Military ideas such as those in the "Art of War" can also be applied to poker. In my (non-bridge non-poker) blog entry on writer Van Creveld I note the military success elements of logistics, intelligence, convergence and sacrifice. These can also be applied to poker.

Logistics - Have sufficien bankroll to keep playing, to keep firing away
Intelligence - Who can fold, and who will keep on calling
Convergence - Picking the right spot to get all the chips in
Sacrifice - Limp in sometimes with a great hand- sacrifice a likely small gain for a possible big gain
