solve this 8-puzzle

This quiz is about the 8-puzzle. It is a board with 9 fields. There are 8 tiles with numbers from one to eight. One field is empty. You can slide numbers around the board: But only numbers next to the empty field can be slid into the empty field:

1  2  3
4     5
6  7  8


You can slide the 2, 4, 7 and 5 into the middle.

The start position is this:

1  2  3
4  5  6
7  8


Your task is to give me the algorithm needed to get my puzzle back to the start position.

My puzzle is:

2  8  3
1  5  6
4  7


Hint:

I needed eleven boards to create this pattern, including start and end state.

First solution wins.
