The only reason I can find, except bugs of course, that you get an even result
is that you really stop the search at 7 ply in both cases.
The Qs version ought to win "all" the time even if you set 6 ply + Qs against 7
ply without. Hmm, I'll bet 5 ply + Qs would do it if it's bug free.

You should have a time limit instead and using an iterative approach at he root
node to get some reliable results.
