Moder Helpfare 2, Modern Pawnfare 2 (A chesstastic game!)

I'm playing Modern Warfare 2 and i keep getting up to 7 or 8 kills, depending on whether I have Hardline Pro on or not, and not getting a Stealth Bomber if you can help follow me and tell me how. On the other hand Modern Pawnfare 2 is a chess game type consisting of Pawns that move like Queens and where Blacks go first.
