I don't know. But I did play "Chess Attack" before and enjoyed playing it. Also I think you can ask chess.com support team if they can add this variant into variant.
Are chess.com going to introduce 5x6 chess like Carlsens variant "Chess Attack" ? (Minichess)
Sort:
Is this format fun or good to introduce to kidz that would like to learn or that you want them to get interested in chess? Try to find if you could play 5x6 variants online but cant find anywere to try it.
There are many "minichess" variants but non really seem blow up, does it "mock" the real 8x8 chess because its to "simple"?
