What's the best chess opening for white or the best opening for black? Why?
I like the Queen's Gambit for white and not only because it has the highest win rate but because of the solid positions that can be developed from the Queen's Gambit.
Here's a good example of a Queen's Gambit declined game and game positions, this was a game I played with a 2000 rated player.

As you can see, black lost due to a mistake and I punished black's mistake and eventually made them lose. This shows the toxicity of this opening, one small mistake and things can easily go downhill.
Here's another game where I turned the tables against my opponent in another heated Queen's Gambit position.

These games clearly show why I love the Queen's Gambit and why you should play it too! Stay tuned for more informative chess tip forums.
