You could have specifically requested Irtx1, but since you have it open, just know that you'll only be able to bet against one person per bet, so if you want to bet more than one person, you'll have to make other bets in the Betting Exchange. And of course you can only go up to your current limit for the total of the remaining bets, which is currently $750, assuming someone takes your current bet. And you obviously already know it's limited to 250 per bet (no idea why we have a limit for fake money
)
