I think that you overestimate the amateurs.

I do not expect Nejmet on 486 to beat palm tiger.

486 is about 3-5 times faster than the palm if I remember correctly but I am not
sure if I remember correctly the speed difference.

I guess that tiger is about 5 times better than Nejmet and it means that if you
give Nejmet hardware that is 5 times faster than Tiger the results may be equal.

If we assume that being twice faster gives 50-70 elo(it seems to be the case
based on the ssdf list) then it means that being 5 times faster may give maybe
150 elo.

I guess that Crafty is 100 elo weaker than tiger when Nejmet is at least 50 elo
weaker than Crafty and it makes the guess that tiger is at least 5 times better
than Nejmet a good guess.



I was not impressed by Nejmet because a stupid version of Movei(no hash,no
pondering,no null move,no book,only piece square table evaluation and some other
problems) played only one game against Nejmet when Nejmet lost.

The version of Nejmet was Nejmet3.05.
Movei was lucky and Nejmet fell into a trap that Movei did not plan but my
impression about Nejmet was not good based on that single game.

Nejmet outsearched Movei to win a pawn and did not understand that it's knight
was trapped(Movei also does not understand it but Movei does not claim to be a
top program or to beat palmtiger on 486 and I expect top programs to see that
the knight has no good squares to go after capturing the pawn and to avoid
capturing the pawn for positional reasons because all the squares that the
knight can goto after capturing the pawn are controlled by Movei).
