Long time ago I landed glider with broken rudder. Rudder cable broke during stopping spin rotation in aerobatic flight on 3000 feet, decided not to bail out to see if flying and landing is possible and to save the glider. Flying with "hardover rudder" (full deflection) was interesting experience. Broken rudder cable will cause a severe yaw and roll with the resulting sideslip. Glider keeps turning, spiraling or circling in one direction (of unbroken cable) weather you like it or not it wants to spin or spiral all the time. You need much higher speed about 140 km/h or more, or whatever it takes to control it to stop turning and to go into steep sideslip to fly straight with 30-50 degree of bank. Forget your legs, you don’t need rudder pedals any more. High speed and ailerons are your only friends. Keep your speed high because glider wants to spiral and stall at slower speeds. I landed that "sucker" perfectly by flying high speed in deep "grave" sideslip all the way to the ground to middle of airport leveling wings moment before touchdown with full air brakes. I'm probably one of very few pilots that pulled this off with success, and I was 22 at that time, had 130 flying hours in 220 flights.
I remember that in situation like this you think very fast, you even have time to think that a few months earlier there was the same type of accident in other part of the country and pilot bailed out and glider went through the roof of the house. Also tighten your belts and keep your feet off rudder pedals, just in case. Keep your speed high, wings level, expect severe yaw, circles become wider, it takes time before you can fly straight with one wing low. If you slow down glider will start turning again so keep your speed up to go straight. This flight was 9 minutes including 6 minutes tow to 3300 feet when several other “normal” aerobatic flights were 16 minutes.

For all the rest of us who might not be able to "land land that sucker perfectly" I would suggest giving it to the insurance company and bailing out.
