And of course, also there's the en passant option: White queens a2 and a4, White pawn a5, Black king a6, Black pawn b7. White checks with either of his queens Qc4+ Black interposes b7-b5 White takes a6xb5 ep, giving discovered checks with both queens. Not likely in practice, but a great favourite in retrograde analysis, etc. - Anthony.
