Gaviota TBs and the 50-move rule

Post by Norm Pollock »

I have tried to contact Miguel about this problem but I do not know if he has received my emails. So I will post this issue here.

The following game with Critter 0.90 using GTBs (on a flash drive) against Houdini 1.03a in Arena 2.0.1. My old w32 XP was used. Time control was 1'+1''.

The comments show that the GTBs were used by Critter. After black's 70th move, there are only 5 pieces left KRkrb. The same 5 pieces dance around for 50 moves or so. After black's 119th move, the game crashes with "rules infraction / illegal move" messages. Critter is undeservedly given the victory.

Is there a log file showing Houdini's illegal move ?
My engine was quite strong till I added knowledge to it.

Hi Norm,

Probably you sent an email to my old @msu.edu? I do not work there anymore. The email that I check for CC is at the bottom of the license here
http://sites.google.com/site/gaviotachessengine/license

I should make the contact information more obvious. My bad.

Looking at the game, it looks like GTBs are not related to this. Critter defended well using GTBs and Houdini (which was not using GTBs, I understand) must have done something wrong just at the limit of the 50 move limit. It happens with some engines that they believe a draw was adjudicated already and their output is not appropriate. Contact R. Houdart about it because I think it is Houdini's bug.

The following game with Critter 0.90 using GTBs (on a flash drive) against Houdini 1.03a in Arena 2.0.1. My old w32 XP was used. Time control was 1'+1''.

The comments show that the GTBs were used by Critter. After black's 70th move, there are only 5 pieces left KRkrb. The same 5 pieces dance around for 50 moves or so. After black's 119th move, the game crashes with "rules infraction / illegal move" messages. Critter is undeservedly given the victory.

Re: Gaviota TBs and the 50-move rule

Post by Tom Barrister »

Houdini's 120th move looks legal to me.

The illegal move notice occurred right after White made its 50th move following the last capture/pawn-move (at Black's 70th). Black should have been entitled to a 50th move as well, at which point the game would be adjudicated as a draw by the 50 move rule.

I'm not a programmer, but it looks like Arena made the error here.

Re: Gaviota TBs and the 50-move rule

Post by Norm Pollock »

Looking at this a day later, the 50-move rule does not even apply to this situation. White's 120th move which is the 99th half-move of the 50-move count, is a forced capture. That move did not occur because of the crash, but if it had occurred, it would have reset the 50-move counter before Black made its 120th move.

I have no clue who was at fault. I have tested Houdini on the 50-move rule and it works fine.

Obviously Arena adjudicated based on the black (Houdini) move 119...Rf1+. Although this is only the 98th move of the half move clock as you correctly (indirectly) stated, I think it is very likely that the problem is related to the 50-move rule due to the closeness of the position to the 100th half move. The question is still open whether there was a fault by Houdini or Arena. After replaying the game I get the impression that the Houdini output was correct so it could be an Arena problem of maintaining the half move clock correctly.

Whenever two engines play correct moves but the GUI claims an illegal move, my first thought goes towards the GUI. Of course it could be possible that an engine outputs a correct move along with a wrong draw claim or similar.

When a GUI forfeits an engine on an illegal move, without actually telling the user what that move is, it is by definition a GUI bug... :(

Correct !

My question was a hint at what you have openly said:

"Is there a log file showing Houdini's illegal move ?"
My engine was quite strong till I added knowledge to it.
