u/SockTaters

Set up the board by clicking any piece then click the square you want to move it to. The first piece must be clicked twice. Capturing pieces works similarly.

different strategy, draw the board on the first frame, pieces on the rest
u/FireFly

ohhh that is good, was too tunnelled in on the setups I'd tried.. good job 🎉
u/TGY

now comes the real challenge "e2-e4"
u/tomxor

fillText Y=i==52?Y-T:Y+T, but can't animate with this method. Don't think it's going to be possible in 140 ether.
u/DataMeta

ugh yes. so satisfying
u/sigveseb

very good, but the king and queen on one side are reversed!

#chess board

u/FireFly

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 :)
u/tomxor

I have an imperfect 142
u/Agnes

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'"

ohh good one, didn't know about the font-family name trick
u/TGY

now we need to combine 2 dweets into single XD
u/DataMeta

fit them together with compression, but would be more interesting to jam it into 140 :)
u/FireFly

I can do a full chess board in 151c currently, but it *would* be really satisfying to fit it into the 140c without compression tricks indeed
