In the Chessbase-Help to Shredder 7 there is the following text for settings for
a shootout:

Skip even plies: allows you to avoid the weakness of some engines at even plies.
In the above example, setting 5 – 9 plies and skipping even plies results in
three games (at a search depth of 5, 7 and 9). Since sides are changed after
each game, we have a total of six games in the shootout.

I wonder too, why even plies should result in weaker moves and I didn't find any
 more detalied explanation in the chessbase-help.
