Are you serious? Everything he has already read is WAAAAY above the level of that book. That would be a total waste of time. While it is a good book, anyone rated about 1000 or above will not get much out of it.

The best book I have seen on calculation is “The Inner Game of Chess” by Soltis. It’s even better if you can study Soltis’s “How to Choose a Chess Move” first, but that book is out of print and used copies are somewhat pricey. I did Inner Game first and learned a lot more from it than from Kotov.
