1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nxe4 6.Bc4 Bb4+!? Accepting the challenge Black goes pawn hunting. Such move is seldom employed although it has not been refuted. 7.c3 dxc3 8.0-0 0-0 9.Qb3 Monson's move

9.Qc2?! It's weak: 9...Nd2 10.Bxd2 cxd2 11.Nxb4 Nxb4 12.Qxd2 Nc6 And White's hasn't enough compensation.;

9...Nc5 An interesting idea. Black aims to gain a move in order to reach e6 with the knight, consolidating the position and creating difficulties to White in the development of the dark square bishop. These difficulties will limit White's possibilities to launch a quick attack with all the pieces. 

[Black should better avoid further pawn hunting: 9...cxb2!? 10.Bxb2 Ba5 11.Qc2 Ng5 (11...Re8? It's an apparently good move that instead leads to disaster. 12.Rae1!!

More challenging is the Bishop withdrawal 9...Bc5 10.Bd3 Re8 11.Bf4 Considering the output of this game, White needs to look for something else. (For instance: 11.Bxe4!?

10.Qc2 Ne6 [10...cxb2 11.Bxb2 and white has solved the issue of the bishop development (but also 11.Qxb2 Na4 12.Qc2 has to be taken into account) ] 11.bxc3 In order to free the e1 square for the Rook 11...Bc5 12.Re1 Re8 [A natural move. But a more critical alternative is 12...Ne7! threatening to change the knights or to deliver the knight to g6, thus enhancing Black defense possibilities. Furthermore Black can occupy the center with the d5 pawn pushing in c6 and d5. ] 13.Qe4 [or 13.Ng5 Nxg5 14.Rxe8+ Qxe8 15.Bxg5 ] 13...Be7 14.Bd3!?
