I may have one or two.

However, nowadays, there are so many ways to cheat in a Chess tournament, you literally have to hand over every single little electronic you have on you (turned-off phones will also have to be turned in) in order to attend most events. And people can deny all they want, but given how long players typically have to think for their moves, it is incredibly easy to get a CPU to figure out what you should be doing within that timeframe. ESPECIALLY when the tournament is happening online.

Of course, you might not care about this. Just consider it a warning for what is likely to arise.
