Nice puzzle. I think the lesson here is if your Bishop is directly attacked move it along the same diagonal out of danger. I don't like handcuffing the Queen to the Bishop to defend it. I'd rather use the Queen as an attacker than a defender, otherwise, your opponent can exploit a limited Queen. At the least, the Black Knight was going to check the White King to force an exchange of Knight for Bishop.
