Number 379 is from an actual game (Rashid Gibiatovich Nezhmetdinov vs Vladimir D Sergievsky, 1966). The game ends with 20. Rxf6 gxf6 1-0 (see below).
CT-ART has the position continue with 21. Ne4 Qa7 22. Nf6#. What threw me off was I was expected 21 ... Qe7, not Qa7. Even if Qe7, white will still go on to win, but it's better than letting the game go with Qa7.
For what it's worth, I've seen lots of problems in CT-ART where mate could have at least been avoided, but it is not. It's not big deal, but since I put a little research time into this one, I decided to blog it. Go read the kibitzes on chessgames.com for this game ... they proved to analyze better than CT-ART.
