1. e3 e5 2. e4 - King's Isa Reverse Opening edit
An irregular opening, considered somewhat passive. Play may transpose to lines of the Chess/Reverse Petrov Defense (Nf6–Nf3), Chess/Reverse Englund Gambit (e4–d5), or reversed Rousseau Gambit (Nf6,Nc3-Bc5,f4).
The King's Isa Reverse Opening is not popular. According to ChessBase, it ranks eleventh in popularity out of the twenty possible first moves.
After Van't Kruijs Opening 1.e3 e5, White play 2.e4!? , therefore making it a truly reversed Double King's Pawn Opening (or Open Game). This is often used when White has much knowledge of the opening when playing as Black. Therefore, this can be used to ensnare a few opponents into traps. However, since this gives the first move advantage to Black straight away, this is not recommended. Similarly, 1.e3 f5 2.e4 goes to a reversed From's Gambit, where White is practically playing as Black.
