…But seriously speaking, my openings are nowdays really boring :c
As black i i prefer dual / “rotating” 3-4’s and then approaching on the largest side.
As white i usually play my first move on 3-4 facing the diag corner from b’s stone hoping for a cross-opening, then play 4-4 in the last empty corner.
And regardless which colour i am, after those 2-3 moves i just try to find the biggest moves.
