Do different patterns, like coming at the pattern from all sides, taking both the left and the right barrel first, trail riding, lots of long trotting and serpentines...
When he anticipates the turn, you can feel it, right? stop him and be like, "nope! Just kidding" and lope a circle around the inside of the pattern and start over. Also, when trotting the pattern, make your turns super wide, so it's just a biiiig figure 8 between barrels and same when your loping. If he already knows the name of the game, it will keep him from shouldering barrels.
