Yes, HAL does play chess in 2001 (beating Frank Poole with little difficulty, though sounding apologetic about it); he is 'infallibly' intelligent- however, there is debate in the storyline as to whether he is alive or not (he is interviewed by the BBC, and the interviewer beforehand says that some people thinks he mimics rather than acts).
Spoiler:
The Monolith thinks he is alive though
