Center turned
Step 1 / 4
U: Two layers around the top corner: turns clockwise (looking at the top corner)
The back center is turned, with yellow on the right face. Both yellow edges are on the front face's top edges.
U moves yellow-blue to the back and yellow-red to the left. L then R' carry yellow-red past the front bottom edge into the bottom right slot. Both edges now match the back center, so B' turns the whole V to put yellow down.
