With nightrider (shown as inverted knight), after Black moves his pawn to e5, taking it en passant results in triple check.

In chess with variant rules or fairy pieces, other ways of delivering a double check may be possible. Triple, quadruple and even quintuple checks may also be possible, for example in the position shown, after Black plays 1...d5, White plays 2.exd6 e.p. quintuple check (the moa is a non-leaping knight which first takes a diagonal step, then an orthogonal one). After the en passant capture, both moas, the rook, the grasshopper and the bishop check the black king.

In xiangqi, a Chinese version of chess, triple check and even quadruple check is possible even without using fairy chess pieces, as in the following examples:

    “And we fairies, that do run
    By the triple Hecate’s team
    From the presence of the sun,
    Following darkness like a dream,
    Now are frolic. Not a mouse
    Shall disturb this hallowed house.”
    —William Shakespeare (1564–1616)

    “He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll check on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
    —Elizabeth Wilson, U.S. crime victim. As quoted in People magazine, p. 88 (May 31, 1993)
