Checkmate in 517

Full-point mutual zugzwang means that whichever side is on the move will lose.

In mutual zugzwang the stake is 1/2 point, meaning that one side would lose when on the move, and the other side would only draw when on the move.

Does anyone know the difference between a mutual zugzwang and a full-point mutual zugzwang?

A mutual Zugzwang is sometimes said to be a "full-point Zugzwang'' if White wins if black is to move and loses if white is to move ie. The result changes by a full point depending on who is to move.

Thanks for the explanation.

Guess I missed that there was a second page to this thread.

The Fifty-Move Rule is the silliest in the game. It should be removed.

I've watched many a second grader chasing another's king with a lone queen while the king stands idly by--check, check, check, ...--and, thus, find a reason to support the fifty move rule. I've also muffed checkmate with bishop and knight badly enough that I would have mated the computer on move 51: the draw was a fair penalty for my errors.

There is always an alternative solution to a problem.

(The rest of your post misses the point entirely, so I didn't include it.)

The fifty move rule is steeped in tradition, although it was sixteen moves some places 1000 years ago. Novel solutions are poor alternatives to well-established ones.

And your steeped in something else.

Hello, hello!!

When was the birth of the 50-move rule?
And what was it before? ...a 30-move rule?

Any suggestions? I think the 50 moves rule works quite well.

I've been badgered for too long now by those desperate to witness an "error" on my part.

Suffice it to say that even my patience has a limit.
