Do you see an actual chess board, or a two-dimensional one like the ones on chess.com?
Oh my! I can see in 3D. Chess board and chess pieces.
Also, I can bring up, from memory, the 3D look of Chess Titans, as well as the look of a chess.com Live Chess game in 2D. This is very cool. Who needs a chess board?
I started playing chess seriously a few years ago playing Chess Titans. It is quite visual, with squares that light up to let you know where pieces can go, along with 3D like pieces and board. This Chess Titan look has really burned into my brain. I'm going to play with that program some more, for visualization exercises.
It's an invalid FEN code (two of your ranks don't have 8 squares) but it works for the diagram somehow.
Are you sure? I counted 64 squares. I also counted each rank and each file separately in case of some optical illusion. The corner squares are also the correct color. It all seems to check out just fine.
"r1bq3/1pp5/p1p5/8/8/8/8/7 w - - 0 1"
Only 7 squares for each highlighted rank in the FEN.
I see. It sounds like it is necessary to create an invalid FEN code to create a diagram of 64 squares without kings.
