- 26 May '08 11:10A 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.

I've been working on it off and on, but these 'massacre' type PGs always give me trouble.*Originally posted by David113***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. - 26 May '08 19:47 / 1 edit

Actually, the authors list as I gave it ("Itamar Faybish / Göran Wicklund / François Labelle & Alexandre Leroux" ) means that this problem was composed independently by 3 teams:*Originally posted by SwissGambit***I've been working on it off and on, but these 'massacre' type PGs always give me trouble.**

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.
