| Alekhine, Slav, Scotch, Scandinavian (Center-Counter Gambit), 2 Knights and 4 Knights are next to be added. If you want to make it harder, then things like Colle System, Torre Attack, Veresov and Trompowsky (etc.) are also possible. As for 1.Nf3, either accept KIA as an answer or better yet list the moves as 1.Nf3 d5 2.c4, which is the ML Reti - nearly anything else is either KIA or a transposition.
