I’m surprised that grown ups can still be confused by this.
While of course Hashem can do the impossible, these examples arent impossible they are meaningless.
while we say it is impossible to divide by zero, thats not because it is too difficult for mere mortals Rather its that it is meaningless. Can he create an object that is blackwhite or a circle with 4 corners (im not reffering to an optical illusion). ITs not that He cant, its that there is no such thing. By definition if it has corners it isnt a circle. This isnt a limitation on Him r”l it is a limitation on us and our language.
chess has rules if He does some other move that isnt allowed by the game that it isnt chess. So no He cant win in one move. Not because He is limited but because the game is.
(Though what might prove me wrong is the Aron not taking up space, though I’m not clear on what this means. The classic example is if measure from side of Aron to each side of mishkan each measured 5 amos although the aron was 2.5 amos long and the mishkan was 10 amos. What if I take a tape measures lay it along the length of the Kodesh kedoshim it reads 10 amos. I take another put it from aron to wall it reads 5 amos are those amos different sizes? is this an illusion or is it something that is meaningless and yet Hashem can do it)
