Movei is not joining in any real event where you can smell the breath of the
other programmers and seriously talk about what they do in their program and
what you do in yours. The entire CCC will not learn this to you. Same thing for
book. Also consider Deep Sjeng runs parallel at state of the art hardware.

So please try some games against Deep Sjeng at 2 times faster hardware than
movei, but even then.

See how quickly with 1.e4 the so called 'amateurs' get beaten by the Noomen
book. Also commercial engines get fooled bigtime with 1.e4.

Yet this engine gets a book which in many lines quickly exchanges to poor drawn
endgames.

Take the game against ANT.

Arturo there is playing a great line there considered += by big grandmasters.
That diep blew it a few times, but each time plays it better a few moves more is
a clear problem mine. Also book each time comes a few moves further there.

See DIEP-ISICHESS.

Each time diep progresses there if you objectively analyze it.

Bottomline is: Arturo has his lines very well prepared there, Noomen hasn't.

Rebel beats ANT in 19 moves with 1.e4 in round 1 or so.

A week time to give Sjeng 1.e4 and yet it plays a boring draw line with 1.d4
against ANT, in the sure knowing that many engines are great with bishop pair.

Only weak moves of ANT caused a very difficult endgame later on and then both
games were doing bad moves.

In short a very unclear dogfight after Qxf6.

But by that Jeroen avoids a lot of theory.

This where 1.e4 is very well prepared.

So why go 1.d4?

This is a very clear decision taken probably months in advance. Why?
Even an amateur FM player can see something is wrong there. Do not say Jeroen is
a weak player. He isn't. He's like nearly 2200 and has played a few games in
masterclass league too. He's not dumb. He's one of the greatest openings book
creators on the planet.

Yet he goes 1.d4 with Sjeng and 1.e4 with Rebel + Tiger.

If already 2 programs can go 1.e4 why not a third?

That even *simplifies* book preparation

Best regards,
Vincent
