Miss? Is that a new thing?

I played against the new Chiefs bot and I saw this. What is a miss? Did it replace a missed win? If it did, what is the purpose of it?

It replaces Missed Win but also includes other types of misses as well.

• New Miss Classification - Sometimes a move is bad not because something went horribly wrong with your own position, but because you failed to punish your opponent’s bad move. For example: you’re in an even game, your opponent gives you the opportunity to fork and win a piece, but you just make a normal continuing move as if nothing happened. These cases will be covered by a new classification called Miss, which will be denoted with a Ø glyph.

Thank you so much

it think the symbol should still be that old one but "miss" works

That's an onimous glyph. But I guess a smiley face just doesn't work.

Probably lagging!

Have you seen my Mrs Mr Jones? Do you know what it's like on the outside?
