This 2 forwards versus 1 defender drill is a great all around drill. The Inside Soccer website has a "training programs" section that really helps coaches get a full well-rounded practice session together. Click on this green Inside Soccer link to take a look at the 2v1 choice drill. This is a short, barely over 2-minute video that demonstrates a drill that should help your players develop quick decision making, passing, and defending skills.
Clicking on the green "Inside Soccer" link above should take you directly to the 2v1choice training video. If it does not, or if you would just rather look through the entire training programs section: you can click on the title of this post to go to the Inside Soccer Training videos. I also provide a link to the Inside Soccer website in the column on the right of this page.
