I do. There was a chess player named Richard who posted here long ago who once under-promoted to bishop six times in one game in an effort to shame his opponent into resigning.

That's way more interesting and humorous than some quick bludgeoning.

If you have your GUI set to accept tablebase draws, and the six man files, the game will draw instantly.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I do too. The point is that the engine doesn't know the strength or disposition of the opponent. In which case, why should it dare to allow an easy or instant draw?

I already explained it, It all depends on the time left for both engines, if the engine that can draw with 2 moves only has 1 second left on his clock it is logical to draw with 2 moves, but if it has more than 1 minute left and the opponent only has 1 second left it is logical to make the game as long as possible to see if his opponent run out of time. It does not has anything to do weather it assumes that his opponent is strong or NOT. I have lost several games on time control when I am winning 2 Rooks to one Rook, but my opponent knew that he had at least 2 minutes left whereas I only had no more than 5 seconds left on my clock. Take BIZMARCK remark for example https://www.chess.com/forum/view/genera ... -positions.

A simple example: Let's say you are white here with low time (<5 seconds). You panic and start checking your opponent with your rook repeatedly while trying to checkmate them, but you end up losing on time (hypothetically).

NOTE: The reason why I believe it is illogical to prolong the game to 50 moves is because I do NOT use tablebases and never ever had, and for some engines to select the longest draw is very illogical[/pgn]

Just to prove a point the latest version of Stockfish 16, thought that it could be a Dumb Engine, but DUMB show Stockfish that it is NOT that easy to lose on time, with only 1 second per move :mrgreen:
