Thanks for posting. Quite fascinating, as for the human it seems obvious that the extra black bishops don't matter. Meanwhile they seem to completely confound chess engines. Komodo (for instance) sees the draw immediately if you remove two of them...

Bad testposition as all 4 king moves draw. But article says: white can even win :?: :?: .

I think they're just referring to the possibility, which obviously wouldn't happen, of all the bishops moving off the b8-h2 diagonal, allowing c7 and c8/Q (or B) mate.

Interesting problem, but the article is just the usual Penrose bullshit on how superior the human mind is, and how this can only be explained by quantum effects.

E.g. that the largest super-computer could not solve this is of course nonsense. An Arduino Uno could probably solve it, when adequately programmed. When a computer cannot solve it, it just means it is not properly programmed. Remember that Chess Engines rank high amongst the most stupid programs ever designed, and that they are not developed to understand Chess, but just to be successful in beating other programs that do not understand much about Chess.

A simple analysis on which piece is blocking which immediately reveals that all black pieces except the Bishops have no prospect of ever moving. So it is basically 3 Bishops vs one King, and it takes only ~100 msec to generate a tablebase for that. You don't even have to realize that it helps that Bishops are on the same color can never deliver checkmate.

I guess that every strong chess engine will give a wrong evaluation but every strong chess engine will also draw this position in actual play.

The fact that the engine reports a wrong number has no connection to its drawing chances.
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.

As long as all the white pawns stay put, it is an obvious draw.
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.

Re: Penrose Puzzle

The real question isn't "Which strong engine can solve this", but rather, "Which strong engine can't solve this.

Simple inspection of the pv will show you that the big three all solve this problem immediately.

We could go so far as to argue that the evals are also correct, because there is a huge material advantage.

If the white side were to do something so foolish as to capture one of the rooks with a pawn, he would lose immediately.
