Timothy Taylor's book on Bird's Opening suggests as a main line: 1.f4 d5 2.Nf3 g6 3.e3 Bg7 4.Be2 Nf6 5.0-0 0-0 6.d3 c5. White can also play 2.c4, the Mujannah-Sturm gambit.

The eleven remaining ...
One nutcracker can store as many as 98,000 pine nuts in a single season, and remembering the location of 75% to over 90% of their stash, even when buried in snow more than a metre deep. [7] The memory is also retained for 7–8 months, enabling them to feed their young on seed stored the previous autumn.
The forms that take hazel nuts have thicker bills for cracking their hard shells, with a special ridge on the inside of the bill edge near the base. If the shell is too hard, it holds the nut between its feet and hacks at it with its bill like a chisel. [10] A special adaptation is found in the tongue of the nutcracker.
