It depends to defend against or to play?

Depends on definition of opening. Worst first move is 1.g4 Grob.

THE PHILIDOR DEFENSE IT S*CKS

The Grunfeld and Alekhine blow!

The cow after just a few moves and no exchanges of pieces or pawns your score is -2.00.

Reti opening is the worst

Barnes Opening: Fools Mate.

WHY IS THIS NOT HERE???

Italian game because it has blunder

Italian game tried it once and lost

i would say the Grob or the Kings Pawn Opening: Borg Variation

i like the Reti, especially if i am going to play the Intercontinental Ballistic Missle Gambit.

The Barnes Opening, do NOT push the f pawn early.

you dont know how to play the italian. remember the 40,40,20 rule: spend 40% of your time studying openings, 40% on middlegames, and 20% on endgames. the italian is one of my main openings as white, and i win pretty much all my games as white when i play the italian. also, gothamchess has amazing courses for every opening. go to https://chessly.com/
