Hierarchy of normal openings

[This topic concerns PSCC (pawn structure classification codes) for chess openings]

By normal we will mean any (non-advance, non-exchange, non-flank) opening where white and black have, at least, one pawn in positions c4-f4 and c5-f5 (and no other pawns in 4th and 5th rank) respectively .

Pawn height 4 = 2+2:

2Cc Symmetrical English (A30)

2Cd Anglo-Scandinavian (A10)

2Ce King's English (A20)

2Cf Anglo-Dutch (A10)

2Dc Old Benoni (A43)

2Dd Queen's Pawn Game (D00)

2De Englund (A40)

2Ed Scandinavian (B01)

2Ee King's Pawn Game (C20)

2Ef Duras (B00)

2Fc Sicilian Bird (A02)

2CDc Benoni (A56)

2CDd Queen's Gambit (D06)

2CDe Unnamed (A20)

Please suggest names for unnamed pawn structures!

2CEc Staunton-Cochrane (B20)

2CEd Unnamed (B01)

2CEe The Whale (C20)

2CEf Hickmann (A10)

Pawn height 6 = 4+2:

2CF+ can be called English Bird.

2CFc Anglo-Sicilian Bird (A30)

2CFd Sturm (A03)

The name comes from the Sturm gambit:

2CFe Unnamed (A20)

2CFf Anglo-Dutch Bird (A10)

My mind does not comprehend.

I wanna classify chess openings by pawn structures.

Ah.

I would like to classify them by how much they remind me of different foods.

Suum cuique. 😼 Take a cookie. 🍪

Pawn height 6 = 4+2:

2DEc Smith-Morra (B21)

2DEd Blackmar (D00)

2DEe Center Game (C20)

2DEf Staunton (A82)

The Staunton gambit:

I'll help bump.

Dats cool, bro!

2CFe is the vampire gambit.

2CDe could be the budapest since its the budapest minus black nf6.

2CDf could be the queens gambit dutch since white played d4 c4 and black f5

I have no idea about 2CEd though .Maybe anglo-normal scandinavian?

Bump

Thanks for your contribution! 2CDe is indeed Budapest since PSCC codes indicate only the pawn structure.

Thanks, bro!

PSCC code: 2DEFde (pawn height = 10 = 6+4).
