Don is correct, KORD has undergone a lot of MAJOR RW changes lately!  I tell most Pilots that if you don't like the Runway/Taxiway configuration at O'Hare, just wait 10 minutes and it will change!  The RW you speak of is either 10L, 10, or 9R depending on your scenery.

All of our ZAU Controllers are trained to remember that there are about 17 scenery packages out there, and to TRY and make sure they know what the Pilot is seeing.

If EVER in doubt, please confirm all RW assignments wit ATC and we'll get you to the right spot of turf to land!
