Re: Electronic checker boards (over bluetooth)

Good news! The DGT team was very kind to share the protocol with me, and after a weekend of hacking I got it working for my DGT chess board (this one still has a RS232 cable so it required some cable creativity as well). So I am hopeful to do something similar for checkers soon too! http://aartbik....

Re: Breakthrough draughts

In the final position, both have one king, so it would depend on who got the first king. That means that we have to remenber who got the first king, who got the second king etc. In addition what happen when all or a part of the kings are captured during the game? It is of course feasable but IMO we...

Re: Breakthrough draughts

Small tweak to your proposal: win = opponent is out of moves (=current rules) ELSE (first to get 1 king AND opponent gets at most 1 king) ELSE (first to get 2 kings AND opponent gets at most 2 kings) ELSE ... This similar to the rules in eg high jump in athletics: highest distance wins, then least ...

Re: Breakthrough draughts

Hi, Do you know the "breakthrough" draughts variant (I do not know if this is the correct wording)? You take the standard rules of the international draughts game but you decide that the first side with a king wins the game. With this rule the game becomes extremely difficult because you can see th...

Re: Breakthrough draughts

There are many different versions possible. In my example, you would need to keep track of the order in which kings were obtained; you could do this with numbers but not necessarily elegant. Another alternative could be to say that the first to king that survives for at least two non-hitting moves ...

Re: Breakthrough draughts

In 2003 we already played an experimental tournament with this rule, but with one difference: after a breakthrough the game continues, and the player with the king only wins when he survives. To put it in other words: a regular game is played and only when there is no winner, the victory goes to th...

Re: Electronic checker boards (over bluetooth)

It seems the DGT protocols are proprietary, but I hope the DGT team is sufficiently interested in having support from Android apps to share. I have contacted them, but no reply yet. Another interesting possibility is here . I don't know much about these board, but there must be bluetooth adapter do...

Re: Electronic checker boards (over bluetooth)

I don't know the details but IIRC there is already some infrastructure setup to display live tournaments from electronic boards and connect this to engines such as Sjende Blyn or Kingsrow. There is already software if you buy such a board. Thanks Rein. Do you know of other brands of eboards for che...

Re: Handling search inconsistencies in MTD(f)

I was wondering if people using MTD(f) are aware of what happens when there are search inconsistencies (as a result of using a transposition table) and how to deal with these situations. I wrote a paper on the subject: http://www.maximusdraughts.org/research/Handling%20Search%20Inconsistencies%20in...
