, and in anyone's life.
