Re: New engine releases 2019

Yes, it seems it jumped from 2141 to 2509 in 40/4, which is way above my expectations, so I better wait to see if that is correct :mrgreen:

Re: CCRL 40/40, 40/4 and FRC lists updated (4th May 2019)

Big thanks for testing Tunguska 1.1, got 2509 (previous version is 2134). The funny thing is that I fixed a lot of problem with my qsearch, which is giving me 55% against the github version :shock:
The 40/4 list still showing the 1.0 version though (and I'm Brazilian, not Spanish) :mrgreen:

Re: Tunguska 1.1 STS test results - improve eval

Cool, I'll look into material imbalances.
Regarding the "run away", can I use SSE to help?

Something like

if (isCapture(move)) {
if (see() == 0 and relativ_material >= 0){
move.score = bad capture score
}
}

Re: New engine releases 2019

I was ready to post my updates to Tunguska, so it's nice someone already did it, thanks!

It still pretty weak, but certainly ~100 ELO stronger than the previous version.

Re: Tunguska engine v2.0

Yeah, I remember that I have changed the eval code some weeks after my first release here, so I believe that the tested version is not the current one on github.

There's no 2017 update because yet, but I've just started working on code to tune the engine.

Thank you!

Re: king safety and castling ?

My engine castle most of the time, but not as fast as I wished. It
sometimes loses the castle against much stronger opponents, when they are attacking.

Do you guys score castle moves while searching? I didn't.

Re: king safety and castling ?

I'm my engine I didn't handle castle eval yet, since it castles 'naturally' most of the time. But sometimes it loses the right to castle (against much stronger opponents): I'm planning to add something like: //The same for QS if (hasRightsCastleKS() && canCastleKS() && ksWingIsSafe()...

Re: Stockfish's passed pawns assert

Ah I missed that, now the assert makes sense. Thanks!
