RE: Lorentz.
Im not sure if 5466 is human or not but I was able to defeat 5466 in the current amazons championship. 5466 does have the highest amazons rating by a big margin however.

5466 has been around much longer than the NN bots. I’m 99.9% sure he is very much human!

So...basically , the better the ELO greater de chances to win...
Do you use an excel platform for doing this predictions? I’m trying to understand what is this all about. There is too much stuff in internet...about stocks, investing, horse racing. It is very confusing haha.

Your probability of winning any game is in theory 1 / (1 + 10^((your rating – opponent’s rating) / 400)). So, using your favorite programming language, you define all the matches within a tournament and generate the outcome at random using this formula. Do this thousands of times and count how many times each player won the tournament.

I got it.
what would be the theory for a race competition?where every player is against everyone and not 1vs1
thanks

Force majeure, I think your predictions concerned the hex championships (not havannah)?

I will not be playing any Havannah soon haha!
Is there really a “400” in that equation???
Interesting :)

It corresponds to a probability of 1/11 for a difference of 400 elo, or the reverse:

Heh Elo has been “improved” with Glicko, but the graph of rating difference to odds of winning remains about the same. Glicko is more complicated, assigning two numbers to each player: rating and ratings deviation or how accurate your rating is, based on how much you have been playing lately. Then there is Glicko2, which adds a 3rd value: volatility. It could be argued that the simplicity of Elo is preferable, especially with a relatively small group like us.
Arek you should definitely play more Havannah and more Twixt.
