Robben missed a penalty following Drogba's clumsy foul on Ribery, and Ivica Olic saw a shotroll agonizingly wide before Gomez smacked a shot into the post.
After the hosts had been pegged back to 1-1 and seen Victor Obinna sent off for a crazy kick out at Sebastian Larsson, Cole bagged the winner with only 10 minutes left - and it was a personal nightmare for Blues keeper Ben Foster, who let the striker's soft shotroll under his hand and trickle over the line.
Hendry, world champion in 1990, 1992-96 and 1999, was on a roll and a sloppy safety shot from Ding let him in again as he knocked in a breathtaking 140 to equal Ronnie O'Sullivan's effort earlier in the week.
