tip: When first learning the game, use the tutorials provided in the manual. But pay attention to what you are doing since the scenarios provided don't always follow the script in the tutorial to the letter.

tip: The computer AI is a decent opponent and will vary its tactics from game to game. It can be fooled, however. Try sending a weaker unit to probe a far-off part of the enemy line. In most cases, the AI will react to the perceived threat and move unneeded units toward that part of the map.

tip: One of the components of the victory conditions is control of certain hexes. If you are desperate or devious enough, send lone cavalry units off to occupy those victory hexes for a turn. It's a cheap (and time-honored) way to win, but all is not
fair in war.
