Here is a little this I do and i find it effective for me.. My line is very my like a defenceive line. My flanks are well protected with cavs ( i have at lest 3 - 4 cavs in each army pavs in front, and my sword and anti cavs on each flank as well. As i march I'll stop just enuff for my pavs to fire.. bringing my can unit to distract there pavs or archeres and hoping to bring cav out as my anti cav flanks there cavs. so basicly I try to turn the tables and have them attack me
