Let's have a look at this:
And see how Black loses a pawn for nothing, by following them "tips" yeah, develop, yeah connect the Rooks, etc.
Go after tips and such, and you'll lose many games in the frst moves for not knowing a secondary opening.
An other example: my opponent is a Queen's pawn player, and plays that (1.d4) every time with White for 10-15 years. Let's see how it goes for him as he's playing Black against me:
It took him over an hour to play like 8 moves out of 40 he needed to play in 2 hours, and ended up in a King's Pawn opening reversed with a move less than should, taking ages to play moves that fit the famous "tips" of my bottom.
He eventually lost for playing mediocre moves in a position that was so totally unfamiliar to him.
I could multiply the examples, and trust me, I've got tons of them, taken from real chess competition. But I won't work any further for getting "thumbs down" from people who care for what's impressive and easy rather than for the truth.
Don't comment on ongoing games of other people.
