Please help with above! I can sometimes get fiendish su dokus done, but haven't yet mastered the techniques to finish them all. Having read other threads, I think trying to find 'pairs' is the key, (that's assuming I haven't missed anything glaringly obvious). Any help would be greatly appreciated.
