Just for fun ..I set a KNN vs KP to see what the result would be --
this postion was selected just by me - I can't say at random - but with the
thought that it should take a long time ....

look at this - what happens if Black takes the knight - they get mated even
sooner

What is neat about this problem is that the best solution is to allow the pawn
to Queen and if black takes the N on 73. Kxh3 - black gets mated sooner and gets
mated by just the one and only one piece - the lowly knight. I never really
thought about this before and never assumed it was possible.
Without EGTB this is way beyond normal computers with the current programs at
this time IMO.
