DS is learning chess at school and would like to be able to practise on the computer. One of his friends uses Chess Titans on Windows 7 which DS quite likes, but we don't have Windows 7 and although I can theoretically download Chess Titans it keeps failing.
Thanks NN, that looks quite similar to Chess Titans so DS will be happy with it.
I never knew that DH could play chess until he started teaching DS named openings (Ruy-Lopez so far). I think DH has visions of a future chess champion in the family, I think DS will get bored with it by the end of term.
