    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

    I've been working on it off and on, but these 'massacre' type PGs always give me trouble.

    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.

    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:
    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.

    SOLV'D, though I must admit the hint from the previous thread was a big help.

    It's almost a month since the first post (in this thread).

    I can't get it less than 14.5, can any one help me.

    The hint on the previous thread should help. Did you see what that was?

    If you are talking about "rundlauf" (did I spell that correctly?) either I don't understand it, or it's not helping me enough.
