@karlgoethebierThe London system is a good choice. But 1.d4 c5!? what will you do? Best 2.Nf3 cd4 3.Nd4 Nf6 4.Nc3 Nc6 5.e4 - the Sicilian defense. If 2.e3 Is the Debut Colle, which is not very good for white games. IMHO.
If 2.d5 Is to defense Benoni and the Volga gambit. Play Owen too dangerous. White are +0.60 and you will only suffer. The most minimal option 1.c4 - English opening for white. and 1...c5 Sicilian defence and Volga gambit for black.
But if black really wants to play the king's Indian defense and defense of Pirca-Ufimtseva, you they can not stop it. This is the way the second plan minimum opening repertoire as white to play the king's Indian beginning.
If you want to win, it is better to solve tactical problems, Lichess. I'm doing that.
