Piece/square table challenge

Can a chess engine with pesto evaluation beat 2000+ player?

I'd imagine so. There are several engines I'm aware of that had only piece-square table evaluations and play at a level of 2000+ Elo on the CCRL. And generally, from what I understand, engines are often rated higher when playing human opponents. So a 2000+ engine should be able to beat a 2000+ rated human player.

Of Course.
It already got 3098 elo

The more interesting question is if some GM who know the pesto piece square table can use the weaknesses of it to beat it in a chess not by a prepared line(some different engine may play in the first 8 moves of the game against prepared lines).

Indeed, a good game, until 25.Qa3 which is a massive blunder. If 25.Qe1 Bd3 26.Qxe6 the game is probably a draw.

It would be nice if this contest were resurrected. I would like to see MCE's tables compete. And the tables of Sam chess. Sam's are initialized by algorithm at the beginning so I do not know the numbers. However, Sam is elo TSCP 1.81 + 252.

A fascinating project. I note PeSTO uses Syzygy endgame tablebases. This mean no basic endgame knowledge is needed. I'd be interested to see its strength without tablebases. I suspect it'll be a couple of hundred ELO lower.
