hippopotamus attack or something, lol. Nimzovitch def is also good.
What is your favorite opening?

Queens gambit I use for lighting because people (some people) are like how to counter that hmmm.... here what happens somtimes
Dumb way mate

White: Ruy Lopez, general king pawn game, Queen's Gambit, Pirc Defense
Black: King's Indian Defence, Old Sicilian, Paulsen Sicilian, Caro-Kann Defence

As white the Bishop's opening is reliable. vs e4 The Sicilian for his energy . Vs d4 the Dutch Stonewall is a filler but I'm still looking for the real one

I just love playing the Ruy Lopez as white and french as black. I do experiement with 1: d4 as black, currently playing the Nimzo-Bogo system
fried fox. it's good to confuse your opponent.
