Question about 3 move check draw rule: I have posted five pics. I made sure there is a different square thr king goes on after second check, but yet I could not avoid draw in the bullet chess game.
Three moves draw rule

It’s not moves that repeat. It’s the total position which occurred three times which resulted in a draw. In this game, the same position occurred after moves 16, 18, and 20 for white.

But 16,18, 20 are not successive, right? Isn't that a criteria?
No, in fact the three positions don’t have to occur in consecutive moves.

No, in fact the three positions don’t have to occur in consecutive moves.
Also, it's completely impossible for the same position to occur in consecutive moves.
I have no idea what the OP was thinking.

I am not sure why you say it is impossible. Forgive my naivety as fairly a beginner level Chess enthusiast. As rookies, whenever we played on physical board, we used the three move draw rule to force a draw and it usually was consecutive moves on two or three squares, hence the confusion.

The same move can't be repeated immediately, because now your piece is on a new square. The closest you can get is to make the same move every second move, going back and forth. And that's what you did in the game, you played Qf4+, 3 times in a row.
But anyway, it's not the moves that matter, the rule is about the repeating of the position. As explained in the article linked by Manekapa.
And no, it doesn't have to include check. Perpetual check is just a special case.
