**There is an opening, or rather a gambit, that appears to have no name. Yet, this series of moves is well-known among most chess players. But no matter what you may call it, Black doesn’t do that well.**

**Let’s look at it.**

**1.e4 b6**

**Now known as a Owen’s Defence, this move seeks to avoid main lines after 1.d4 and 1.e4. But as you will soon see, there are main lines that arise from 1.e4 b6 as well. And one of those lines is the gambit.**

**2.d4 Bb7**

**White takes advantage of the opportunity to take the center.**

**3.Bd3!?**

**Usual move here is 3.Nc3 e6 with similarities to a Nimzo-Queen’s Indian hybrid.**

**Before we get to the gambit line, let’s look at some tamer, and safer, Black lines.**

**4.exf5**

**This move lets Black spear the h1-rook. But this move is probably the best for White. Things now get very interesting.**

**Black cannot immediately take the g-pawn as he loses quickly.**

**Here is the game that popularized White’s response to Black’s gambit.**

**Greco-N.N.**

Rome 1620?

**1.e4 b6 2.d4 Bb7 3.Bd3 f5 4.exf5 **(White is willing to give up his rook to get the king.)** 4…Bxg2 5.Qh5+ g6 6.fxg6 Nf6 **(This is a huge error. Black has to play 6…Bg7 7.gxh7+ Kf8 8.hxg8=Q+ Kxg8 and while White’s rook may fall, Black has to worry about his very exposed king. Amusing by the way, is 6.fxg6 e5? 7.g7+ Ke7 8.Qxe5+ Kf7 9.gxh8=N#)** 7.gxh7+ **(White is now willing to give up his queen for the forced mate. King safety is more important than safety for the rook or queen, and even both. Note: While 7.g7+ Nxh5 8.gxh8=Q Bxh1 9.Qxh7 would eventually win, the text move is faster, and fast attacks are always better for winning the game (less mistakes possible) and for one’s own ego.)** 7…Nxh5 8.Bg6mate 1-0**

**So Black must do something other than to immediately take the g2-pawn or the h1-Rook. In fact, he can never the rook (due to the tempi needed to take the rook and the fact that his king ends up being a target). And probably can’t ever take the g2-pawn either.**

**Here is why he can never take the rook:**

**Well, If Black can’t take the h1-rook, or the f3-knight, can he at least take the g2-pawn? Black must play this move to gain any material for the attack that is about to commence on his side of the board, so he is virtually forced to play into this variation with the queen check.**

**Maybe Black can play 4…Nf6 and wait a tempo or two before snagging the g2-pawn. Can that win the game for him? I don’t know, but with the games on hand, I wouldn’t count on it.**
