7 | A piece making a multistep move can be captured by an opponent's piece | |
8 | guarding a square on its way; this capture is only possible right after | |
9 | the move (same condition as for en passant pawns captures). | |
10 | li. | |
11 | Even if the capturer gets captured en passant on next turn, | |
12 | the initial captured piece does not return to the board. | |
13 | ||
14 | p This is a generalisation of the pawn en passant capture, which is still possible. | |

20 | Knights become knightriders, which may make multi knight-steps in the same direction. | |
21 | For example in the standard initial position, the knightrider on g1 | |
22 | can go to e5 or capture d7 in addition to the knight moves (see diagram below). | |
23 | li The king can capture a piece en passant by making a knight move. | |

33 | Due to the extended knight movement, a capture, check or even checkmate | |
34 | could be played at move 1. On the following diagram 1.Nxe7 is mate, | |
35 | and black in turn could play 1...Nxg2 trapping the queen. | |
36 | Consequently, captures are disabled at move 1. | |
