Well, for starters, I don’t care to prove anything wrong or right, I’m just having a discussion. For second, if someone suggests a truth, it is up to them to prove it, not to others to disprove it.
But as I said in the post above, I am not talking about game theory optimal questions. What a computer or AI considers optimal is not of interest to me in this question. I’m looking at an actual human player on Black, with his/her strengths and weaknesses, and an actual human player on White. And in that world, there is very nearly zero chance that crossed opening does not advantage one player or the other.
