Hello: 4r3/2k1p2q/pp1nR1p1/2pP1pP1/2P2P2/1P6/P1K3B1/4Q3 w - - 0 1 I was unable to locate the origin of this position, but it is either published wrong or a real pain.

Re: Some top engines solve this instantly, but humans?

Hello: I got the key ideas on the second position, trying to stalemate the white king with c6 and b5 while getting rid of the white rook and the h-pawn. Nice indeed! I searched the first position. The original post and the key word is swindle : black is winning (white is lost in 19 moves according t...

Re: Impossible to access the WinBoard forum.

Hello Roland:

I get the same error. However, I can access the forum with Google Chrome if I click on the upper right message 'Return to index page'. If you leave the forum and do not clear browser history, you can reach the forum again without the SQL error.

Regards from Spain.

Hello: Your connection is not protected. Certificate in the certificate chain is out of date. :shock: :cry: Same here.
