Chess Opening Theory/1. e4/1...e5/2. Nf3/2...Bb4

not chess opening theory. vanity name, strange analysis.== 2...Bb4?! — Radium Gambit == After 1. e4 e5 2. Nf3, Black plays 2...Bb4?!, developing the bishop to b4 and creating an unusual position. Its a rare move in chess and considered dubious. It was not played ever in the Masters Database + Grandmaster Play. 3. Nxe5 can take the e5-pawn, immediately challenging Black's center (Radium Gambit Accepted). 3. Bc4 develops the bishop and prepares to castle. 3. Nc3?! develops another piece and challenges Black's bishop, although Black can force a trade with 3... Bxc3 4. dxc3 (or bxc3). 3. c3 attacks the bishop and prepares to build a strong center. 3. a3 attacks the bishop with a flank pawn. 3. Bb5?! will turn into the Radium Gambit - Mohan Variation. Bad Moves: 3. Qe2? develops the queen, but it blocks the bishop on f1 and does not address Black's pressure on the e4-pawn. 3. g3? prepares to fianchetto the bishop, but delays development and allows Black to maintain pressure on the center. 3. c4? probably a mouse slip intended to play 3. c3 , it also delays development. Downsides: The main drawback of 2...Bb4?! is that Black develops the bishop before properly defending the e5-pawn. White can potentially exploit this with Nxe5. The Radium Gambit is an extremely unusual line and could plausibly originate from a mouse slip intended to play the Busch-Gass Gambit, where Black accidentally plays ...Bb4 instead. An independent line is 1. e4 e5 2. Nf3 Bb4?! 3. Nxe5 Qe7!, when White wins the e5-pawn and Black must look for compensation through rapid development.
