Lucky is a very speedy horse, and he loves to go as fast as possible. However, he is also very sensitive. If I squeeze lightly or cluck, he'll move up a gait. If I do half-halts, he'll move down a gait. If I pull back, he'll slow to a walk or stop. If I squeeze lightly and do half-halts, he gets confused. It seems like to him, there is no fast or slow for each gait. There is just walk, trot, canter, and gallop, and each has only one speed.
I know he has been trained properly, because I've seen other people ride him before. So, how do I control him properly???
