"[L]ead low from dummy and put in the ten whether East follows suit or shows out."

As Reese wrote, this should be worked out at the table. However, it is much easier to do so when you've seen it before. (By the way, you can also go up with the ace on the first round once East has shown out. Then lead back a low heart toward the K-8. The point is to start with the deuce.)
