Better solutions are available if you have an open slot. Macky's advanced F2L page has some good examples, Jason Baum has some good ones, cubeloop has a lot, but I don't agree with a lot of his algs and Dan Knights has a bunch in a PDF which focuses on cases in [R,U].
Look at all of them, learn and understand them and with enough practice you'll start seeing solutions of your own.

okay i have another question i post in the same topic because i think it doesn't deserve his own
in fact when i solve the cube i always begin with the same face (my bottom face is always the same) ; i wondered if you do that too or if you can do it as fast with any face
so do you think i have to practice with other faces
thx

The best descriptions of these cases I've found are at http://www.jasacube.110mb.com/non_standard_f2l.htm

Can you give some examples? In that way I can make the collection even better.

Hey Dennis,
First off, I love your site and I use it a lot. I think my differences may just be stylistic. It took me a while to understand that Dan Knights' cases were in [R,U], so until then I was always questioning why he'd use a 12 move alg when a 9 move existed. Obviously the 9 move was not in [R,U].
I have to head to work, but just in the first set of adjacent slot examples, in the second case, you have a seven move alg with two double turns on three faces: L' U2 R U2 L U' R', I'd solve it with U R U R' U' R U R', eight moves, but fast, fast. In the third case you solve with, L U' R U L' U2 R' (8 moves), I'd choose U R U' R' U R U' R', still eight moves, but all in [R,U], but it doesn't use the empty slot, which is the purpose of the list.
They're really just stylistic differences and entirely personal preference, I've never actually found any that were wrong. The cases, as solved, are useful for playing with alternative insertions and learning to use the empty slots, but as with everything, you have to pick the algs that suit your style.
Hope you didn't take it as a criticism, I use your site a lot.

No, the more comments I get, the better I can develop the empty slots/stuck pieces pages
