Thanks to Eugene and subsequent correspondents for pointing out the gem
positions with double check by queens. Chess has an infinite ability to
surprise and delight - and these positions also warn of the dangers of inducing
rules from partial considerations.
Eugene's example shows that double check is possible in KQQKQQ.
Anthony Bailey's example is not in KQQKQQ but is equally splendid nonetheless.
For the convenience of any other readers, the positions were:
(eg) K7/QPk5/8/8/8/8/8/8 wtm ... 1.b8=Q+ (double check by 2Qs)
(eg) 7K/1p6/k7/P7/Q7/8/Q7/8 wtm ... 1.Q2c4+ b5 2.axb6+ (ep & dblech by 2Qs)
Nothing to do with double check by Queens, but this position eluded me for a
long time:
8/1P6/8/8/8/K7/8/k7 wtm ... 1.b8=Q or 1.b8=R stalemate!
ergo, you can't always 'run the P' to win when the bK cannot catch up!
