One I can tell you is let say you have in a square(3x3) 2 possibilties for the number 5.. if those possibilities are on the same line.. let say horizontaly.. than you know its impossible that the number 5 be anywhere else on the "big" horizontal line .. So you can work by elimination..

I don't practice that much. It's all logic.
Don't start filling out the squares where half or most slots are open. That means that the adjacent big squares are mostly empty. Which means more combinations for you in the square you are working in.
If you start filling out the big squares that are mostly empty, it means that the adjacent big squares has numbers in it, which means less combinations in the square you are working in.
Hope you get what I mean
