There must be some symbolism around that chess board from the fire department.
Initial board -

- we clearly see the king is cornered. Most likely representing Walt being cornered with very few options available. The king is white. Yo, mr. White?
King is moved -

- the white king makes a move. Probably a last spark from Walt to get out of this situation.
Pieces representation:
- the black side has 6 pieces. The black king may be uncle Jack and the other 5 pieces his goons? We know that at the shootout there was uncle Jack, Todd and 4 more guys.
- the white peons may represent Skylar and Jr.? We see the king making a move towards them. Representing Walt's call to Skyler maybe?
- that leaves us the white knight. We see that he is on the other side of the board, near the black pieces. Could it be Jesse? We know that Jesse is being kept by Todd.
Thoughts?
