English question ...

What does it mean "tough" - weak/critical opening or just level of complexity and scope ?
12-16 21-17 9-14 is extremely complicated confusing opening, thats why you have many wins here on both sides, but is is even.
I can also give you several more even openings at the highest complexity and scope.
[we can drop 10-15 21-17 11-16, no problems, but I disagree with Paul Devis, Elbert Lowder, Richard Pask and whover else thinks this opening is even]
for 11-15 23-18 15-19 opening see position on the cover page of
SIXTH on the ACF website front page

and my game #20 with Ron King from WCM 2003.
