Partial edge control
From Speedsolving.com Wiki
Orienting the LL edges during F2L, by careful selection of F2L block insertion algs. As an example, perform F R' F' R' on a 3x3. If you insert the pair with U R U' R', two LL edges are misorientated. If you instead insert it with R' F R F' (also known as the sledgehammer), all the edges are orientated. You can use this to avoid the dot OLL cases.
