Just about every line of the semi-slav is as sharp as the ruy lopez, a very positional opening.
Well, in my opinion all mainline d4 openings are more tactical than main line e4 openings.
Problem is beginners who don't know the mainlines think d4 is passive:
in the last example Nxd5 is not a blunder. Qf3+ is faced with Ke6 and from what I know that position holds a slight advantage for black.
I disagree, I don't care if engines can find a draw or even the slightest edge for black, when the fried liver and lolli each score 75%+ for white in over 1000 games, white has a much easier position to play, etc, the move Nxd5 might not deserve a ??, but at least a ?.
I still think the admins should seriously consider my suggestion of limiting the entire chess.com forum to the discussion of 1. e4 vs 1. d4. People can quote "best by test" 24/7 and feel good about themselves and never worry about actually having to know anything about chess or even play the game!
Better yet create a new website for it. www.e4vsd4.com
