All Rubik's cube positions can be solved in 20 moves or less; http://www.cube20.org/
What's one such position that requires 19 moves to solve, please give the faces, and the moves to solve.
Given any position you know that has 20 moves (like the Superflip) just do one move towards the solution and you have a position that requires 19 moves.
Below sequence movement from a solved cube will make the position solvable in 19 moves
F U' F2 D' B U R' F' L D' R' U' L U B' D2 R' F U2
And the solution would be
Step 1: U2
Step 2: F'
Step 3: R
Step 4: D2
Step 5: B
Step 6: U'
Step 7: L'
Step 8: U
Step 9: R
