Make sure when you play Germany to Gas the french real good. You got a few turns before they can gas you and you get gas masks sooner.
Man i love sending in gas canisters against the allies.
Turn 1 is a good turn to launch the German fleet, use your zeppelins and always take the Schlieffen Plan option.
Try to kill one front then the other. If you try both you may fail. You can also just grab some french and go after Russia. Latter in the game Russia will fall by itself, but to remove it early is huge.
Don’t let the Ottomans get too weak. If they go you lose the whole front because they cut the board in half.
