Sounds interesting and promising, but most of the most active 1v1 players are signed to webdip's 1v1 tourneys - this is why I step back _at_the_moment_, at least.

I say it is promising because we could open variant specific tournaments for each of all 1v1 balanced maps - three come to my mind: Cold War, America Civil War and Frankland vs Juggernaugt. Of course, FvA and GvI tourneys would be welcome, as well, but, as I wrote above, we can find lots of these in webdip already...

I am not that certain about the unbalance of E*vT and GvR, though from my own experience I'd say England does have a winner set of early game moves, while for the latter the 76.5% unbalance is obvious from 428 recorded games statistics.

Finally, I'd avoid tourneys for the symetric maps, such as Duo and Lepanto, but I could be convinced of the contrary.
