Subject: Selective Analysis in Crafty or Fritz 6a

Author: Steve Schooler

Date: 23:22:06 12/17/00


From base position, wish to manually identify several candidate positions and
then use engine to analyze _only_ those positions (overnight) to specific depth
or time expenditure (e.g. 15 ply for each manually identified position, or 10
minutes for each manually identified position).  Failed attempts with Fritz 6a
and Crafty described below.  Request anyone's help, any workaround involving
Fritz 6a, Crafty, or any other Freeware.


Fritz 6a:

Deep position analysis allows no selectivity of positions to analyze.
Alternatively, if each candidate position is represented by a separate (FEN
specified) database entry, apparently no way to automate retrieving each entry
from database, analyzing to specified depth, saving analysis, and then
proceeding to next database entry.

Desired process is similar to Fritz 6' "test suite" processing, except
a.  Don't wish to specify any best move or avoid move in the positions
b.  Want to record/save analysis, not "test score".

Desired process is also similar to blunder check of one game (including blunder
check of all variations) _except_ that:
a.  Only wish to analyze stub (last move) of each variation, including main line
b.  Ideally, wish to analyze _after_ each stub, rather than each stub.


Crafty (v 17.14)

Tried to automate investigation via Analysis command by using Crafty.Rc and/or
redirected input stream.  Couldn't specify analysis of multiple positions where
2nd Analysis step _waits_ for 1st Analysis step to satisfy search depth.

Similarly, automation attempt via Annotate command apparently forces all
positions into one PGN file.  Consequently, couldn't find clean way to
"annotate" _only_ candidate positions.
