Well, i disagree. If Quark can play with Fritz8 book and inside Chessbase GUI
for example, 130 points stronger from Leo's list = 2677 , while Smarthink for
example doesn't have any combination of book and GUI to be able to play more
than 20 points stronger = 2643, i will definitely say that Quark CAN be stronger
from Smarthink, so Quark IS stronger from Smarthink.
