The disadvantage can be a big problem only in blitz if it cause Ruffian to lose
on time but it is possible to prevent the problem even in blitz by giving
Ruffian small hash.

Note that I did not consider the time of clearing hash tables as a disadvantage
in my previous reply because I assumed that clearing the hash is almost 0 time
relative to the time that is used for calculating and it is the case in
tournament games.
