A portrait in contradictions: Tonijo loves tactical melees but often finishes games in long endgames. Highlights from his statistical profile:

Tonijo's repertoire is wide but shows clear favorites. He plays aggressive setups as White and reliable, sometimes rare, defenses as Black:
- As Black, a massive number of games with the Australian Defense — one of his signature systems and a frequent source of wins.
- As White, deadly success with the Sicilian Defense: Sozin Attack and the Sicilian Defense: Nyezhmetdinov-Rossolimo Attack, Fianchetto Variation — both show his taste for sharp, piece-filled battles.
