Pencils down! Seriously, you are about to take a quiz. Subject? The principles, attacking patterns, and tactical motifs within the confines of pawn "chains". IM David Pruess has been arming you with knowledge in his first two videos,and now it is time to see whether or not you paid any attention. In the climax of his 3-Part contribution to the Pawn Structure 101 series, David wants you to be ready to think about each and every position and the decisions you might make in a real game. Good luck!
