Four Knight what though? There are so many Four Knights.
Whats your favorite opening

What kind of opening is that??
Smith Morra Gambit. Just take a look at this game to see what its capable of.

My favorite openings are the reti gambit

Also, for white a good opening against the indian in my opinion is the paleface attack
Creates very good games of attack. stockfish doesn't like it (gives it -0.8), but it's hard to find a refutation against this. Even if the opponent plays d5, you can go for a richter veresov attack with nc3 and bg5 Where your wish is to push the pawn to e4 and most of the times, white will equalize fastly and have big attack
mine is the 4 knights game
