Juan Sebastian Fonseca Chaves, a Colombian poker professional, has built a reputation primarily through online poker tournaments. His consistent performance in major online series has contributed significantly to his career earnings, which exceed $1.27 million. While details of his early career are sparse, his online results have established him as a formidable player in the digital arena, where he has reached numerous final tables and won several high-stakes events.

Fonseca's most notable live achievement came in February 2025 at the BSOP Costa do Sauípe in Brazil. He won the R$ 15,000 Grand High Roller, a tournament that attracted 172 entries. The victory earned him R$ 503,000 (approximately $90,000 USD) and pushed his live tournament earnings past the US$ 800,000 mark, according to the Hendon Mob database. This win was particularly significant as it marked the second major victory by a Colombian player at the event, following Carlos Serrano's win in the 2-Day High Roller just days earlier.

The final table was stacked with talent, including Serrano, who finished sixth. Fonseca entered heads-up play against Brazil's Gabriel Schroeder with a 2-to-1 chip advantage. The duel was closely contested, with Schroeder briefly taking the lead. In the final hand, the board read 7-6-2-J-6. Schroeder moved all-in and was called. Schroeder showed 8-5, while Fonseca held 7-5, giving Fonseca two pair (sevens and sixes) to secure the title. Schroeder took home R$ 340,810 as runner-up.

As an online-focused player, Fonseca Chaves employs a solid yet aggressive style. He leverages positional advantages and data analysis to make informed decisions, a skill honed through extensive online play. He is particularly adept in deep-stacked phases, where he flexibly adjusts his strategy based on opponents' tendencies.

Following his BSOP victory, Fonseca has continued to compete in major live events. His performance in Brazil highlighted his capability to compete against top-tier international players.
