According To the tutor black can hold white in perpetual check BUT if whites king moves to G1 and blacks queen moves to C1 what prevents whites queen on C8 from taking it?
Perpetual check

According To the tutor black can hold white in perpetual check BUT if whites king moves to G1 and blacks queen moves to C1 what prevents whites queen on C8 from taking it?
Yes, white can take the queen. That is correct.
However, after white takes that queen, it is stalemate, so again a draw.
Why stalemate? Well, after Qxc1, it is not a check, so let's try to find a single move by black. h4, g7 and f6 pawns are blocked, can't move, g6 knight is pinned to the king, so it can't move either. Finally, king can't move because h8 and g8 are off limits because of the queen on b8, and h6 is off limits because there is a white queen on c1 if white played Qxc1.
Therefore if white takes the queen it is a draw by stalemate, so white doesn't take the queen, so black can go back and forth with his own queen and have a perpetual check.
For the similar reason white does not take the queen while it is on f4.
The last thing white can do in this position is g3 to block the check instead of moving the king. But after Qxf2+, there will again be perpetual check (1. ...Qxf2+ 2. Kh1 Qf1+ 3.Kh2 Qf2+ etc. ).

at this point i just give up chess, already, yes, i don't want to play with you anymore.
Whey stalemate? and what is the difference from a draw and remis?

me neither, i think that's good, just learning the figures movement, watch out not to loose more figures then your opponent, or at least not without a plan for that like me, because i allways end up loosing recently. People rather take everything from my figures, rather then give me sometimes a pawn or bishop or knight.
It was a bad day for me and therefore the world. Tragic.
