I never knew that Winnie the Pooh and Jessica Alba with a stripper outfit on could make friends.
LOL! There's a sentence you won't hear often! I won't even go near the combination of Jessica and 'teabag'...
Anyway, getting back to Koby: under those circumstances with 2 players I can imagine the deadlock, if she didn't have enough corn to buy a shirt at the market (or a spare resource to sell). She could move out and in of the market to bring the price of shirts down one by one, but you could easily undo that on your every turn (if you don't mind sleeping on the couch of course )
