Hi Orlando

Yes the Nd3 move is a forced win (not a coulda/shoulda/woulda). Sjeng was not able to find it unfortunately. Other Sjeng versions do find the move but the
beta used in the tournament did not find it. It has to do with evaluation things and i am sure Gian Carlo is already on it...

What is very interesting Orlando (and what nobody will notice nor admit because they all just look result or dont care):

Sjeng completely overplayed, more like stomped hiarcs down positionally. Only one side played in the midgame. Sjeng came out of the opening rather bad but
consolidated quickly and started to play forward. That active playstyle and positional powerplay is something that recent sjeng versions learned. Unfortunately
(as it often is with beta versions) it could not find the "sac" move...

Nevertheless i am very happy about the game (and so was Gian Carlo) because we both prefer engines that actually DO something. It is quite easy to pull the
"sit and wait for enemies mistakes" thing but that is not chess to us 

Cheers
