B62 Sicilian Defense: Richter-Rauzer Variation

B62 holds five named lines, all under the name Sicilian Defense. It leaves B60, a position of the same name, with 6...e6. White, to move in that position, has 48 legal moves, the third-highest count of the 80 Sicilian Defense codes. That final move, by the e-pawn, covers d5 and f5 and opens a line for the queen on d8 and the bishop on f8.
