What is the strongest reply to Czyzewski Opening? I was exploring hypermodern openings and had found Czyzewski Opening.

[fen ""]

1.e4 e5 2.b3


How I should react to this type of situation on the board. Is this some kind of trap?
2.b3 is so vanishingly rare after 1.e4 e5 that you really should not bother preparing anything against it unless you have a friend who plays it all the time or something. Emms in Play the Open Games as Black, a repertoire book for Black after 1.e4 e5, does not even mention it.


  How I should react to this type of situation on the board.


Bologan's Black Weapons in the Open Games suggests starting with 2...Nf6 3.Nc3 Bb4, which seems as good as anything.

No.
