EI wanted to know if there is any website or PDF about the screw method for advanced square1,Because I thought of intermediate and advanced variants for the screw method.
I'm pretty sure that Roux and Screw is just the old name of the method called Lin (which I use). You should be able to find more resources about the method with that name.
