Hannibal game from 8CPU tourney

[jdart]

from Graham's tournament http://talkchess.com/forum/viewtopic.ph ... 06&t=46385.

It looks like from the scores Hannibal hallucinated that it was winning after h7+:

[D] r3r1k1/pp1bp2P/3p1p2/q1pPn1p1/2P1P3/2N5/PP2B1PQ/R3K2R b KQ - 0 20

It must have something wrong to get scores that high.

It looks like from the scores Hannibal hallucinated that it was winning after h7+:

Excellent, that is the first time I've seen that word associated with an engine

It actually did Ray

We will probably hear that the chess engine was completely delusional in this or that position.....

(Perhaps there should be a sticky in each forum advertising the new <pgn> tag? And it might get more acceptance if it made use of the larger gif images used by the <D> diagrams.)

+1 !

If there is one thing missing in the new pgn replay, it must be the graphical display. The regular diagrams look so much better, and provide a way to highlight a specific position.

It looks like from the scores Hannibal hallucinated that it was winning after h7+:

[D] r3r1k1/pp1bp2P/3p1p2/q1pPn1p1/2P1P3/2N5/PP2B1PQ/R3K2R b KQ - 0 20

It must have something wrong to get scores that high.

Thanks for the report! Unlike a couple of the previous error reports, I think we actually noticed and fixed this before releasing Hannibal1.3. Here is what I get from this position:

Glad it is apparently fixed. FYI here is another game where the 20121202 version mis-behaved (34. f6):
