opponent moved too fast
It was an end game in speed chess. He had 7 seconds left and still have 5 left after advancing two pawns with king interference then mating me with two queens. There is absolutely no way he could move that fast with predicting my moves.
There, he spent 3 seconds moving. He had to squeeze his premoves into 1.5-1.6 seconds for most of my moves. I could hardly move in 1.5 seconds. I think there is some funny business if my opponent could 17 moves in 3 seconds. I don't care about the win. I just play speed chess for experimentation. I'm just saying it looks kinda bad.

Almost all those moves were pawn premoves and didn't take really any thought or much worry about where you moved. If you notice, your opponent took a little extra time on move 52 when he wasn't sure where you would move your king. Then other than move 55, it was just pawn and connected queens premoves.
I have identified the game only. When your opponent uses premoves, he (she if the person is a female) can input his/her moves in advance while waiting for you to take a move. If the move being input is legal after your move has been made, the system will automatically play out that move for him/her, and only 0.1 second will be deducted for that move.
In the game, you had a king remaining and far away from the h-pawn promotion, so obviously all your king moves would not affect the pawn's path, and he/she could premove all the moves leading to promotion safely since all the moves played were clearly legal. Clearly the moves could be played regardless of where your king went, so there was no need for your opponent to predict your moves at all; the premoves would work in most circumstances.. The same goes for the g-pawn promotion, where your king clearly did not affect the pawn's path to promotion at all. However, your opponent must have premoved Qh3 without expecting you to play the worst possible move Kf3 which failed to the standard queen shuffling mate in the game.
