In a medium sized bowl combine the eggs, sugar, butter, syrup, vanilla, and Jack Daniel's whiskey. Mix well. Sprinkle the chocolate chips over the bottom of the unbaked pie shell. Cover the chips with pecan halves starting around the outside edge and working your way in towards the center, with the pecans. Pour the filling over the chips and pecans. Pecans will rise to the top during baking. If they flip over after pouring in the filling, turn them so they are turned the same way and will look pretty. (as my ggmother used to say) Bake at 375 degrees for 35-40 minutes, or until a knife inserted about halfway from the center to the edge comes out clean. You may want to cover the pie crust edge with aluminum foil or a ring to keep from browning too much.
