kylemeister, I see in #28 you already pointed out 8.Bg5 (Petrosian system). Regarding 8.O-O Barden wrote "The alternative 8.O-O does not promise White an advantage." See Barden / Hartston / Keene (1973) The King's Indian Defence, page 213. (Barden was responsible for the Classical variation chapters.) It's possible that theory has moved on since then, but in such a backwater it's more likely that it has been forgotten. Barden gives 2.5 pages on 8.Bg5, while after 8.O-O he gives just 1/2 page, quoting five game fragments. Note how old these games were already in 1973! I certainly never saw anything like these lines in the chess magazines of the 1970s.

we have a position which can also occur with White to move:  1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 0-0 6. Be2 e5 7. 0-0 Nbd7 8. Be3 c6 9. d5 c5 ...

Barden considers 8.Be3 under the Gligoric system (7.Be3 Nbd7 8.O-O). Interestingly on page 228 after 8...c6 9.d5 (9.Qc2 is his main line) he gives 9...c5?!, quoting one game fragment. The ?! may not be because black gets an objectively bad position, but because ...c6-c5 is not really necessary.
Similar to 8.Be3 is the older 8.Re1 c6 9.d5 c5 as played in the Bronstein - Petrosian game above. On page 203 Barden says 9.d5 "is too early". Instead of 9.d5 Barden prefers moves like 9.Bf1 (his main line) and 9.Rb1 ("fashionable"). After 9.d5 he quotes one game fragment:

Barden also notes two other move-orders, in both cases offering 8.Bg5.
page 213: 1.d4 Nf6 2.c4 c5 3.d5 e5 4.Nc3 d6 5.e4 g6 6.Be2 Bg7 7.Nf3 O-O
page 241: 1.d4 Nf6 2.c4 c5 3.d5 g6 4.Nc3 g6 5.e4 Bg7 6.Be2 O-O 7.Nf3 e5

Regarding the e3 Poison possibility 1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. e3 c5 5. d5 0-0 6. Nc3 d6 7. Be2 e5 8. e4 Ne8 9. 0-0 f5 and the old line in which White has a tempo more (these came up in replies 25 and 28), I note that Carlsen was on the black side of the latter in the first round of the Grenke Chess Classic.
https://en.chessbase.com/post/grenke-classic-2019-round-1

The annotations there contend that White is slightly better after 1.d4 Nf6 2.c4 c5 3.d5 g6 4.Nc3 d6 5.e4 Bg7 6.Nf3 O-O 7.Be2 e5 8.O-O Ne8 9.Ne1 f5 10.ef gf 11.f4 Nd7 12.Nd3 e4 13.Nf2.  After the further 13...Bxc3 14.bc Ndf6 15.Be3, we have a position which can also occur with White to move:  1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 0-0 6. Be2 e5 7. 0-0 Nbd7 8. Be3 c6 9. d5 c5 10. Ne1 Ne8 11. Nd3 (I see that this is addressed in the latest KID update) f5 12. ef gf 13. f4 e4 14. Nf2 Bxc3 15. bc Ndf6.  That version was considered unclear by Tal and by Pancyk/Ilczuk (2009); Nunn/Burgess (1996) had it as "gives Black good play."

Thanks, kylemeister. Looks like 5 a3 may be (slightly) the 'richer' option ...

I'm in no position to argue White gets an edge here (of course one wonders where he can these days!), but no less a commentator than Max Illingworth has suggested that Black's task after 5 a3 isn't that simple ... (Perhaps it's the same after 5 cd?)


I noticed that ECO had 5. cd as leading to +=, while NCO had it as =.  The difference concerned the line  5...ed 6. Bb5+ Bd7.  I see that Smith comments that that "gives an IQP-position without the light-squared bishops.  White is closer to the heavy piece-ending he is striving for, but Black is not unhappy to get rid of his bad bishop.  So both players are satisfied and White will have some slight pressure before a draw is agreed."

I also see that after 5. a3, Smith gives 5...dc (6. Bxc4 a6) an exclam.

Very interesting, Stigma, thanks!

Another approach for us sometime Reti players is to play e2-e3 only after 1 Nf3 d5 2 c4 e6/c6. That's if 2 ...d4 3 b4 is holding up of course, about which I have no idea. A subject for the Demuth Reti book thread ...

I like this reasoning (relating to the 1 d4 Nf6 2 Nf3 g6 3 c4 Bg7 move order), but for those of us interested in non-mainline options with some sting, I don't see one after 4 Nc3 d5 here to parallel the Smyslov System against 4 ...d6 (5 Bg5 then e2-e3). Is there one?

For consistency with the strategic Smyslov system, 5.h4!? is probably too sharp, and maybe not that good either. But you could look into the delayed Nadanian with 5.cxd5 Nxd5 6.Na4!? and the Exchange with 8.h3!?, the latter scores surprisingly well and has seen a revival in the last couple of years.

After writing the above I hit the database and found the "Axel Smith school of chess" answer right there: Both Smith himself and associates like Grandelius, Frisk and Lobersli have played 5.cxd5 Nxd5 6.Bg5, which can be annoying for Black to face. After 6...Nxc3 7.bxc3 c5 8.e3 White's centre is rock-solid.

Hmm.  Back in the 2000s, ECO "thought" various ways of playing by Black after 5. a3 should lead to equality (or unclarity), though I notice it didn't mention 5...dc 6. Bxc4 a6 (when 7. 0-0 is a recognized QGA line).

I'm in no position to argue White gets an edge here (of course one wonders where he can these days!), but no less a commentator than Max Illingworth has suggested that Black's task after 5 a3 isn't that simple ... (Perhaps it's the same after 5 cd?)

Quote:
Sorry, having actually checked it, the suggest move order is in fact 3 d4(!) [avoiding the Reversed Blumenfeld; 3 c4 d4 4 b4, which Axel Smith says is interesting, but less consistent with the rest of the repertoire], and then 3...e6 "transposes to the Tarrasch", in which he does indeed give the line with 5 a3(!).

Given that if you play an early e2-e3 (and want non-insipid setups) you have to be prepared to play various position types, you could argue that it's Smith's very avoidance of the Reversed Blumenfeld that's inconsistent here, especially as this is a pretty good version for White!

Quote:
You could always play something "real" against the King's Indian and Grunfeld, while incorporating Axel's lines against other openings.  4.Nc3 and White still has a ton of options. [ErictheRed on p. 4.]

I like this reasoning (relating to the 1 d4 Nf6 2 Nf3 g6 3 c4 Bg7 move order), but for those of us interested in non-mainline options with some sting, I don't see one after 4 Nc3 d5 here to parallel the Smyslov System against 4 ...d6 (5 Bg5 then e2-e3). Is there one? For this and other reasons I'm interested in the 1 Nf3 d5 2 e3 move order, when after 2 ...Nf6 3 c4 g6, White perhaps(?) has reasonable chances of an edge (or at least an incisive setup) with 4 b4, say, or with 4 cd Nd5 5 d4 (5 Qb3!?) Bg7 6 e4!?. I stand to be corrected!

I guess you mean 4 d4, when after 4 ...Nf6 neither 5 cd nor 5 a3!? are wholly innocuous ...  I've been thinking that's the best way for White to go.

3...e6 just reaches the standard QGD thingy, doesn't it?

Can someone tell us what's his poison against 1 Nf3 d5 2 e3 c5, and if it convinces? I quite like 3 c4 here after 3 ...Nf6 4 cd Nd5 5 Nc3, or 3 ...d4 4 b4, but what on 3 ...e6? Of course, there's also 3 d4 (and 3 b3 and 3 Bb5), but which lines are incisive, and which insipid?

His suggestion against the KID is a "reversed KIA": 1.Nf3 Nf6 2.e3 g6 3.d4 Bg7 4.c4 0-0 5.Be2 d6 6.Nc3 Nbd7 7.0-0 e5 8.Qc2.


Or to put it another way, it's a French Defence set up against the KIA a tempo up.

  

Those who want to go by my perverse footsteps play such pawn structure with fuzzy atypical still strategic orientations
