I also got Rg8 when I analyzed the game manually with Rebel. I guess that you need to play manually the moves of the game in order to get Rg8. I did not try the position without the game. My point was not about the time that Rebel needs to avoid it but about the fact that this move should never be condsidered as best. My point is that it is possible to learn about Rebel's problems from looking at the ssdf games. Uri
