@Thomasvontom Instead, of finding best opening , I think you should do the some task like solving chess positions , study middlegame and endgame . then you will easily cross 1200 rating
Also, ya might have noticed, do yourself a favor and prep a few lines against the Wayward and the Napoleon Attack... I regularly face these still (so you will certainly too) - Things to look into are First shooing the Queen from H5 to F3, then playing Qf6 yourself, hoping for a queentrade - if they accept, ya can develop your knight and if they dont, try an antifriedliver.
