Representative Game: Practical Pressure from d4 Territory

This game did not formally enter Jobava territory. Yet many familiar practical ideas remained present. Active development, early initiative, piece pressure, and direct kingside targeting quickly replaced slower positional play. The attraction of d4 systems was rarely limited to memorized move order. More important was the recurring practical mindset: create activity, recognize attacking patterns, and increase pressure before the opponent fully stabilizes.
