If you mean openings where White has only 1 decent option, no, there isn't.
At the GM Level, one could argue all openings are that way. For example, at the GM level, 2.d4 is really the only good move against the French or Caro-Kann (Two Knights and KIA lines are just equal), 2.Nf3 is the only real way to get an advantage against 1...e5, etc.
But at the patzer level, no, White can play almost anything and be fine. Scandinavian is really the only response where White has only 1 real option.
Why do you want a "forced" opening anyway? Laziness? If you want to be any good, you have to be willing to face multiple responses and be able to play more than just one position.
Hello chessers,
are there any other so called `forced openings` against white starting off with e4 than the Scandinavian ? As a low-level player I haven`t made good experiences with it ?
Any suggestions ?
