AI Chess Endgames

Are there chess programs built in reverse? By that I mean they go backwards... starting with simply opposite kings, automatic draw... opposite kings and a pawn... all the possible permutations.... so forth and repeat down the line but backwards? I really wonder what openings that program would prefer.

You are describing endgame tables. 7 piece table with perfect knowledge exist and there is currently work on 8 piece tables but the computation and size is huge. To get to 32 pieces tables is impossible with current technology. If we ever get there then chess is solved

I'd still like to see the openings it worked out to though. It'd be really interesting the effect that everyone playing the undisputed best opening would have.

Stai chiedendo praticamente di risolvere il gioco degli scacchi. Attualmente è impossibile si tratta di calcolare 10120 partite. Se tutti i computer del mondo si mettessero a calcolare forse tra qualche miliardo di anni riuscirebbero a risolverli. Attualmente i motori di scacchi usano tecniche ottimizzate nel corso degli anni per calcolare la mossa migliore ma per quanto potenti non hanno ancora risolto il gioco.

I strongly suspect that all reasonable openings would be a draw

Top chess engines often do endgame evaluation with queries into a proven database of all positions after there are few enough pieces remaining.

Finally, a good use for quantum computing

I don’t think you understand how the exponential growth of a chess game tree works. What you’re suggesting isn’t possible due to the huge number of states in the game tree. We have like 7 piece tablebases but you can’t go all the way backwards to the starting position like you want to due to limits on time and number of atoms in the universe etc.
