**Let’s get some background information first.**

**Most of us have played the King’s Gambit, and some of us still do. It’s a good opening to learn tactics and, occasionally, strategies. The majority of the games start with 1.e4 e5 2.f4 exf4 3.Nf3. Black can continue with 3…g5 and try to hold on his extra pawn, or play for his own attacking possibilities.**

**A rarer response is 3.Bc4, known as the Bishop Gambit. This variation allows White to explore relatively unknown territory.**

**Black usually counters with 3…Qh4+ moving the king, preventing White from castling, and isolating the h1-rook for at least the time being. But a queen check rarely ends the game. Black needs more active pieces to start any attack. He can try, after 3.Bc4 Qh4 4.Kf1, with 4…d5 and 4…Nf6, both leading to strong tactical play.**

**But perhaps the stronger reply is also the rarest. Black can play 4…b5!? The idea is since Black is up a pawn, he can give one up and still be of material equality and can even gain a tempo if White plays 5.Bxb5 (which is the most common move). And the extra tempo comes when Black plays 5…Bb7. This puts the bishop on the long diagonal to the white king, unable to castle.**

**Does this mean the Black wins? Not by a long shot! White has a lot of momentum built up, just waiting for Black to slip.**

**Here is the Immortal Game!**

[It is a toss-up whether the immediate 5…Bb7 or 5…Nf6, delaying the Bb7 until the knight is better positioned.

Here are two games with 5…Bb7.
