Alan Lasser's Game of the Week

  Check out the position after move twenty-nine;  talk about unbalanced material, White’s four pieces are completely different from Black’s three pieces, throw in a couple of extra pawns and try to figure it out.  The computers at the TCEC 10 are certain the position is equal at all times.
