This is what Crafty (modified) thinks in this position.  Before this it liked
the move Rh5, and it never thought about e8=Q.

                    10->   5:14  -0.12   1. g4=R
                    11     6:55     ++   1. g4!!
                    11->   9:06   0.27   1. g4=R

I don't know where "=R" is coming from, but I occasionally get strange output
like this...Any ideas Bob?

This is from a PII-300.
