an easier step between hard and tough

I can do the hard puzzles without using X wing or more complex/advanced techniques (see http://www.sudokusnake.com/techniques.php for a list that we can use for common terminalogy and classification of techniques). Now i not saying you cannot use more advanced techniques, just that you don't have to.

Tough  ones require the use of many of these techniques, which i am finding difficult to learn them. perhaps if there was a step in between that would only require the use of one or two intermediate techniques, this would make it easier to learn the techniques and then move onto moredifficult puzzles/techniques
