I consider here openings in chess.com database with at least 10K, where K=1000, master games (I'm planning to extend it to 1K-core) and transitions between pawn structures. I indicate their height h and PSCC codes. U can look this thread

https://www.chess.com/forum/view/chess-openings/pawn-structure-classification-codes

for definitions. I will denote the (code of) initial pawn structure.

 

  • h=0 :
  • I --> I [1.Nf3 Réti], [1.Nf3 Nf6 Réti: Symmetrical]
  • h=0+1 :
  • I --> 1g [1. Nf3 g6, Réti: KF]
  • h=1+0 :
  • I --> 1G [1. g3, Benko], [1. Nf3 Nf6 2. g3, KIA]
  • h=0+2 :
  • I --> 2c [1. Nf3 c5, Réti: Sicilian]
  • I --> 2d [1. Nf3 d5, Réti: QP]
  • h=2+0 :
  • I --> 2C [1. c4, English], [1. c4 Nf6, Anglo-Indian], [1. c4 Nf6 2. Nf3 or 1. Nf3 Nf6 2. c4, Anglo-Indian: KK], [1. c4 Nf6 2. Nc3, Anglo-Indian: QK]
  • I --> 2D [1. d4, QP], [1. d4 Nf6, Indian], [1. d4 Nf6 2. Nf3, Indian: KK], [1. d4 Nf6 2. Bg5 Trompowsky]
  • I --> 2E [1. e4, KP], [1. e4 Nf6, Alekhine]
  • h=1+2 :
  • 2d --> 2d1G [1. Nf3 d5 2. g3, KIA], [1. Nf3 d5 2. g3 Nf6, KIA: Yugoslav], [1. Nf3 d5 2. g3 Nf6 3. Bg2, KIA: Yugoslav]
  • h=2+1 :
  • 2C --> 2C1c [1. c4 c6, English: Caro-Kann]
  • 2C --> 2C1e [1. c4 e6, English: Agincourt], [1. c4 Nf6 2. Nf3 e6 or 1. Nf3 Nf6 2. c4 e6, Anglo-Indian: KK: Agincourt],
  • 2C --> 2C1g [1. c4 g6, English: Great Snake], [1. c4 Nf6 2. Nf3 g6 or 1. Nf3 Nf6 2. c4 g6, Anglo-Indian: KID], [1. c4 Nf6 2. Nf3 g6 3. Nc3 or 1. Nf3 Nf6 2. c4 g6 3. Nc3, Anglo-Indian: 3 Knights]
  • 2D --> 2D1d [1. d4 d6, QP], [1. d4 d6 2. Nf3, QP: Tartakower]
  • 2D --> 2D1e [1. d4 e6, QP: Horwitz], [1. d4 Nf6 2. Nf3 e6 or 1. Nf3 Nf6 2. d4 e6, QP: Indian+Horwitz: KK],
