Akichiwake (201)

Instruction:
Shade some cells. Shaded cells can’t touch each other by a side. The remaining white area has to be connected. The white area can't span over two consecutive thick boundaries in a single row or column. The numbers indicate the maximum possible continuous white area within a region. There need not be an area equal to this value; the only restriction is there can be no continuous area larger than the value.
