Remember to put a space in the place of your peice you removed otherwise the board just gets more disoriented.
There must be a way to keep all the squares locked into place only moving the letters,meaning it's a set grid which wont make a difference when moving the peices.
I tried two things that works in a browser but not on tapa. One is using the teletype tag (when replying in browser theres an option for it). Two, is to use the courier font which all characters are the same size. But these option dont work in tapatalk. So I'm just not going to use either one and changed some of my underscores to periods to try to make it even. I also added a period to your rooks. We'll see if it works out.
