Re: 2014 YEC host cities narrowed to 3 candidates. Where do you want it to be held?
I think the choice should be heavily, but not entirely, determined by the potential market that could be tapped into.
China already has a bunch of tournaments, so doesn't really need the YEC as well. Singapore would be a nice location, but the potential market is negligible.
So my preference would be for Monterrey, on the condition that the organisers can convincingly demonstrate that they can run a tournament like this successfully. If they can't, Singapore would be the best option.
