I actually found playing against a computer to be extremely frustrating from the perspective of trying to learn & better my game. Computers simply do not play chess in a style that's comparable to human chess players. Human chess players that are far better than I am and will win 90% of games against me still occasionally miss tactics or fail to evaluate a position properly. That's absolutely not true of a computer by default. Playing long games was fantastic for improving my chess. Most chess teachers also advocate long games as the best way to improve your game. The two ways I found to play long games, were to go to my local chess club and sign up for tournaments and to play in leagues on ICC, the internet chess club.
