All the advice above sounds pretty solid. The thing with anti-spin that is worth understanding is that, you need to practice against it enough to get used to what will come back and to get used to watching the which rubber your anti-spin opponent is using. A lot of good anti-spin players also flip (twiddle) their blade face. If you stop paying attention and they flip from one side to the other, you could miss seeing what spin is coming at you. As you get used to anti-spin, a nice way of thinking about it is this: if they use their anti-spin side, you are controlling the spin that will come at you. So the actual question is: how do you use this to your advantage.
Well, if you like hitting against topspin, you should give underspin. If you like hitting or, really, looping, against underspin you should give topspin. If you want the ball to come back slow, server short and slow. If you want the ball to come back faster serve faster.
Here are some things that I like to do.
1) I like to keep the ball in play, being patient and waiting for a ball I can put away and end the point. To do this, you have to be comfortable letting the rally go longer while playing against an anti-spin player. That means you have to have played a decent amount against anti-spin. I like control looping, so that, the shots coming back to me from the anti-spin have a consistent amount of underspin. Then I just keep looping the underspin knowing that I will eventually get something I can really rip and end the point.
2) I have realized, the way I play, I do not like facing short, low, heavy topspin, so I have no intention of giving short serves that have heavy underspin to an anti-spin player. But if someone gives me a short ball that is light underspin, I love attacking that. So, if I want light underspin, I give short light topspin serves that are disguised to look like underspin. Often that also means I can get my anti-spin opponent to give me something high and slow if I disguise the serve well.
3) I might not like topspin that is short and low, but I love topspin that is long regardless of whether it is slow or fast. So: fast, long underspin serves are going to come back as topspin and if it is a good fast serve, it will be hard for your anti-spin opponent to keep those returns short and low. So that is another way of getting a good attack. However, you have to be careful with this, because, if you give a player who has anti-spin any underspin ball, when they hit it back it is a topspin, and they do not have to worry too much about hitting it into the net, so, a good anti-spin player will probably just attack that if they realize what it is. If it has a lot of underspin it could come back with heavy topspin (a loop). So you have to use the element of surprise with this one and have some long fast dead ball serves and long fast topspin serves that all look similar so they are not exactly sure what spin is coming at them. If you served it, you should know what spin you put on your serves so you should know what spin is coming to you.
4) Fast dead serves might not give a good anti-spin player much trouble in terms of returning them. However, when a dead ball serve comes back off of anti-spin, it is not going to have much spin. If you know how to attack dead balls, this could give you an easy set up to attack and end the point.
For me, once I am past the serve and receive part, and I am in the rally, I like using control loops and trying to keep my opponent using his anti-spin side. If I do that, the spin that is coming back to me is fairly consistent so eventually I will get something to attack and put away. The advantage when you play an anti-spin player is that, if they use their anti-spin side, you are determining the spin they put on the ball. You just have to hit with anti-spin players enough to get used to this. When you do, it is also worth experimenting with sidespin serves because you need to know what will come back at you if you use a sidespin serve. And just like when you hit topspin or underspin at anti-spin what comes back at you is counterintuitive. So if you have not seen it enough to get used to it, it could cause you some problems.
When you hit topspin, what comes back is underspin. When you hit underspin what comes back is topspin. But when you hit sidespin at anti-spin, what comes back is THE SAME sidespin. So, if you do a regular pendulum serve, and you give side spin that causes the ball to curve towards the backhand of your opponent (right handed player), when the ball comes back, it will curve towards your backhand also (right handed player). If you are good at attacking serves that have a lot of sidespin without top or underspin, it can be a good tactic also as long as you have seen how much sidespin your serves are going to come back with, and as long as you have seen this enough times to be used to it, before you try this in a match. But the ball is going to curve on you if you have a lot of sidespin. An advantage to this, a sidespin ball that does not have almost any topspin or underspin is easy to attack provided you know how to deal with the sidespin that is coming at you. If you do not, stay away from heavy sidespin until you do.
It is absolutely true that, if you mix up the spins and keep giving variations, you can get an anti-spin player to mess up. It is a good tactic. The reason I use this for serve and receive but not if my opponent gets past my third ball attack, is, I have found I am not good enough to deal with all those variations of spin that come back to me.
So, sometimes I mess myself up before I get to mess my opponent up.
So for me, I know, once I am deeper into the rally, if I can keep moving my opponent around and keep the spin that is coming back to me as consistent as possible, I will get balls to put away and end the point.
