If you want to have a “simple to learn” chess opening that can give you a win as early as move 8, and also surprise your opponent by playing it, you’re going to love this.

In this video lesson, GM Igor Smirnov will show you one of the most underrated chess openings that will help you beat even stronger opponents.

The opening is called the Colle System, also known as the Colle–Koltanowski System, which is a variation of the Queen’s Pawn Game and is characterised by a systematic development of White’s minor pieces to support a quick pawn move to the e4-square.

A lot of the chess players underestimate this system and none of the top GMs play it because it looks slightly passive. However, in reality, this opening has great potential with plenty of hidden attacking opportunities that almost no chess player is aware of.

  1. So this opening is taking advantage of the Greek gift, which is the real weapon of the system.

  2. Not very often see black play early e6 blocking the white bishop in in lower levels.

  3. EXCELLENT video! clearly explains very limited number of simple ideas.

  4. Thank you. This has really opened up my game and provided a new insight on how gambits can really open up space. Many thanks

  5. How we defend against this openning when we play black

  6. show a vid defending against those attacks by white

  7. Yoooo i did this for the first time a few mins ago and DESTROYED my opponent. They did somethings different but i kept the exact same setup you said, i ended up getting their Queen and they resigned lol. Thanks!

  8. When I was a C level player, I played this all the time. The problem comes when black plays Be5. Almost all of your threats are now gone.

  9. Black should move bishop to h2, sacrificing the bishop to capture the pawn..
    Reason 1: white can either recapture with the rook or slide the king back
    Reason 2: a skilled enough player can afford to capture white’s rook with a queen sacrifice, which is delaying white from getting black’s h7 pawn because white will have to take blacks queen to prevent threats from the piece, such as winning the rook on a1
    Reason 3: once the rook is captured, black can move the g6 knight to f4 and attack white’s queen before the checkmate can be set in motion

  10. Keep this AWAY from Naroditsky !
    He will bodybag the whole thing …. 👻

  11. This is a good example why I hate "youtube chess teachers". In the real world, under 2000 ELO, 99% of people plays c4 with black. But here there is not a single mention to it.

  12. I wish you guys would learn to pronounce pawn with a Texas accent….

  13. I just won 3 games in a row using this. Much more aggressive and quicker than the London system.

  14. It missed pawn c6 for black early in the opening. i don't see why that doesn't completely ruin everything for white

  15. Odd that you didnt call the Bxh7+ its most common name – The Greek Gift Sacrifice. I used to worry about it and had to be aware of potential threats against g7 as well. Since I started playing exclusively KID, KIA, Pirc, Gruenfeld systems, I don't have those kind of worries. I play every day almost and from a KID or Pirc perspective, Colle is a hard setup to crack.

  16. When it comes to White 1 d4 systems, I prefer the London (2 Nf3, 3 Bf4). [Bc1] is better outside the pawn-wall than inside it. Then when it comes to games with White after 1 d4, I prefer 2 c4 anyway. Better control of the centre. And when it comes to games with White, I prefer 1 e4. Best by test.

  17. If black move bishop to F6, white's queen is lost. It might not change the outcome of the game, but it will at least make things more interesting.

  18. He could simply move pawn C5-C4 attacking the bishop

  19. What is the best way to avoid this trap with this opening?
    1.d4 d5

    2.Nf3 Nc6

    3.e3 Bg4

    4.e3 Bxf3

    5.Qxf3 Qd6

    6.Bd3 O-O-O

    7.Nd2 e5

    8.dxe5 Nxe5

    9.Qd1 Nxd3+
    10.Ke2 Qa6
    11.b3 Nxd1

  20. I love this opening, and use it ll the time now with increased success. I greatly appreciate you sharing it.

    As I advance (850-950) I find opponents increasingly have some serious disruptors to prevent me creating the initial position – eg:

    a. …2(or …3, or4) B-F5 blocking my intended bishops development to D3.

    b. …2(or later) P-E5 attacking my positional pawn on on D4. If I ignore it, he forwards it to e4 blocking my pawn advance and forking my bishop and night!!

    c. And Occasionally ….P-C5

    d. The position rarely occurs when his knight and bishop are in the position, you decribe, to be forked by my P-E5

    e. Also, I occasionally try this opening when I am black, and am feeling my way to occasional success with it. Do you recommend this?

    f. I wonder, with this and maybe other aspects, if there is enough here to create a follow up video on this excellent opening. If not, any comments from you, on these aspects, would be welcome.

    Thanks again for this (and others) excellent video(s).

    Schaun.

  21. Lost first game with this, they play better moves what you show

  22. Lol I watched the video and won in a 10 minute rapid game on Lichess. Literally the first time I played this opening. Instead of e6 he played the more natural move (I think) Bg4. I still attacked the centre, but computer thought e4 should be played before Re1. Very interesting

  23. Ok…You can't just continue to develop this system "whatever black does" when black decides to completely depart from the standard development shown in the video. 😀 Apparently, my opponent has his own mind when it comes to playing against this opening, and now I'm in trouble. 😉
    1. d4 d5
    2. Nf3 Nc6
    3. e3 Nf6
    4. c3 Bg4
    5. Bd3 Bxf3

    Can you maybe address some strategies for making the system work when black decides to develop the white bishop early?

  24. A-1 video! very good explanation, better than anybody else, your'e a good orator – thanks Grand Master !!

  25. This is really a good opening but what i understood you cant play e4 e5 newer???

  26. Thank u. My rating 400 now with this opening

  27. Hi Igor..
    Many thanks for the awsome chess lessons you share..
    Is it correct or possible to play this system against king's indian set up?

  28. I'm a terrible chess player, been playing this and went from 743 to 880 this week, I still don't really pull off any of these slick moves but it seems solid, I don't really like it as black either but it's better than what I usually do apparently haha

  29. Isn't this just a london without the dark squared bishop developed?

  30. .., Rd8
    Bg5 is blunder because of Bf8 trapping white queen

  31. No… Bg5 is not good for white, black will place his dark bishop to Bf8 trapping white Queen

  32. Bg5 works….If Black plays Bf8 trapping White's Queen, simply sac the Queen for the Bishop…then no matter what Black plays, White follows up with BxNf6, followed by Ng5….with winning continuations no matter Black's play.

  33. Made a Brilliant move with this Opening thanks for the tips !

  34. I find your videos extremely useful, but I wish you would explain more black openings.

  35. Whenever I play this (around 1700 level) black uses anti Colle tactics, so it never goes down these pleasant lines for white, and often ends up in more of a queens gambit declined position.

  36. What if 1.d4 d5 2.Nf3 Bf5, what is the continuation?
