Regarding 4...a6 5 f4, I think 5...b5 is critical. The first thing I'd looked at was 6 e5, but I wasn't totally convinced after 6...b4 7 Qf3 c6 8 exf6 bxc3 9 fxe7 Qxe7 10 bxc3 - it looks like Black has decent compensation after ...Bg7, ...0-0, ...Re8 and ...f5.

I think 6 a3!? (N) might be interesting, just with the idea of playing e4-e5 without ...b4 being available as a reply. 6...Bg7 7 e5 Ng4 8 Bd2 0-0 9 Qf3 looks better for White, but a better try is probably 6...Bb7 7 e5 Nd5 8 Nxd5 Bxd5, when it feels like White should be able to organize a favourable b3/c4 push, but I haven't found a completely convincing way of doing this without running into a well-timed ...c5.

Marin gives 5.h3 Nbd7 6.f4 (6.g4 b5) 6...e5.  Of course his book is out on Forward Chess.

Hi.

I remember thinking that ...a6 or ...c6 could be considered "concessions" in a sense, allowing White to favourably switch to an Austrian Attack, in the latter case perhaps with 5 f4!?, and in the latter with 5 h3, followed by f4, Nf3, Bd3 and meeting ...b5 with a2-a3. I thought this was pretty pleasant for White (although evidently Marin disagrees!).

4.Be3 a6 5.f4 is a line I would like to look into further. I'm not 100% sure that black is OK, which bothers me a lot.

Hopefully Marin will have something decent against 4...c6 5.h3 Cool

At some point I decided the 5...0-0 line was the only one I'd be willing to play with Black. This was because allowing ...e5 seemed totally harmless, while I couldn't find an advantage after 6 Nf3 a6 7 Bh6 b5 8 Bd3 Nc6!. This left 6 0-0-0, which isn't ideal as it castles into an attack, and seemed a bit too complicated for a practical weapon. The only slow game I had this variation in was a 45|45 training game on the internet (which incidentally began 4 Bg5 Bg7 5 Qd2 0-0 6 0-0-0, and transposed after an eventual Bh6). In that game, Black made (in my opinion) the mistake of (after 6 0-0-0 c6 7 f3 b5 8 Bh6 Qa5 9 Kb1) playing ...b4 before ...Be6. Chasing the Knight back to e2 and then playing ...Be6 allows Ne2-c1, when the Queenside is very solid (Knight on f8; no mate mirrored), and I eventually won with a Kingside attack. I believe I concluded afterwards that playing ...Be6 before ...b4 in some form avoids the maneuver to c1 and gives Black better attacking chances. I'm not sure I ever got around to analyzing this more deeply.

Not typically. 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 Bg7 5.Qd2 O-O 6.O-O-O c6 7.f3 b5 8.h4 and 8.Bh6 belong to the most tactical lines of the entire opening, as razor sharp as the the sharpest Dragon or Najdorf.

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 Bg7 5.Qd2 0-0 
Is very much distinct from lines where black waits with castling, that is true.

It has been some time since I checked, but I remember thinking black's play was a bit insufficient if white played accurately. Anyway. Maybe looking at this line would be good to start off with, since if it works to just play 4...Bg7 and 5...0-0 (pretty much the most natural moves) then why bother playing something else.

Shaw's analysis of 6.Bh6 was not conclusive as far as I could tell (black should be able to improve). So, much like Vigus and MNb concluded in 2009, 6.0-0-0 still seems like the biggest problem imo.

Besides specifying Black's 4th move you should begin with specifying White's 5th and 6th. 4.Be3 c6 5.Be2 Bg7 6.Nf3 O-O turns into a classical ....

Argentinean Attack: White plays Be3, Qd2 and f3.
150 Attack: White plays Be3, Qd2 and Nf3 (eventually h3 first).
Pseudo-Argentinean Attack: 4.Be3 Bg7 5.Qd2 c6 6.Bh6.
Pseudo-Austrian Attack: 4.Be3, 5.h3 and 6.f4.
Archbishop Attack: 4.Be3, 5.h3 and 6.g4.

I was thinking about trying to get to grips with:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 a6 5.Qd2 b5 6.f3
Not that the above systems are not interesting to look at as well. Thanks for listing them clearly by the way. As it stands now I'm fairly sure I will first try to see if I can't find anything playable for black after 4.Be3 Bg7 5.Qd2 0-0 though.

I'd definitely be willing to discuss this as well. Want to see if Marin reaches this (or the same position with 6.Bh6 though via a 4.Bg5 move order) first though.

Have a nice day.

"And that in all three of these lines (even if it is not immediately clear after 4...Bg7) the main strategic idea for black is to advance b7-b5."
In many lines to advance e7-e5 is at least as important.

"Heavy strategic play typically ensues."
Not typically. 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 Bg7 5.Qd2 O-O 6.O-O-O c6 7.f3 b5 8.h4 and 8.Bh6 belong to the most tactical lines of the entire opening, as razor sharp as the the sharpest Dragon or Najdorf.

Lines with the early sally ...Ng4 with very few exceptions are good for White.

I play the 4 Be3 line with White but haven't looked at it all that much, mostly because I'm not facing the Pirc all that much. I wrote this in my notes as a general justification for why I believed 4 Be3 is a good move:

Basically, the move ♗c1-e3 is a very generic one. It fits it with the most number of set-ups. Depending on what Black does, White retains the option of going for an Austrian Attack with f2-f4, the traditional 150 plan of ♕d2 and 0-0-0, as well as a Classical plan involving ♘f3, ♗e2, h3 and 0-0.

I remember thinking that ...a6 or ...c6 could be considered "concessions" in a sense, allowing White to favourably switch to an Austrian Attack, in the latter case perhaps with 5 f4!?, and in the latter with 5 h3, followed by f4, Nf3, Bd3 and meeting ...b5 with a2-a3. I thought this was pretty pleasant for White (although evidently Marin disagrees!).

4...Bg7 was the line I was most unsure about. After 5 Qd2, Black obviously has 5...c6 and 5...0-0 as reasonable options.

For a while I thought the ...Qxf2+/...Ng4+xh6 ending resulting from the 5...c6 line was just good for White, but eventually realized it wasn't so simple - I'll have to take a deeper look at this at some point.

At some point I decided the 5...0-0 line was the only one I'd be willing to play with Black. This was because allowing ...e5 seemed totally harmless, while I couldn't find an advantage after 6 Nf3 a6 7 Bh6 b5 8 Bd3 Nc6!. This left 6 0-0-0, which isn't ideal as it castles into an attack, and seemed a bit too complicated for a practical weapon. The only slow game I had this variation in was a 45|45 training game on the internet (which incidentally began 4 Bg5 Bg7 5 Qd2 0-0 6 0-0-0, and transposed after an eventual Bh6). In that game, Black made (in my opinion) the mistake of (after 6 0-0-0 c6 7 f3 b5 8 Bh6 Qa5 9 Kb1) playing ...b4 before ...Be6. Chasing the Knight back to e2 and then playing ...Be6 allows Ne2-c1, when the Queenside is very solid (Knight on f8; no mate mirrored), and I eventually won with a Kingside attack. I believe I concluded afterwards that playing ...Be6 before ...b4 in some form avoids the maneuver to c1 and gives Black better attacking chances. I'm not sure I ever got around to analyzing this more deeply.

I suppose I've been playing Plan D against 4...a6 and 4...c6, and Plan C against 4...Bg7.

These are my very general thoughts, not really based on that much concrete analysis - hopefully this thread will make me do some!  Cheesy

Pirc 4 Be3: Best Lines/Move Orders

Hello Chesspub.

After seeing the ”4 Bg5: Best Lines/Move Orders ” Pirc forum thread generate both discussion and analysis I think trying to create a similar thread for 4.Be3 Pirc would be fun and potentially interesting. Just like in that thread subject of discussion is whichever line/-s of the 4.Be3 complex seems interesting to discuss, previous analysis – for example in chess books, general strategic considerations, best move orders, games, history, etc. etc. In short pretty much everything.

As for discussion of lines that are not strictly reaching the position after 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 (the 4.Be3 Pirc), for example 1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.Be3 (the 4.Be3 Modern) or more distant connections. I personally don't mind if they end up being discussed in the thread as well. Ultimately mods decide matters of structure though.

My own understanding of the Pirc version: 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 is that black essentially has three moves
a) 4...Bg7
b) 4...c6
c) 4...a6
And that in all three of these lines (even if it is not immediately clear after 4...Bg7) the main strategic idea for black is to advance b7-b5. This gains space, prepares a strategically disruptive pawn push b4 and creates a square on b7 for black's often quite poor light squared bishop.

White pretty much has four ways to face this:

Plan A) Try to delay or possibly even prevent b5 by making it not good for black to play
This is usually done by making sure b5 is met by e5 directly. All of f4, Nf3 and h3 can act as prepatory moves for e5. Sometimes black finds some way to play b5 later even if white stops it for x number of moves. By then though, it could be less effective.

Plan B) Play a4 to stop b5 
Maximalist of course. Arguably though the Pirc is a minimalist opening for black so there is perhaps some sense in white going the opposite way.

Plan C) Let black play b5 and then meet it with f3 
Not playing to pressure black immediately and instead solidifying a central pawn formation, which arguably is a clear strategic asset. Heavy strategic play typically ensues.

Plan D) Allow b5 but make sure f3 is not played in response
Many setups exist for white. Widely different.


There are many lines after 4.Be3 obviously so I don't know where to start. Noticeably however there seems to be some recent interest in the Argentinian (Be3, Qd2, f3) against a6 setups here on this forum. Maybe that is good to discuss first. I thought I'd check some books to see if their lines make sense for example.

Personally I am also interested to see if  it is possible to construct a repertoire for white against 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 that avoids the strategic fights which can ensue if black gets to both develop and play b5. I have some ideas on how to put a bit of early pressure on black.

Have a nice day.
