Anyway this is usually how I like to play:
WHITE
- 9/10 times I'll open with the queen's pawn to d4 (rarely play king pawn openings or other)
- if they counter with queen's pawn to d5, i'll offer to play queen's gambit
- if they counter with knight to f6, i like to be aggressive and play the trompowsky attack, which basically brings by bishop to g5, threatening that knight, then if I capture and assume my bishop gets captured i can control the middle with my king's pawn as well, giving me situational advantage
- if they counter with a king/queen pawn moving one step, i'll bring the king's pawn to e4, controlling the centre, and then bring the knights out early to protect them
BLACK
- if they open with queen's pawn, i like to play an indian defense most frequently, which looks like this:
here my dark squared bishop (g7) controls the entire diagonal with 3 pawn protection and then I usually castle on the next move. it's quite hard to break down.
- still wanna figure out an effective counter to king's pawn openings vs white but if they open king pawn it's less effective anyway so it gives me a better chance
