To me solid is the opposite of "sharp". But I don't know. In my view, below master level, there is no such thing as a drawish opening.
Difference between solid and drawish??

Play openings you are comfortable. Don't bother with theories saying this opening is solid. drawish, double-edged, etc. In amateur chess, there is no drawish openings, middle games and endgames. Tactics and mistakes decides the game.
Its told a lot that the caro kann is drawish and solid and the french is solid. Whats the difference? Is the Queens gambit declined drawish or solid? Does solid mean good position but not much to play for?
