A few days ago I posted here a proof game, but it was in reply to another post and I think many people missed it (nobody solved it!). So I post it here again... sorry if you already saw it in the other post. If you didn't see it there, don't do so now, since in that post there is a hint to the solution.

That doesn't mean others can't solve it too🙂
Edit: Just the fact that Labelle is a co-author is always a sign of trouble - he's more a programmer than a composer. His co-authorship is a sure sign that this is the type of problem that humans can't get sound without computer help.

1. Faybish
2. Wicklund
3. Labelle & Leroux
All 3 teams composed very similar PGs in response to a challenge (After the problem is solved I'll say what the challenge was), so it was decided to choose one version and publish it under the 4 names together. Which means, the problem was composed independently by two 1-man teams which did not include Labelle... so maybe the situation isn't so bad.
If I remember correctly, this problem indeed is not C+ - computers have problems with the large number of captures.
