The question answers itself. Forcing is forcing. Normally partner has less than 11 or 12, but in some styles, can have more. Regardless, you must bid (I suppose it would be OK to pass when playing against a BOT in a robot tournament, since you are only hurting yourself.) With the example hand (you may have a partnership agreement for this specific size/ shape) you either rebid 2C or 2H. There are reasonable arguments for either alternative.
