Innocentius, I agree that it would be overly-simplistic to stamp all westerners as poor tacticians, but while I am certain that they all had a good understanding of battlefield movements, the history of the Crusades is full of examples of Heavy Knights craging recklessly into the enemy, falling into ambushes and suffering defeat.
For example, after the fall of Constantinople, the newly proclaimed Latin Empire decided that it felt powerful enough to immediately go in war with its neighbor Bulgaria, despite the fact that nominally Bulgaria was Catholic and the Pope warned the Latins to remain in piece. When the armies met in front of the walls of Adrianople, the Bulgarian Tzar deployed his infantry in the swamps and forests arounf the Maritza river, and sent his auxilliary Cuman cavalry to harass the Crusaders. Apparently all the knights decided to try to charge the Cumans without waiting for any of their other troops, and the whole Latin cavalry simply took off after the Cumans without even holding its formation, falling into the ambush in the swamps and forests, which all resulted in a disastrous defeat, in which the Emperor Baldwin himself was captured.
Several years later, there was another battle between the Bulgarians and the Latins in front of Plovdiv. The Bulgarians pulled the same trick and the Latins fell for it again, which comes to show that Western Knights who faced eastern armies simply showed a complete disregard for tactical movement and relied heavily on their devastating charges.
To further illustrate the point, the lack of discipline of such Knights brought about the catastrophic losses for the Christians against the Ottomans in battles of Nicopolis and Varna. Apparently, the Western Knights chose to ignore lessons learned in the past.
