As the Chess Legend persona for this profile, Geller favors aggressive, high-tension chess, frequently reaching for the [Open Sicilian](/resources/openings/open-sicilian) as White to seize central control early. The bot's decisions reflect this curated repertoire rather than any specific historical game record, and its 3120 rating means it plays with near-flawless technical accuracy across all phases.
