[gnugo-devel] various tuning

[Arend Bayer]

This patch contains mixed tuning. I tuned against 3.3.9, and the breakage
(here I've removed those casses that also PASS or FAIL in current CVS, but
did not check for new unexpected results) is 15 PASSes and 7 FAILs.

I have now disabled CB107 (the replacement pattern that caused the NNGS
crash), but I cannot say I am already completely satisfied with GNU Go's
behaviour in nngs1:21. The pattern that helps here is

+Pattern Intrusion54
+# ab New pattern (3.3.10)
+# X cannot play double hane.
+
+..X?
+.XQo
+!.oo
+
+:8,B,value(40)
+
+.fH?
+gXQb
+edac
+
+;(o_somewhere(a) || o_somewhere(b) || o_somewhere(c))
+;&& (o_somewhere(a) || oplay_attack(d,a,a)) && oplay_attack(f,g,H)

This makes a move below "!" less attractive.

But M6 in nngs1:21 is still the second-best move, and it is only because
of an in my opinion overvalued 't' pattern at G3 that GNU Go does not play
at M6. Adding a bad shape pattern for such keimas, as Dan suggested, would
stil make sense.

ALL the FAILs (but also a big number of PASSes) in the regression delta
are caused by my modification to A1124 (I made it more specific). However,
in all the positions where it came up, it seemed non-sense to play, so
I think the change is right and just the noise is high
(a typcial situation would be

XO.
O.*
.OX

where A1124 would make O to play at * to prevent X escaping to his friend
at the upper left).

In some cases this actually meant that there was no attacking move generated
at all, which sometimes means a change to the better and sometimes to the
worse. But then we should find better patterns for these situations.
