right here, after entering in all the moves, some programs switch to Rc7

Also, Nd3 looks like it will also draw for black.
So I believe screamer is doing fine here.
When LG faltered in the game it must have thought there was still a draw to be
had. I recall Uri mentioning this about LG, that it finds draws sometimes that
do not exist. Of course on the occasions when LG is correct it looks brilliant.
