Error in chess logic
It's not a bug, computer is just trying to "prolong" the game in hopes for you to make a blunder ( maybe moving the king away in a panic from the check or something) but at that point you had mate in 5 and out of all the moves that computer had were the sacrifices of queen and bishop just to prolong the inevitable checkmate. GGs
Chess engine said "this is the way to win a queen", and then when "show moves" button is pushed, white queen goes to G7 which is undefended position, and gets eaten by black king, so that is completely wrong.
Is this some bug?
