Vinnie Mauro of USSF Soccer has been distributing an on-going series of game situations.
He polls those on his distribution list and posts the correct answer.

These situations are usually applicable to USSF, college and high school.

With Vinnie's permission,  I have reproduced some of them here. 

If you are registered with USSF and would like to be directly on distribution,
