Am I crazy or the game just made me lose for no reason ?

So I got into that position, the last move was me moving my h rook to g6 to pin the knight because I knew that queen takes f7 was going to be played, when I saw him actually moves his queen to f7 I was happy at first but then I saw that the game wouldn't let me play king takes queen f7... Is that a rule that I don't know ? Because for me the knight is not really protecting his queen because of the pin... Someone tell me the truth pls ! thank you

You cant make a King move that puts you in check. Thats an illegal move.

So the pin does nothing in this position ? Because I'm thinking King takes queen then knight cannot takes back

The King cannot take because it would be on check. Its the same as when castling. You cannot castle into check or through check.

If to think so: If you take their queen with your king, then why would white take your king? Because of the pin? But they take your king first, who cares? That's why, to avoid all this tricky stuff, the rule says, that you simply can't move your king into a check, no matter if a piece is pinned or not

If you feel that you should be able to ignore the Knight, then why can't HE ignore your Rook.

Look at it this way: If chess were played out right to the capture of the enemy King, whose King would die first? Yours, or his?

Ok guys I got it, that makes a lot of sense, thank you all for explanation

I think I got this misconception because we never litteraly takes the king in chess we just end on checkmate and never takes king so I didn't even think of knight takes king, I just saw pin = cannot move or I check his king
