RE: [pbmserv-dev] Cathedral edge case

[Lyman Hurd <LHurd@mediabin.com>]

Does "you can not capture on your opening move" mean that you cannot make a
move that in later play would have the effect of capturing something, or
doees it mean that you can place the piece there but the capture won't
proceed?

Forgive if I am being dense.  Still a Cathedral neophyte.

I agree.  That's what it *should* do.  But I'm having trouble codifying
that.

specifically.  the rules state, you can not capture on your opening move.

So, I put code in there that if the amount of territory being "captured"
is more than 94 (10x10 - 6)... it's too early to capture.

The max territory that allows for a capture is...

1 CAnB6        2 STnI9
3 TAnJ10       4 BRnj7xCAxTA

Yes...  STnJ8 and TAnJ9 should also work.  But the amount of territory
captured then in too great for the earlier algorithm of thou shalt not
capture on placing a single piece code to deal with.

I could make the code simply ignore the 1st move of each player, but then
I could place  TOnC1 as my opening move (assuming it's clear) and I'd
capture A1,A2,B1 for future moves (once the capture code "turns on" later)

The code is open for audit... PLEASE!
