How to handle players who always accurately kill the ball a half-inch above the tin from anywhere in the court

Do not allow your hard-hitting opponent the opportunity to make those shots... in other words, you best defence would be a strong offense. Make your opponent hit shots on the run. And it wouldn't hurt you to add to your fitness so that your first step off the T is more explosive. Take pace off your shots while you're at so that your opponent is forced to generate all the power on his own. All this is much easier said than done.

Make sure the ball is not shiny when you play a hard and low hitter. If it is, then the ball will slide quickly when it hits the floor. Wash the ball so the surface remains grippy. This way the ball will slow down and bounce up from a hard / low hit.

One advice I read from the latest Squashmagazine from Chris Walker is to play high to his backhand. This is because it is very difficult to generate power on the high backhand side.

While taking the pace off the shots may be effective some of the time, it would also give your opponent time to wind up and take aim. The key is keeping the ball tight to the walls. I would also recommend trying to volley more, keeping your opponent consistantly under pressure and on the back foot - he would be a lot less accurate when he his rushed. Use a variety of pace so your opponent finds it difficult to keep rythym and timing. As you said, this is a whole lot easier said than done.

pin him to the back of the wall more during the starting stages. play tight shots to the wall. play a more close game. resist the temptation to attack early on, unless you are very sure to win that rally. then, in the middle stages, i would recommend more drop and lob shots. the goal is to frustrate your opponent, not letting him playing his favourite shots.

I agree with all the previous posters. If you don't give your opponent the opportunity to put the ball six inches above the tin, he'll have a harder time hitting it. If he does attempt the shot (i.e. hitting offensive shots in a defensive or neutral situation), he will be more likely to hit the ball six inches below the tin. If he IS able to hit the shot from anywhere, he shouldn't be playing you. He should be playing more challenging players.

Have you paid attention to which shots he can easily kill. I suspect they are medium speed in the middle of the court. Some things you could try 1) bring him to the front with boasts or drops 2) keep him in the way back behind the service box 3) hit the ball harder even if it is a bit looser 4) try lobing or at least keeping the ball higher and softer 5) hit your own low and hard balls.

Basically, vary the pace of the ball and keep the ball in the back, up high, or the striking point below the tin.

If this is his favorite shot then you must be ready to move forward on every ball. Get to the T, stay on the balls of your feet, knees slightly bent, and ready to sprint like a maniac to the front. It is much easier to take a forward leaning motion and reverse it to the back corners, than it is to take a backward leaning motion and reverse it to the front corners.

Of course this is all theory. I have the same problem with people who drop from anywhere on the court. Unconvientional squash players are very frustrating.
