Not rare at all
How rare is 2 brilliant in a row

Randomly looked at a friend's profile and came across a pretty cool string of great/brilliant moves at the end:

Kinda depends on rating tho
I completely agree and I feel like maybe for <1000 maybe a 2% chance 1000+ 5% and 2000+ 10%

hard even if like grandmaster vs 1800
gm vs 100 --> destroys
gm vs 1000 --> still destroys
gm vs 1600-2100 --> has chance of brilliancy or 2
gm vs 2200-2500 --> lower chance of brilliancy

I did two in a recent game, with like 1 move in between:
