What sequence of opening moves can include most different named Openings or Defenses by transpositions?
For example, I just played a bullet game that went:
1.d4 e5 2. e4 d6 3. Nf3 Nc6 4. Bb5.
In this sequence, we have, in just four moves:
Queen’s Pawn Opening; Englund Gambit; King’s Pawn Opening; Center Game; Philidor’s Defense; Ruy Lopez; Steinitz Defense to the Ruy Lopez;
Very interesting is also:
1.e4 d5 2.d4 c6 (or 2...e6), and so on.
Are there any other similar (or better) examples of this kind?
