I spent thousands of hours in my teens studying chess and playing in USCF tournaments. That was some time ago. Now I occasionally play chess with the computer for fun. I beat it sometimes, but those occasional wins come because of a strategic plan often involving a sacrifice. The program is just too strong at tactics to win by means of a short-term series of moves.
Try Sigma Chess (sigmachess.com) for a more robust program. You can set easy levels where the computer will make tactical mistakes you can take advantage of ---- if you are careful. You can also set the levels very high. Be careful.
