I share with you a series of suite books to use as engine tests or to check books in your private tests. They may not be higher in quality than, for example, the Perfect books or the Balsa suite, but they can be a help and an alternative. I have tried to use games with balanced positions, but it is possible that some variants create an imbalance, depending on the engine used, the selected game times, depth, etc. It is a simple contribution, so I hope you enjoy it.
I want to give special thanks to Oliprog, who have been very kindly using some of these suites. I really appreciate your work.
Kind regards. A.M
