2 | Pawns advance diagonally and capture by moving forward.
5 Only the pawn movements change, but since there are many on the board it's a
6 consequent change. They move forward diagonally instead of moving straight,
7 and capture by advancing to the next square vertically.

15 The initial 2-squares jump is allowed, as well as en-passant captures:
16 after 1.d2b4 on the diagram, 1...Pxc3 e.p. is possible.
19 About notation: since pawn captures are non-ambigous they writes e.g.
20 "Pxe6" ('P' is redundant but looks nicer); simple pawn moves are often
21 ambiguous, so they write for example "f2g3" (again, the starting row is
22 redundant but this also looks better).
