If you don't use a see, how can you generate good captures ? Only generating
upcaptures and equal ones doesn't give you all the good ones. It just throws
away a lot of moves in quiescence wich makes quiescence smaller but your
branching factor bigger. (randomly throwing away moves will do the same for you)
