Subject: The Cochrane Gambit
Hi folks,

I was wondering one day what would happen if Black took on e4 right away in
the Cochrane gambit. I found that White has a number of winning lines. Some
lines were surprising. Black has to really watch himself. Here is some
analysis.


1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nxf7 This is the Cochrane Gambit 4...Kxf7 5.d4
Nxe4? I wanted to see if I could exploit this early capture. If I can come
out a pawn up at the very least I will be happy. Gaining a pawn while
Black's King is stuck in the center is a nice advantage. 6.Qh5+ Ke6 [6...g6
7.Qd5+ Kg7 8.Qxe4 White wins the Knight] 7.Bc4+ d5 8.Qe5+ Closing in on the
King 8...Kd7 9.Qxd5+ This move is only good enough for a draw against proper
play. But a lower ranked player will have a lot of trouble with it. There
are some potential mistakes that Black can make. [9.Bxd5 Threatening mate
9...Qf6 10.Bxe4 Qxe5 11.dxe5 White is up material] 9...Nd6 Only way to get
the draw. [9...Bd6 Looks logical but loses in two. 10.Qf5+ Ke7 (10...Kc6
11.Qb5#) 11.Qf7#] 10.Qe6+ Kc6 11.d5+ Risking all for the win. This move
loses if Black defends properly. [11.Qd5+ Secures the draw] 11...Kc5 Steps
into the forced mate. This move looks very tempting because Black is
attacking the Bishop and the Queen at the same time. [11...Kb6 Is okay]
12.Qe3+!! SUSRPRISE!! White sacs the Bishop too. 12...Kxc4 Black might as
well eat as much material as he can. [12...Kb4 Obviously a poor try 13.Qc3+
Kc5 (13...Ka4 14.b3#) 14.Be3#] 13.Qd3+ Another key move. White's Queen takes
the place of the white squared Bishop. 13...Kc5 14.Be3+ Kb4 forced 15.a3+
[15.Qa3+ Here is another way to mate Black 15...Kc4 (15...Kb5 16.Nc3+ Kc4
17.Qb3# (17.Qc5#) ) 16.Qb3# (16.Qc5#) ] 15...Ka4 16.Nc3+ Ka5 17.b4# A
pleasing win for White 1-0

5...Nxe4? is an error, White is immediately better and probably
winning. Correct is 5...c5!.

Yes, but the point is to show why. Which is exactly what I did. Thanks.

OK, but why bother delving into lines that are easily evaluated when
there are many more interesting and unclear lines in the same gambit?

Why? Because someone may take the pawn in an actual game and it would be
helpful if you had an idea of what to do prior to that happening. Especially
in speed chess games.

I doubt anyone who is faced with the Cochrane gambit will take the
pawn more than once.

7. Qg4+ is enough to get a far superior position with an extra pawn.
The lines that follow are very speculative.

Well, that's what a computer would say but the defense looks pretty
horrid and I doubt Black is that well off.
