I am not sure what you are asking / suggesting.

That's certainly a difficult ending without EGTBs. But with, it is quite easy. Crafty sees it instantly:

Hi Bob,
yes with tbs it is easy to win.

My question is:

Is it theoretical possible to win such a game with eggbs too when they are correct implemented?
There are several engines which use eggbs instead of tbs - Scorpio loads it comlete into RAM and I think Toga use eggbs similar to tbs.

Looks like it is not possible. Shredder using only his Shredderbases fails too:

Aha, now I see the question. And yes, BB's are a problem since they do not allow you to differentiate between different moves that lead to mate. All you can do is depend on the repetition detection or 50-move rule to save you and force you down an alternative path. But with just one pawn on the board, this isn't going to work.

This is exactly like the case at the first ACM chess tournament in 1970, where COKO used a simple mate score, not the distance from the root to the mate. And it kept playing a mate-in-2 move until it screwed things up and actually lost the game. bitbases are more a "classification" algorithm so that you can recognize that a position is won, lost or drawn when you encounter it, but at much lower cost than with a full EGTB set. But once you get to the 5 piece ending, you either need real tablebases, or a good evaluation, as the bitbases are not going to help once you get there. They just let you know that "getting there" is a good thing...

Re: Win with eggb usage possible (Scorpio, Toga, Cyclone)?

Post by bnst »

What if a program switches to a new mode when it gets to a won position in the EGBBs. It would search as many plies ahead as possible to find a variant where a pawn was moved or a piece hit or of course a win. If such a path is found you would know that in some sence you would get closer to the mate. You could also use the hash in a much better way since it only needs to store one bit for each position.

With todays big hash tables perhaps this program would find the mate in all or almost all cases - at least those which are within the 50 move rule.

I think it would be an interesting experiment.
Probably somebody already did this.

This position can be solved by retrograde analysis in just a few seconds, provided a bitbase for the promotion positions (a subset of KQQKQ) is available. So indeed the engine would do better to switch to this mode.

Infact , all the engines Werner tried do that. But as it turns out sometimes in positions like this one, you need to have complete information to solve it within the 50 move rule. The problem is all bitbases provide you is a WDL score, so the engine should try to prefer moves which seem to make progress and also prefer "simpler to win positions" by evaluation . For example prefer a straightforward 5men than the KQPKQ etc.
Inside search if all bitbases probes after pawn moves and captures are immediately returned because they zero the 50 move count and give the engine more time to find the path by search. If not the engine does not do immediate cutouffs for 2/3 of the total search depth. To prefer different mates we usually return (-MATE + ply) from search. In a similar manner the bitbase score's are corrected depending on where the egbb is probed. This sometimes can get screwed up by the hashtable.

With this method scorpio solves most positions PROVIDED that a full blown search without egbb can guide the way to the mate. In this particular case the queen checks are too much for the search to spot any winning paths. Here is egbb probe code in scorpio

Code: Select all

bool SEARCHER::bitbase_cutoff() {
	/*
	Cutoff tree only if we 'think' progress is being made
	   . after captures
	   . after pawn moves
	   . or just after a certain ply (probe_depth) 
	*/
	if( egbb_is_loaded
		&& all_man_c <= 5
		&& &#40;ply >= probe_depth
		|| is_cap_prom&#40;&#40;pstack - 1&#41;->current_move&#41;
		|| PIECE&#40;m_piece&#40;&#40;pstack - 1&#41;->current_move&#41;) == pawn&#41;
		) &#123;
		/*
		Probe bitbases at leafs ,only if they are loaded in RAM
		*/
		register int score;
		if&#40;&#40;ply <= probe_depth 
			|| &#40;egbb_load_type >= 1 && all_man_c <= 4&#41;
			|| egbb_load_type == 3&#41;
			&& probe_bitbases&#40;score&#41;
			) &#123;
			
            egbb_probes++;
			
			/*prefer wins near root*/
			if&#40;score > 0&#41;
				score -= WIN_PLY * &#40;ply + 1&#41;;
			else if&#40;score < 0&#41;
				score += WIN_PLY * &#40;ply + 1&#41;;
			
			pstack->best_score = score;
			
			return true;
		&#125;
	&#125;
    /*
	no cutoff
	*/
	return false;
&#125;
The egbbprobe has an evaluation which does preferential treatment of positions (material score, king closeness to pawns etc...) You can also use the regular eval function there for that purpose.

The problem is the depth. some of these are way beyond any search depth the program can reach, before the first pawn push is supposed to happen. Alpha/beta depends on bounds and scores to pull us toward the right position(s). When all you have is "won or not won" you don't have enough information. The general solution is to use the bitbases in the search, and when you get to a root position that is known, switch to regular egtb accesses..

"few seconds" depends on the position. Probably not for 6 piece endings and beyond...

One could always try a variation of the "swindle mode" in crafty. Where at each ply you generate moves, and cull losing/drawing moves and use a normal search on the resulting tree to try to make progress. But there is no guarantee it will work in all cases unfortunately, while swindle mode is always safe...
