Once your email address gets onto the internet, you end up on a lot of (chess) mailing lists. Usually I "spam list" most of them, but I still look at them occasionally. One email that arrived recently advertised the $10,000 Nashville Open. Now I'm not suggesting anyone from Australia plays in this event (although feel free to do so), but I found some of the tournament regulations interesting.
While the prize pool is $10,000 only $5,000 is guaranteed (as per USCF prize rules). The prize pool is based on 200 entries, and if there is a shortfall, the prize list can be reduced by the proportion of the shortfall (down to $5,000). Of course if there is more than 200 entries, the organisers keep the profit as a reward for running a good tournament.
Free entry is offered for IM's and GM's, but the entry fee they should have paid ($79) is deducted from any prize money they win. The tournament is run in 5 sections, with a $1400 1st Prize in the top section. Interestingly unrated players can either play in the Open section or the U/1600 - Unrated section. If they play in the open they pay full entry and are eligible for full prizes. If they play in the unrated section they pay $49 entry but are only eligible for half the amount of any advertised prize (ie instead of $800 for first they win $400).
And finally each tournament is a 5 round swiss, although they offer 2 day and 3 day schedules. The 3 day schedule is 1 round Friday, 2 rounds Saturday, 2 Rounds Sunday with a time limit of G/120. If you choose the 2 day schedule, then you play 3 rounds on the Saturday with a time limit of G/75 for rounds 1&2 before joining the 3 day tournament in round 3.
Now these are pretty standard tournament rules for the US, but unusual for Australia. While I don't think there are the numbers in Australian chess to support 3 day/2 day split schedules I think that the rules for unrated players are worth trying, and parsimonious tournament organisers may also find the rules about entry fees for titles players appealing.
