1.Qd6! Sf6?!? 2.S~#
Take any twomover with a threat(s). By common wisdom, anything that does
not parry* the threat(s) doesn't need to be considered, and especially
any such black move that produces multiple mates is not considered dualistic.
* Or at least differentiates, as in the Fleck case.
So far, so good. :-)
Take any twomover with threat(s) AND a random move parry against that threat(s)
which allows other mate(s) which need secundary corrections. In the above problem,
1...S~ 2.Sf5,Sc2#. By Reddmann only wisdom :-), anything that does
not parry* the threat(s) doesn't need to be considered, and especially
any such black move that produces multiple mates...hey, why was 1...Sf6?!?
a reason for a SCHWALBE rejection? Protest! Protest! :-)
* Or at least differentiates, 1...Sb6/Sb4 Java.
Any opinion on the matter is welcome, as long as it is identical to mine :-)
