Let's see if the new and improved Gaviota can avoid a late round collapse that plagued v0.85.1.

Fingers crossed

I hope!
The 60 Elo estimated are 10 in search, 10 in eval, and 40 elo in therapy.

DiscoCheck 4.0.1 64-bit has replaced DiscoCheck 3.7.1 64-bit.
The necessary games are being replayed.

Thank you Graham. DC 4.0.1 is doing allright so far, in terms of points.

A couple of interesting games that show some things to improve in the evaluation:

In this game, 9. Nxe6!? is perhaps overly speculative. There are some interesting idea behind the sacrifice (delaying black's developpement, and the interesting pawn pressure that white developped). But the game still ended in a draw, and I reckon Nxe6 is perhaps overly speculative, giving too much value to a dynamic advantage that will fade away and leave white a piece down.

Anyway, this game against Arasan is quite beautiful: a festival of passed pawn threats

Thanks Lucas, Ben-Hur, Adam and Miguel for contributing in this thread.

I know that there are other engine authors following too and I appreciate the interest of you all (including those who don't have a horse in the race).

Really pathetic to see how DiscoCheck left his bishop trapped on h3

bug is fixed:
https://github.com/lucasart/chess/commi ... ebc4687186
But please don't redo any testing, as fixing this bug has no measurable elo impact (I got +3.30 elo in self-play after 2000 games in 4"+0.04", could be less at long time control against varied opponents, so really not worth spending CPU time on).

Can we please just combine the results then? That way, these few games won't be wasted.

Gaviota did not choke this time, the sport psychologist worked!
