Master the A-File: Chess's Most Underrated Weapon

Dear Chess Friends!

The a-file isn’t just a board edge – it’s a highway to victory. In my workshop "Playing through the A-File," we dissected how legends like Capablanca and Lasker turned this "quiet" file into a tactical superweapon. Watch the full recording here:

Why the A-File Wins Games

Core Principles:

  • Alekhine’s Gun: Rooks lead, queen supports from behind ("queen behind rooks").
  • Weakness Hunting: Target backward pawns (a6/a7) or weak squares (a2/a1).
  • Diversion Tactics: Seize the a-file to distract defenders from the king.
  • Fianchetto Power: A bishop on b2/g2 controls a1/a8 – your invasion launchpad.


4 Game Fragments That Reveal Everything

1. Lasker vs. Showalter (1896)

  • Key Lesson: Diversion & Distraction
  • 33...a4! – Black seized the a-file but overcommitted, letting Lasker counterattack on the kingside.
  • Takeaway: Never ignore your king while invading!

2. Capablanca vs. Treybal (1929)

  • Key Lesson: Alekhine's Gun
  • 42.Ra7! → 45.R1a4! → 46.Qa3! – Capa’s "queen-behind-rooks" squeeze paralyzed Black.
  • Takeaway: Stack major pieces like tanks in a convoy.

3. Capablanca vs. Alekhine (1927)

  • Key Lesson: Defensive Resourcefulness
  • 30.b6? – Capa’s premature a-file push let Alekhine hold with ...Rd7! and ...Kh7!
  • Takeaway: Control before invasion – or face counterplay.

4. Evtifeev vs. Daniuszewski (1909)

  • Key Lesson: Rook battery on the 2nd rank
  • 36...Bxb3 & 37...Nxe4 – 2 Rooks on the second rank provided Black with tactical opportunities
  • Takeaway: Invasion through the a-file provides winning tactics

The 3-Step A-File Blueprint

  • Seize It
    Trade pawns (e.g., b5xa6) to open the file.
    Example: Capablanca’s 36.b5! axb5 37.axb5
  • Control It
    Double rooks + queen in Alekhine’s formation.
    Pro tip: Use a rook on a7/a2 as a "stepping stone" for deeper invasion.
  • Exploit It
    Attack weak pawns (a7/a2)
    Create mating nets (Qa1+Rxa2#)
    Force king exposure (sacrifices on a8/a1)

Hi!
My name is Victor Neustroev. I'm a FIDE Master with Elo rating 2305.


Experienced chess coach specializing in tactics and openings. An author of educational chess courses on different learning platforms.

Affordable rates! A test lesson is also possible!

I'm 34. I live in Russia, Novosibirsk. I learned to play chess when I was 5. I regularly won prizes at Novosibirsk region Championship and Siberia Chess Championship among juniors. I'm a champion of Novosibirsk City Chess Club at 2002 and a champion of Novosibirsk at 2019.


I got Master's Degree in Economics at Novosibirsk State University and also played for its chess team.


Today I am focusing on teaching chess online and offline. The reason why I do this is because I feel happy when see how my students achieve success.

 

I teach juniors since 2002. Almost all of my students were ranked. Some of them got prizes at Novosibirsk region Championship.
I also work with adults.

 

I will teach you how to find tactical strikes in certain position types and how to classify them. I can help you to improve you calculational ability. I also teach you chess openings and I believe you know how important they are. According to the statistics right-playing of the opening makes from 30 to 60% of your success (the exact number depends on your level).
Please, check my youtube videos to know how I teach and what you will achieve working with me.
