- Wesley So (2788, world #8) The new kid on the block plans to build an impressive share of second at Wijk aan Zee, showing his talent to fans in America as well as his native Philippines. Well prepared in openings, So strives to milk points from the tiniest of advantages.
- Gata Kamsky (2680, world #63) The champion in four of last five years, Kamsky struggled in 2014 and plays in the twilight of a storied chess career. Indeed, he qualified as a candidate for the world championship in 1993, before four of his fellow competitors were born!
- Sam Shankland (2661, world #84) Born and raised in the East Bay, Shanky learned his moves at the Berkeley Chess School. Gold for his board at the Tromsø Olympiad became his calling card, but hardly his only success. He is aggressive and deadly as white, yet solid as black.

- Sam Sevian (2548) Bay Area chess fans will recall just a few years ago, this precocious kid rubbed elbows at local tournaments. Now the youngest Grandmaster in US history, Sevian has bigger fish to fry. What he may lack in experience, he makes up in energy and enthusiasm.
- Kayden Troff (2544) The strongest chess player from the state of Utah continues to improve. Already a Grandmaster, Troff dominated the 2014 US Junior to earn his invitation.
- Timur Gareev (2599) The free-wheeling and outgoing Grandmaster of blindfold exhibitions brings plenty of flair to Saint Louis. While erratic, he is capably of brilliance in every game.

The concurrent 2015 US Women's Championship features a defending champion aiming to win her fourth straight crown against a 12-player field that welcomes five newcomers. Top rated GM Irina Krush (2477 FIDE) is the overwhelming favorite as she pursues her sixth national title. In the absence of chief rival IM Anna Zatonskih, the next highest rating belongs to IM Nazi Paikidze (2333), a recent immigrant from the country of Georgia. Other challengers include two experienced competitors: IM Rusudan Goletiani (2311) and WGM Tatev Abrahamyan (2301). The youngest invitees are 13-year old WFM Jennifer Yu and 12 year old WIM Annie Wang, a pair of gold medalists at international youth championships last year. A first place award of $20,000 highlights the record $75,000 ladies prize fund.
