dilation is a very simple (while not perfect) way to do that:

im = im2double(rgb2gray(imread('board.png')));
imd = imdilate(im,strel('diamond',1));
res = im - imd;
res = res - min(res(:)); res = res./max(res);
imshow(res)

enter image description here you may also apply some thresholding afterwards.
