I've stared at this for too long... don't think I can get it below 146 decompressed (with Z inlined). Would be rad if we could squeeze those last characters out though and get it down to 140 without compression :)

I have an imperfect 142

This is 145 but I don't remember if the new indexing is actually shorter or not than yours: for(i=w=128;i--;x.fillStyle=R(i%2?x.fillRect(X=i%16*64,Y=i*8&-w,m=X+Y&w,m)|w:x.fillText('♜♞♝♚♛♝♞♜♟ '[Y++%7?++Y%5?9:8:i/2%8],X,Y+w)))x.font="4cm'"
