Re: Rook Bonuses

hi KLO

I have already started playing with this idea way back when i released Ivanhoe B47f0.2 with some promising results in longer time controls but bad results in shorter time controls.I have added some knowledge in evaluation.c regarding the Rooks and Queens and gave huge bonuses when on certain squares and when certain conditions were met.It was basically just an experiment and probably a premature release,i would not really call it an "official" release of mine.But anyway....

But the conditions were very primitive and can be more clearly specified in future releases.It does not really hurt speed as also mentioned and confirming what Uly here said.Since it only runs that code when that specific conditions are met.

I see even Ivanchuk appreciates this idea in his round six game of the Bilbao Masters tournament :)
At the right time the rooks are very much needed on the 3rd rank i am convinced there are ELO locked away in that idea :) When it can be specified correctly with the correct conditions.
Unfortunately since my release of Ivanhoe B47f0.2 i did not have more time to even look at the Ivanhoe code again,but who knows,perhaps when i find time again,but i would certainly encourage you to continue this idea,and lets see where it leads.

Best Regards
Izak

Just an anecdote from a game I played yesterday (moves recalled from memory):
And here I missed the most direct 23. fxg5 (hallucinating that Qxe5 might hold), but won quickly.

This is the kind of position I envision with the queen and rook, and right color bishop (though in the case both bishops) threatening the king when thinking about bonus for Rooks getting on the 3rd rank. I would say this game kind of flowed towards that.




IvanHoe (1 core) on move 17 preferred c3-c4 at first, then chose Rf3, then back to c3-c4. I am not sure if the material weighting with respect to the static weighting is a little high. I think Rf3 should have been the first move and the engine should immediately recognize the threat it poses.
