Over rated? ----any half-open opening---- to quote Thajeev23,they are just played to avoid a fight and flex elo...if someone really wanted a fight, they would respond to 1.e4 with e5
Under-rated? ----almost any gambit. Many self-described" experts", typically denigrate gambits, until they face them, at which point it's the five d's of dodgeball: dodge, duck, dip, dive and dodge---but mainly dodge. If gambits are so unsound why do the very players who make that claim, decline the gambit, or even worse play lines where they never have to face them?( psst ,because those players su...su...su...yeah)
everyone is saying queens gambit is overrated
