Chess Position Trainer is a state-of-the-art chess software with a focus
on chess opening, training and repertoire management. What a mouthful.
Chess Position Trainer is both free and priceless at the same time.
More simply, Chess Position Trainer is what you use when you want to learn
and train your chess opening repertoire, not fight it.

A "technical preview version" of CPT 4 has been released. It is available here:
