The Sargon series were the connoisseur's chess games at the time. This edition includes variable move times, ranging from 5 seconds to infinity. Moves can be undone and you can swap sides during the game. The search feature displays its calculations as you play, which can be useful to learn from. Special tactical situations, opening move sequences and checkmate practices can be loaded in for learning purposes.
The first four games were written by the same couple - husband and wife! Part 5 was released by Activision but lacked that certain "originality" that was in the first three. Sargon 4 was a great game but was released by a really bad company called Spinnaker - they did nothing to promote this game and that was a REAL SHAME. The gameplay was good, but the manual and box were terrible.
