Ok this time I think I fixed the remaining time loss bug (as well as a possible crash bug). Can you try this version?

EDIT: Oops, bad compile. If you just downloaded this version. please download again.

Can you make the bugfixed source available?

It's a first time I see time loss saved as draw, and I'm going to blame the GUI. Here is the game for anyone interested:[Event "kcec-31"]

The game is drawn when a position is reached from which a checkmate cannot occur by any possible series of legal moves. This immediately ends the game, provided that the move producing this position was legal.

I like to test old engines. Many of them are unjustly forgotten, although they still play as strong as before. Most of current day tournaments are not allowing old engines to enter, so for balance I don't use new engines in my tourney.

H.G.Muller wrote:The problem is that engines are not only made for playing on GUIs, but also for playing on ICS. I don't think that ICS adjudicate draw on 3-fold rep or 50-move. They take FIDE rues more seriously than we do with comp-comp games, and wait for a player to claim. Taking out the possibility of engines to claim draws thus breaks them for playing on an ICS. Or at least make them dependent on a GUI that would (optionally) make such a claim for them in ICS mode.
In WinBoard this is not implemented; the adjudication code I added is only active in two-machines mode. Of course this could me made; I could add a option -autoDraw similar to the option -autoFlag which would claim the draw on behalf of the engine as soon as the GUI detects one. I dont know if other GUIs support such a featre, though, and if some don't that would still be an incentive for authors to have their engne claim draws.

I think this is pretty pointless. Anything you add later to a protocol has to be optional for backward compatibility, and engine authors would not be likely to use it. Existing engines would of course not support it at all.

It will still claim draw for 3-fold repetition or the 50-move rule.
