I've done some experimentation of this sort, but rather than quote my own
experience, I'll point you to reports by people who have spent more time
on this than I have. BGOnline is having some server problems, but I think
these links should work:

The upshot is that GNU 2-ply (version 0.xx) or XG 3-ply (version 1) is
reportedly exploitable in this manner, if you play money games with an
unlimited cube. Stronger settings are reportedly harder to exploit, but
maybe not impossible.
In any case, as I said earlier, in my opinion this line of investigation
is not really the most interesting one. IMO the closeness of a bot to
perfection should be measured not just by its performance from the
standard starting position, but from *any* position that could legally
arise in a game. The reason is that in practice, bots are used to analyze
positions that arise in actual games. It's obviously a logical error to
conclude that the bot's analysis of an arbitrary position is sound just
because it plays well from the starting position, but I'm surprised to see
how often I see people implicitly making this error.
