i wont claim to know anything much at all. But if it's a game i feel i really need to win, I stay with standard openings with black for a few or 5 moves, to try to get my development keeping up...then at the 1st opportunity, i try to do something that is, or at least looks like it is, a threatening move. Try to get white reacting as soon as possible. I do much better when its me doing the pushing. Passive play for me, is always losing, feels like.
Better players will likely have much better answers.
(I think this the right forum for it)
Let's say (in daily chess) there's a game you need to win with black. (assume your opponent is roughly the same rating as you)
1. Do you play the openings you normally play and hope for the best or do you deviate and play something dubious?
2. If you do play differently, what are some openings that give black good attacking chances to secure a win?
