North had a lead of just 1 run when AM Makda dropped an easy chance at third man off a top edge. West would have had a good chance at that time. Instead of a 1st innings lead of just 1 run therefore, North landed up with 66 runs lead. That dampened the morale of West and they collapsed in their second essay.
There were other dropped catches also in the match, but this one can directly be linked to West loosing the match........
