"Second in the popularity stakes, inexplicably, is the Austrian Attack: moves as above but with F(Sev)—Rum. The favour shown to this opening convinces me that 16.9 per cent of Diplomacy players are insane... Playing this opening is like playing Russian roulette with all six chambers loaded and hoping the one that comes up will be a dud shell. Not recommended."
