Well, I think 5 years is not enough... -> tomorrow I will publish the truth
about it. In fact he just changes some text-infos in Pepito 1.59 and that's it.
I found in the engine the same bugs then Pepito had, the same set of commands in
console mode, the same board representation and when analyzing a position with
same settings the same number of nodes, the same eval and the same pv... which
can be reproduced with any position you may try. Yesterday I got another version
of this crap where he changed some text output and some other things... (he
changed e.g. the config file commands but his own config file was wrong so that
it does not read correct pawn hash and egtb-cache values...) Maybe he has
changed one eval parameter, because the node count differs now by 1-2% - anyway
the pv stays nearly the same to Pepito 1.59 and the score still is equal... so
the node change might be also a consequence of the different hash settings... To
me it is more then 100% proven that it is an absolute clone - and the man behind
it ... oh well, I have no words for such persons...

Greets, Thomas
