Tf6-a6 b5-b4 5. Tf7-f6 b6-b5 6. Sh8-g6 | Black pawns: fxe,gxfxe. White pawns: gxf,hxgxh,b| If Black castling rights remain, then the cage in the East can only be unlocked by wTf7, White double pawn retraction of some kind is necessary to let the rook through. Example retraction: R: 1. a2-a4 c7-c6 2. Ta3-b3 d7-d6 3. Ta6-a3 e7-e6 4. Tf6-a6 b5-b4 5. Tf7-f6 b6-b5 6. Sh8-g6 Multiple ep can never be handled by Retro Strategy. Instead, PRA protocol is needed. But the assertion that Black castling rights remain seems to precede the PRA division into parts, which only includes the three possible ep, exactly one of which must be legal. |
