More or less equal, according to analysis

the grob gambit is the worst bruh

The Grob Gambit is actually sharp and can be dangerous for Black if they don't play properly.

ok

o wait they can win a rook

botez gambit

The Botez Gambit. 😂

The Pepsi Opening: Coca-Cola Gambit is pretty bad. 1. g4 g5 2. f4

There are several GM's having played this. There are also several books that mention this variation and in the book: Starting Out: Sicilian Grand Prix Attack this is mentioned as one of the critical variations by GM Gawain Jones.

It may sound funny to some people, but this is a critical variation of the closed sicilian. Its not bad at all. (However, you dont get there from playing the scandinavian move order. Nobody in their right mind would play 2.f4 against the scandinavian)

Is there a consensus on the definition of "gambit"?

1. e4

In my Chess club, we forbid gambits to be played in rated games. Violators get a verbal warning, next they get "written up" and, lastly, suspention from the club for 3 months and upon returning they must pay a $20.00 fine. Those who wish to play gambits in offhand games must do so in a separate room and only if they get permission from their opponent. We will not tolerate or encourage unsound play. Sure, some have angerly left the club because of this policy which we have had for years but we are, nevertheless, a quite successful club and ready to face any legal challenges to our "house rules".

what if the gambit is sound like the milner-barry gambit?

The avalanche gambit.

Such a request would have to be submitted to our Competition and Ethics Committee and, if it deems it to be "not too insulting" to the Royal Game, it would be allowed. The Queen's Gambit is approved since it is deemed by most authorities to be not a true gambit. We cleared that up years ago. We once had a player, albeit only having less than an 1100 USCF rating, showing an analysis that Black could hold onto the pawn in the QGA. Black's position was so bad by doing so, we permitted it to be played. We also have an "unwritten rule" that if Rook pawn moves by either White or Black on the first move whether it is a rated game or not, the opponent can laugh loudly for 3.5 minutes (on their own time, of course). The bottom line is that we have put in these rules to maintain the integrity of proper Chess play. If one does not like it, go to another club.
