Re: 1K Real Chess for ZX80

Try to make the thinking time between the two engines similar if possible! :)
(30sec move as a mean should be good on ZX80/81)

Really curious to see the next game! :)

Thank you!!

Re: 1K Real Chess for ZX80

PS: if the opponent engine make use of a movebook, in order to level the playing field you can manually setup the starting position to the end of some known opening, and let play both engines once as black and onche as white! here some examples: http://www.mark-weeks.com/aboutcom/aa05l17.htm https:/...

Re: 1K Real Chess for ZX80

Yes, I think that the problem was about the strange ROM, since I never saw such behaviour. Regarding the board orientation is not an easy thing since various logic about pawn and castling etc, but I'll put in the todo list. What anyway I can do now is providing a version in which the black is starti...

Re: 1K Real Chess for ZX80

The en-passant should be properly managed: as said just double-step on first move of every pawn allows it. Easy to test various combination with this "flexible" version moving appropiately both sides. Also manual moves are checked for legality, with the only exception for castling in which there is ...

Re: 1K Real Chess for ZX80

I tested the en-passant and it is working. The way is the usual one: you take the piece you want to move and put it in the destination square! If it happen to discover a strange situation (this or another) please report it and I'll investigate! Good to know that alfa-beta version is stronger! Anyway...

Re: 1K Real Chess for ZX80

Hope is working! 8-) Attached there are 2 versions; one using alfa/beta pruning on 4 ply, the other quiescence search on 3-5 ply (I've still to merge of the two capabilities). Both are still without initial move logic and full optim...

Re: ZX80 porting of Super Micro Chess 1K

So, the good news seems that the engine logic is working! ;)

Regarding the move input I didn't change, and last time yourself preferred the "flicker" version! If the ROM is bugged can it be corrected there? This weekend I'll try again on my ZX80. I'll try to ask also the opinion of Paul.

In the meantime I would like just to show what I did with the trace (out 53) and some postprocessing scripts: an interactive navigation of all the engine calls equote]xecuted in the
Port 53??
