Koyun's style is known for being highly aggressive. He skillfully applies chip pressure, frequently raising and re-raising preflop to force opponents into tough decisions.

From Koyun's play, one can learn that maintaining high aggression in tournaments can generate significant fold equity, but it requires precise assessment of opponents' ranges and stack sizes. His preflop shoving logic with short stacks and his late-position maneuvers with deep stacks are worth studying. Players can review his hand histories to understand how to maintain balance under pressure—daring to widen ranges while avoiding the risks of over-aggression.
