Subject: Most 'accessed' 6 man EGTs

I'll answer a slightly different question because:

a)  not all the 6-man (Nalimov) DTM EGTs are generally available yet, and
b)  it's impossible to say how often the EGTs are accessed
        - especially in the search-tree rather than just as root positions

So I'll quote some stats sent to me early 2004, and from Scid v3.1 beta3.

These are the top counts of occurences of positions from a 2001 db of 510,903
games:

KRPPKR	4572
KRPKRP	4553
KPPKPP	2333  ... all Rs and Ps so far
KBPKPP	1079
KRPKPP	1055
KNPKPP	 935
KRPKBP	 882
KBPKNP	 877
KPPPKP	 645
KBPPKB	 590
KRPKNP	 576
KNPPKN	 532
KQPKPP	 530  ... first appearance of a Q
KQPKQP	 509
KNPPKB	 506
KRBKRP	 441
KNPKNP	 440
KBPPKN	 417
KQPPKQ	 412 ... so Ps included all the way to here and well beyond


If anyone can give more comprehensive stats from a more recent database of
games, that would be interesting.

A theory, unsubstantiated, is that computer-computer games progress longer as
the computers don't know when to give up and can progress a small advantage
better.  A C-C db should therefore show higher %-stats than the above.
