I’ve seen some other strats that have worked, but they’re really gimmicky.
Kill USA First (super gimmicky! Relies on the US not seeing it, and essentially leaving Washington DC virtually defenseless)
Sea Lion (far less gimmicky). Relies on the UK not defending well enough or over extending while Germany drops a transport fleet. Not sure I like this one, the expenditure is so freaking huge that I have a hard time seeing how Russia doesn’t eventually take Berlin…
Just a couple ideas. I didn’t say good ideas, just ideas. As I said, both are gimmicky really, but if you can get away with it…why not? (My Kill Japan First strategy in Anniversary Edition was gimmicky, but most of the players had never seen it and were pretty darn hard pressed to figure out how to counter it after they did see what was happening. Likewise, my Power Russia strategy in 2nd Edition classic allowing the US to power on Japan…again, gimmicky, but rare enough people need time to figure out how to counter it.)
