Opening Overview: Portuguese Opening

The Portuguese Opening (C20) is a notable Portuguese Opening variation, marked by the move Bb5. This setup tests tactical precision.

Strategic Context: Instead of the standard Ke2, the player opts for Bb5. It succeeds by sacrificing popularity for a statistically stronger weapon. This move exerts pressure on the e8-h5 diagonal. Plans should focus on how to control the long diagonal to exert lasting pressure and develop rapidly.

Next Steps: From here, play often proceeds with c6 or Nc6, leading into the Open Game.

Data Analysis: Statistical models suggest White advantage (Eval: +1.18), with a high probability of a draw.
