**I briefly touched on the Hennig-Schara Gambit in my last post (an opening named after two players).**

**But after I reviewed it, I thought it might be a fascinating subject to share. So here are some surprising opening moves for you, the good reader.**

**The gambit starts with the moves, 1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4. White gets an early advantage while Black develops. The game can easily enter lines where tactics and unclear continuations come into play.**

**Basically, with the c-file and d-file open, Black’s dream position would be one that he would castle queenside and have the enemy king stuck in the center. This obviously cannot happen in all games as can White castle kingside and Black often has a problem developing his b8-bishop, necessary for him to castle queenside.**

**But before going over the main lines, let’s first take a look at well-known trap that many Black players fall into, especially in speed chess.**

**Fidlow-I. MayerBerlin, 19501.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4 5.dxe6 dxc3?**

**6.exf7+ Ke7 7.fxg8=N+! Rxg8 8.Bg5+ 1-0**

**Instead of 5…dxc3? Black should have responded with 5…Bxe6 and gain a tiny, minute advantage.**

**Zeljko Mackovsek-FM Sergey TrussevichJosipa Ipavca MemorialSentjur, Slovenia, Sept. 14 20111.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4 5.dxe6 Bxe6 6.Ne4 Nf6 7.Nxf6+ Qxf6 8.Nf3 Nc6 9.g3 Bc5 10.Bg2 O-O 11.O-O Rfe8 12.Bg5 Qg6 13.a3 h6 14.Bf4 Rad8 15.Ne1 Bg4 16.Bf3 Bh3 17.Bg2 Bg4 18.Bf3 Bxf3 19.Nxf3 d3 20.exd3 Rxd3 21.Nd2 Nd4 22.Qb1 Ne2+ 23.Kh1 Nxf4 24.Qc1 Qc6+ 25.f3 Re2 0-1**

**Which leaves White with taking the pawn. He can either take it immediately with 5.Qxd4 or the move after with 5.Qa4+ Bd7 (played to disrupt Black’s development and close the d-file, at least for the moment).**

**White’s first plan, 5.Qxd4 is an obvious move. Black’s response is overwhelmingly in favor of 5…Nc6, if only because 5…Nf6 fails.**

**Marshall-HowardSylvan Beach, 19041.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4 5.Qxd4 Nf6?! 6.e4 exd5 7.exd5 Be6 8.Bb5+ Bd7 9.d6 Nc6 10.Qd3 Be6 11.Bf4 a6 12.Bxc6+ bxc6 13.Nf3 Qb6 14.O-O Rd8 15.Rfe1 Nh5 16.Rad1 Qb7 17.Be5 Nf6 18.Bxf6 Rxd6 19.Nd4 gxf6 20.Ne4 c5 21.Nxd6+ Bxd6 22.Nxe6 1-0**

**And White almost has to play, after 5.Qxd4 Nc6, the move 6.Qd1, as 6.Qa4 fails spectacularly.**

**Rejfir-MenchikMaribor, 19341.c4 e6 2.Nc3 d5 3.d4 c5 4.cxd5 cxd4 5.Qxd4 Nc6 6.Qa4 exd5 7.Nf3 Bc5 8.Qb5 Qd6 9.g3 Nf6 10.Bg5 Ne4 11.Nxe4 dxe4 12.Nd2 O-O 13.Nxe4 Bb4+ 14.Bd2 Bxd2+ 15.Nxd2 Nd4 16.Qc4 Be6 17.Ne4 Qb6 18.Qd3 Rac8 19.Nc3 Qxb2 20.Rb1 Qxc3+ 0-1**

**10…Bb4+!! 11.Kd1 Nxd4 12.Qxb4 Nc2 13.Qe4+ Be6+ 0-1**

**And now with the moves 1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4 5.Qxd4 Nc6 6.Qd1, a tabiya has been reached, with chances for both sides.**
