Thus the basic strategy for fighting the King. You "bait" him into playing his cards in such a way that the ones with the same numbers (like 6s and 7s) or other pairs of numbers you can easily Plus are ready to be taken advantage of.
The "standard" method I've seen (and used, it works okay for the most part, but only when you're first and he won't always play by the rules) is to put Dodo in bottom right, then Mandragora in the top left, Couerl in bottom left, and Sabotender in top right. If he's playing along, he will have placed his cards in such a way that leaves the middle free (usually the last card dropped is Urianger, but sometimes it's Bahamut?). Dropping the Bomb (hee) in the last slot will cause a chain-Plus combo that will net you the win.
And, once you actually understand how Plus works, you can start trying to adapt and using the numerous same-number and minor-number-variations of the starter cards to enact Pluses when he doesn't want to play along. I don't win all the time, but figuring out how Plus actually worked helped me pull out more victories against him.
