I’m not a fan of d4 either but my younger brother and friends play so I’ll refrain from saying anything I’ll regret.
Do not get me started on the London System.
In general I’m not a fan of playing into my opponents preparation so I have a few defences or transpositions that I rotate with depending on my opponents strengths, weaknesses, my mood, time controls and tournament situations.
Really, I’m just looking to equalize the opening and get into a playable or enjoyable middle game.
I find d4 "boring"
