About this opening
The Jaenisch Variation (2.Bc4 f5 3.d3) is the measured reply to the Calabrese Countergambit: rather than capturing on f5, White first props up e4 with d3 and prepares quiet development. The idea is to highlight the weakening created by ...f5 without exposing itself to immediate complications. The play stays tense, White aiming for a stable strategic edge on the light squares.
