GNU Bug...or another in need of psychiatric help...?

Post by sigma » Thu Jun 28, 2007 11:03 am

Hi

Tell me if I'm just crazy or if this is a bug on the GNU Engine...

To get to the point where the "bug occurs", follow this path:

http://www.net-chess.com/gnu/gnumove.cg ... &move=g2g3

Then, move the white king, from D1 to E2 (Which is an illegal move, as you would be placing your self into check, via the Rook on E8). The GNU Engine, however would promptly respond by moving the black bishop from C8 to G4, subsequently placing you into a check mate you should theoretically not have been able to get into.

The end result is as such...

Am I crazy? Can someone suggest a good shrink?

Regards

Sigma

In this case the solution is easy. You switch sides and send the com to the shrink ( I think the name of the doctor is Greg Miller) :D

Well, at least I know it ain't me! ...well, I know I am crazy but at least not that much :wink:

It also goes as far as to take your king with his rook... :roll: :lol:
