I'm not ambidextrous, but I use both hands equally. Tasks involving fine motor skills are done with my left hand, and tasks involving power are done with my right hand.
So I write lefty and can barely hold a pen righty. Tooth brush lefty, hold a fork lefty, etc.
I throw righty and throw like a girl lefty. Kick righty, open jars righty, etc.
However, for reasons I can't explain, I carry things in my left hand. If you give me three books, I cannot grip them at all with my right hand. I have to carry them lefty, even though my pattern indicates that it should be righty.
In the final seven games of the 2013 season, the Chiefs averaged 34.6 points per game, scored 38 points or more 4 times, and went 2-5. The NFL has ruined the sport.
