Interesting. A large part of micro-Max' rating is definitely due to the factthat it is a very stubborn defender, that fights all it can to prevent the opponent from advancing his Pawns.

Actually,taking a closer look at the game again,it looks like I've missed several lethal shots against this little beast....

Won't be that lucky with the black pieces
I promise regards,
