I increased the limit from 60 to 200 at the cost of an additional ~150 kB.
But that's not important since its just a global array that will never be used.
I believe it is then safe to stop the search at 150 plies, that's 50 plies left
for extensions(!), it will simply have to do, even if I get a crash in 1 of
10000000 games ;)
