I was talking about 1. c8(Q)+ Nxe8 2. Kxe8 ... 3. Nf6 ... 4. Nxh7 which results
in KNNK. I did not realize that Bill was talking about 1. Nf6 ... 2. Nxh7.

Now granted, in this position, e8(Q)+ is an inferior move to Nf6 as a first
move, but there may be positions where this is not the case.

The position was not meant to be accurate, but rather to illustrate the point of
 1. e8(Q)+ Nxe8 2. Kxe8 potentially leading to a win, regardless of 50 move
rule.
