I'm curious, what's a good challenge to have active at the micros to build credits?
Pretty much any of the cash game ones really, depending on whether you want to actually use them to work on your game or whether you just want the credits.
I've got Phil Gordon's five common hold 'em leaks one running at the moment and the tasks are hilariously easy. I completed all of them while two tabling in about 90 minutes this afternoon.
I like Bill Edler's power of position one too, but you've gotta take a lot more risks to complete the tasks in that one - it wants you to do things like floating with nothing or win three times running from the button. It's plenty doable, but might carry a bit more risk than the hold 'em leaks one.
Haven't tried many of the other cash game ones yet.
