Antoni is not afraid to color outside the lines. His repertoire mixes practical tries with gloriously unorthodox choices. He has played the Amar Gambit hundreds of times, and he happily steers into the Nimzo-Larsen Attack with consistent results. In blitz he is equally comfortable in sharp Sicilian lines like the Najdorf and in slow-burn French structures.
His opening habits make him a nightmare to prepare against. One moment he is delivering a Siberian Attack, the next he is dancing around a Barnes Defense. That unpredictability is a big reason his win rate stays healthy across thousands of online games.
