Calvin Shane Anderson

Calvin Shane Anderson was born in Yukon, Oklahoma, and now resides in Las Vegas, Nevada. He discovered poker at age 18, depositing small amounts on PokerStars and initially struggling. Determined to improve, he studied the game and gravitated toward mixed games, inspired by players like Daniel Negreanu and Phil Ivey. Under the screen name "Stammdogg," Anderson became a force in online poker, eventually reaching the #1 spot in global rankings. He amassed ten titles in PokerStars' Spring Championship of Online Poker (SCOOP), a record at the time that was later surpassed by Benny Glaser.

Anderson's first World Series of Poker (WSOP) bracelet came in 2014, winning the $1,500 Seven Card Stud Hi/Lo event. He followed that with a victory in the $10,000 Razz Championship in 2018. During the 2023 WSOP Online, he captured two bracelets: one in Pot Limit Omaha and another in No Limit Hold'em. In 2024, he added a fifth bracelet by winning the $10,000 Eight Game Mix event. By 2026, Anderson had increased his bracelet count to seven, including two more won that summer, making him one of only two players with five bracelets since 2023 (alongside Nick Schulman). His bracelets span six different variants, showcasing his all-around mastery.

Anderson's largest live cash came in December 2023 at the WPT Prime Championship at Wynn Las Vegas. He outlasted a field of 10,516 entries to win $1,386,280, the biggest score of his career. This victory cemented his transition from online dominance to live tournament stardom.

Anderson is known for a technical, fearless, and versatile style. While many modern players specialize, he excels across all poker variants, from No-Limit Hold'em to obscure mixed games. His strategy emphasizes game flow and psychological reads, often exploiting opponents who rely heavily on solvers. He is described as dedicated, often arriving early and leaving late. Off the felt, Anderson is analytical and solves a Rubik's Cube behind his back, reflecting his methodical mind.

Despite his achievements, Anderson keeps a low profile, rarely giving interviews and avoiding the spotlight. He has never actively sought sponsorships or worn patches, preferring to focus on the game. His peers respect his discipline and humility. As of 2026, he is a contender for WSOP Player of the Year, though he acknowledges Alex Foxen's lead. Anderson's combined live and online earnings, including a net worth estimated over $12 million, place him among the elite. His Hendon Mob record shows over 114 WSOP cashes, 23 final tables, and total live earnings exceeding $7.7 million. He stands as a quiet giant in poker, letting results speak for themselves.

Anderson's online career under the screen name "Stammdogg" was historic. He amassed ten titles in PokerStars' Spring Championship of Online Poker (SCOOP), a record at the time that was later surpassed by Benny Glaser. This achievement, along with his #1 global ranking, cemented him as one of the most formidable online players in history. However, Anderson has not played on PokerStars for the past eight years, transitioning his focus to live tournaments.

By the 2026 WSOP, Anderson had won two additional bracelets, bringing his total to seven. This made him one of only two players (alongside Nick Schulman) to have won five bracelets since 2023. His 2026 campaign included a deep run in the $50,000 Poker Players Championship and a strong bid for WSOP Player of the Year, though he trailed Alex Foxen. Anderson's seven bracelets span six different variants, showcasing his unmatched versatility.

Despite his elite results, Anderson remains one of the least flamboyant top pros. He avoids vlogging, rarely gives interviews, and has never actively pursued sponsorship deals. He attributes this to his non-controversial and unassuming nature. Off the felt, his analytical mind is exemplified by his ability to solve a Rubik's Cube behind his back, mirroring the methodical approach he applies to poker. This understated personality has kept him out of the mainstream spotlight, but his peers hold him in high regard.
