Project Euler Forum

In "Game Theory" "shortest chess game" in the text things appear (in firefox as well as internet explorer) like

Fool's Mate has length 4 + 4[radic:206bc5ffbc]2; is there a shorter game?

I repeat it with a blanc in front of radic, for the case, it is interpreted in other systems.

Fool's Mate has length 4 + 4[ radic:206bc5ffbc]2; is there a shorter game?

I am afraid, the original text has been changed in some way.

Thanks for pointing that out ThomasH. I was re-writing part of the forum code that would allow easier (from my perspective) addition of new BBCode style symbols and it caused previous posts to not display properly. I thought I had gone through and fixed them all, but clearly I had missed one. All sorted now.
