Hey, ok so against these style of players keeping the ball tight and low until you can get in a good quality spin is important. I notice quite a few of his serves are coming long and you should try to topspin these to get in the front foot early in the point.
Most of the time when you got your topspin in first you dominated and won the points. And the same for him when he got in the first attack he almost always won. So it’s trying to always look to play the first spin and get on the attack early. Often the ball is long but you still push it back and give him a chance to attack first. It’s about finding the balance of being patient and keeping it tight and then looking to topspin and attack first as much as possible.
