Little review of Accepted From's gambit

Yigor

We start with the following position (ev=+0.4):

 

 

Here black has several options:

  • Main line 2...d6 (ev=+0.4)
  • Schlechter gambit 2...Nc6 (ev=+0.4)
  • Lasker gambit 2...f6 (ev=+0.6)
  • Greco variation 2...Qh4+ 3. g3 (ev=+1.1)

Well, the Greco variation is natural but unsound. Historical games:

Greco - NN (1620, 1-0) http://www.chessgames.com/perl/chessgame?gid=1272149

NN - Du Mont (1802, 0-1) http://www.chessgames.com/perl/chessgame?gid=1250613

Simons - Smith (1852, 1-0) http://www.chessgames.com/perl/chessgame?gid=1336286

 

Other interesting variations:

  • Langheld gambit 2...d6 3. exd6 Nf6 (ev=+0.7) --> post #7
  • Lasker variation 2...d6 3. exd6 Bxd6 4. Nf3 g5 (ev=+0.7) --> post #13

 

(to be continued, posts #4, #7, #13)

I will mainly consider the Main line and Schlechter gambit. The next step:

  • Main line 2...d6 3. exd6 (ev=+0.3)
  • Main line: King's Knight 2...d6 3. Nf3 (ev=+0.4)
  • Schlechter gambit: Classical variation 2...Nc6 3. Nf3 (ev=+0.7)
  • Schlecter gambit: Modern variation 2...Nc6 3. Nc3 (ev=+0.4)

How does the evaluation look when you decline the gambit with 2.e4?

U obtain the King's Gambit with evaluation about -0.5. explorer.pngwink.png

The main line continues like that (ev=+0.4):

 

 

There is also an interesting sideline called Langheld gambit (+0.7):

Whattt? Are you saying this crap is better regarded by stockfish (+0.4) than the KI?

The main line can have very funny checkmates if white doesn't realize what's up.

But I'd like to learn what happens if white plays a little bit smart.

In your last diagram, there are clearly 2 straightforward attacks: 4...Bg4 (ev=+0.5) and 4...g5 (ev=+0.7, Lasker variation). Evaluations are approximative, they depend on depth. These variations were played classically and I'm planning to review them. peshka.png Please contribute if  U are interested. wink.png

I think that f6 is a good choice for bullet and blitz because you can use the f-file.

Let's concentrate ourselves on the main line:

 

 

Black has several relatively good moves here. The most known is the Lasker variation 5...g5 (ev=+0.7). An other possibility 4...Nh6 (ev=+0.5) occured the first time in the following Mollerstrom - From game (1862, 0-1):
