What are the odds of randomly playing the same person twice?

I’m 700 I’ve played someone twice.

I was playing Chess960 once, and kept getting the same person over and over again, who was a much higher-rated than I was, apparently because they were the only person online. I eventually stopped, because I just wanted to play someone else.

I once played bughouse with the same opponent 5 times and we were actually pretty well matched so it was really fun

I got it several times. (And not just in variants).

Rating Level Estimated Chance of Repeat Opponent Notes
<1000 ~0.1% Huge player pool, very rare repeats
1000–1500 ~0.5% Still uncommon unless playing niche formats
1500–1800 ~1–2% More likely, especially in blitz/bullet
1800+ ~5–10% Smaller pool, frequent rematches
2200+ 10%+

High chance of repeats, especially during off-peak hours
