@ Similar to AC 3-tier advance reservation booking , you can book for Chair Car class tickets also.
@ In your case, chances for confirmation are good. Check the progress in due course and then may decide for taking a chance in Tatkal booking which will open on 11.6.2010 . You can straight way take chance in Tatkal, and if get confirmed ticket in...
