This nodes++ is exactly what I'm doing in my program. And to avoid to double
count nodes in search and qsearch twice i have an "if(ply==maxPly)..." where
maxPly is the depth of the non-q-search. Of course the if slows the program
a bit but then, i want to calculate #nodes and not some other obscure number
i can't reaplly explain. :)

The comparison surely makes sense. It's just that the conclusions some people
make don't make sense...
