Hide and seek is always fun. I play soccer with Cosworth as well.
I have a flat soccer ball (is there anything better?). The idea is that Cosworth is the goalie and that I score by getting the ball past him such that it bounces twice.
It's actually really tricky. He's really, really, quick side to side so even the fake kick with one foot, kick behind the heal with the other basically never works anymore. Really the only good way is over the top... But, if the kick is too high he will turn, run, and catch it out of the air. If it's too low, he'll snag it on the way up. Even if it is just right, he'll get it on the first bounce... You have to get it close enough that he goes for it on the up take, misses, and has to turn and chase, and EVEN then he still gets it on the first bounce 90% of the time.
