One way to do well in a tournament like this is to apparently enter many times - undoubtedly you will eventually have played nearly all the boards before.

In the most recent Survivor:

ivasilev4 77.43 1

ivasilev1 72.67 12

ivasilev2 62.97 630

ivasilev 60.65 1134

ivasilev5 59.92 1373

ivasilev3 48.55 7027

(Ivasilev1 through Ivasilev20 are registered users)

Nice piece of detective work

(And damn stupid of the perp to make it that obvious)

It's a free for fun two day event with no prizes. There is some security but no excessive IP check and lots of deals like in the pay ones. It's meant to be training people for multi-day events.

We'll warn this player to stop entering with multiple aliases.

Interesting, are the results normally distributed or was there any systematic improvement.

It's hard to reach any firm conclusion about the distribution with only six data points, however, distribution is pretty much single peaked...

A priori, I'd expect that score improve as the penetration increases, however, it's hard to tell what's what without more information (for example, can we safely assume that the player is using ivasilev for their first entry, ivasilev1 for their second...)

Not a recommended practice but Ivasilev seems to be making a genuine attempt to learn by trial and error, with no attempt at concealment of his modus operandi

Come on guys, there is an obvious reason to enter with several aliases - the tournament is free, and you can play it once per account.

I don't know how many boards this tournament uses - maybe you would have seen one on average the 6th time you play it?

Last I looked at these things (which was a couple years back) BBO was only using 960 boards for large / relatively prestigious events like the ACBL Online National events.
