More Morra Mayhem

Marc Esserman has demonstrated both in his book Mayhem in the Morra! and in tournament practice that piece sacrifices on d5 can be very strong in the Smith-Morra Gambit (1.e4 c5 2.d4 cxd4 3.c3). In both Esserman-Van Wely, 2011 and Esserman-Sarkar, 2008 he successfully sacrificed a knight on d5, annihilating a GM and an IM in 26 and 16 moves, respectively. In the following game I tried to "be like Marc," but maybe my 10.Nd5!? was premature. The silicon monster thinks that Black is better if he declines the knight with 10...Na5! My opponent made the mistake of accepting it instead and was swiftly dispatched.
