Can some members help with how to convert material in this problem? http://www.chess.com/computer-workout/server/extra-bishop-kings-indian

Can anyone give any advice?

Hey buddy, don't worry about closed positions, like the KID at your level! You should be at least at my rating before you worry about playing those types of positions. I'd probably stick to the tactics trainer for a while if i were you. Often members post analysis of the tactics in the comments also. This type of learning wil benefit you much more than "how to convert an advantage in the kings indian! (which is a defense even masters can have dificulty with)

That's my advice. Hah

Oh and the "Study Plan" feature under the Learn tab is great also.
