Brilliant military manuevers ?

You need to go read Frogbeasteggs guide to MTW (in the guides section)

[Evil_Maniac From Mars]

Here's a classic Ghengis Khan, though it is rather common:
Send cavalry out first, and march infantry a safe distance behind them. Halt infantry out of arrow range. Send light cavalry to harass the flanks, and use heavy cavalry to pound the middle and break through. Send infantry and lights in to sweep up.

"Classic" Otto the Great:
This is how Otto the Great beat the Magyars at Lechfeld, outnumbered over 5:1, and yes, it works MTW. Works best countering cavalry armies with cavalry.
Send two units of cavalry on each flank, slightly ahead of your main line. Rally the rest to the left or right flank around your general, and leave only a token force in the center. As soon as the AI passes your flankers, whom you SHOULD have hidden in trees or moved far enough away, curl the flankers in and pound them. Divide your large force into 3 groups, 2 large and one small. Send the two large ones to hammer the opposing flanks, and send the small one down the center to mop up.

Hope that helps
