This time we'll look at gambits and a variant where we forget about developing bishops in favor of occupying the center.

Introduction

Hello, hello! For the second time, we analyze interesting ideas in the best positions.

If you haven't seen the previous blog, you'll find information there about the "best positions" and where these games come from.

In this second episode, we'll look at gambits and a variant where we forget about developing bishops in favor of occupying the center.

position No803 (where bishops_in_corners)

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#0

let's start with the moves 1. e4 b5 2. Qe2 g6 3. f4, we occupy the center, not paying attention to the development of bishops

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#5

To gain space he moves c5, but we block the dark-squared bishop - e5!

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#9

He tries to undermine the center - f6, but a simple Ngf3

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#11

5...Qa5 6. Nd3 attacking c5 pawn. Let's consider the options:

  • d6 is bad because it weakens the white squares around the king and after the exchanges the move Qd6+ will be annoying
  • Qb6 is also a bad choice because after b4 we are trying to open the black king, and if c4, then the simple plan Nc5, Bd4 and g3, we have a better development
  • If b4, then b3 and our plan is to take more space g4, h3 and try to penetrate with the queen to e7 to attack the pawn on c4

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#15

So Stockfish plays c4. Then 7. Nc5 b4 8. Qxc4, but why does he sacrifice a pawn? How about a simple Nc7 or 0-0-0?

If Nc7 or 0-0-0, then push the pawn to e6!

  • If he doesn't take the pawn by playing d6, then Nd7 (on Nc7 and 0-0-0)
  • if he does take it, then we put pressure on this pawn by moving Nd4 (on Nc7, if it were 0-0-0, then the pawn would be unprotected and we would immediately take it)

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#16

Let's return to the main line, after Nc7 we still play e6, but the strong move d5!

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#20

We retreat Qd4, but he continues to attack Rb5

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#23

After 11. Nb3 Qa6 12. Re1 (defend e6) He tries to develop 12...Nh6

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#25

With this move we give the d4 square to the knight

https://adjva4.dpdns.org/study/YiDfvjnz/vmKJYP6O#33

But after precise moves and measurements we get this position. We are succeeding in development and in this variation it is difficult to play with black and white can get a greater advantage

THE LAST 2 GAMES ARE RELATED TO GAMBITS

position No457 (where bishops_in_center)

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#0

A pretty classic position to start with 1. d4 d5 2. Nd3 Nd6 3. f3 c6 4. e4?! (sac the pawn)

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#9

He doesn't accept the gambit, playing f6 to open the queen, but we attack the knight e5!

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#13

After exchanges and a one-move threat, Black is forced to retreat with his knight

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#17

Then we capture more space by moving the a-pawn. Black should have traded his bishop to avoid accumulating pieces in a cramped space.

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#19

After 9...Bc7 10. f4 we have a great position

https://adjva4.dpdns.org/study/YiDfvjnz/qVvxIGaK#33

After a couple of moves, Black still hasn't solved the problem with the queenside. We exchange queens and push our pawns further and further.

position No793 (where bishops_in_center)

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#3

Next we move on to a correct gambit where our pieces quickly enter the game.

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#12

Black chose a poor plan involving seizing space on the queenside, weakening his king. Better would have been Ne6, d5, and Qc7, attempting to complete the development.

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#16

He created a battery to eat on h2, but we ignore it for the sake of initiative - Ngf5!?

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#18

In between, he attacks the bishop with a4 and the bishop has no retreat squares, right? No, Bd5!!

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#19

If you take the bishop, then Nxd5, threatening to fork any move except.

  • If Kd8, then we bring up the last pieces after Nxc7 and play Qe4, Rc1
  • If Bd6, covering the e7-square, then Nxd6+ Qxd6 and Bb4, Qe4, Rc1

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#21

Therefore, stockfish ignores the bishop and plays Bxh2+

https://adjva4.dpdns.org/study/YiDfvjnz/3RAErQo2#23

But then he leaves his bishop trapped. After the exchanges, this is a won endgame.
