Sorry you don't seem to like gambits in general. Let me try my best to give some positives of gambits:
- If people don't play gambits, then people don't learn how to counter them which results in gambits being more effective again. Gambits will always be part of chess theory and repertoire.
- The faster the time control, the more viable the gambit is. Blitz games can feature gambits even at very high level play.
- The most important reason - they can be fun. I have even seen master-level players on streams and videos explore gambits and have fun with theory.
I don't necessarily agree with sensationalism "crush lower rated players with [insert this opening]", but gambits will always have their place in chess.
I'm sick of all these 'how to crush lower rated players with XXX gambit' type videos. Is this all people care about, getting a quick win by reciting a few moves by rote? At best, you'll improve your rating for a short while but then get kicked back down when you have to actually play real chess. I don't think we should be encouraging this sort of thing. I really want to yell at my screen when opponents play some stupid gambit that they've been told will let them 'win easy'.
