I think Williams is right on 1.Nf3 e6 2.g3 f5 3.Bg2 Nf6 4.0-0 Be7 5.d3 0-0 6.c4 d6 7.0-0 Nc6 8.e4 (8.Rb1 Qe8 9.b4 e5 10.b5 Nd8) e5 - Black is fine. White would want his knight on e2, so is punished for his first move ...  Wink

The KIA is not effective against the Dutch. White should rather transpose to the main lines with d4.


I agree. If I see my opponent plays the Dutch, I can play 1. e4  Wink

Transposing into a c4/d3 setup for White is OK vs Dutch too, no  Huh

Expanding the discussion somewhat...

How about the combination of KIA and Reti?

Play Davies' lines against 1.Nf3 d5 2.c4, then play a KIA against anything else other than 1...d5. OK, I guess that means 1.Nf3 c5 (or 1...e6/c6 etc) 2.e4 and you are in a Sicilian.

Any thoughts?

After 1.g3 d5 2.Bg2 c6 3.f4, Black should achieve a good game with 3...Bg7 4.Nf3 Qb6!? followed by ...Nh6, ...0-0, ...Nd7 and ...e5 (depending on White's reply). Still, if Black isn't aware of this method of utilising ...c6 then the Polar Bear isn't so easy to counter.


I assume you mean 1.g3 d5 2.Bg2 c6 3.f4 g6 4.Nf3 Qb6 5.d3 Bg7 (I don't see why we should give Black a free move). The most promising seems to be 6.Nc3. Gonzalez-Teran, Santa Clara, shows a quite aggressive approach by White.

of course 1.e4 d5, or 1.g3 f5 are not bad for White for exemple, it's just no KIA today !

If Black tries to reach a Slav White may try the Leningrad Bird.

After 1.g3 d5 2.Bg2 c6 3.f4, Black should achieve a good game with 3...Bg7 4.Nf3 Qb6!? followed by ...Nh6, ...0-0, ...Nd7 and ...e5 (depending on White's reply). Still, if Black isn't aware of this method of utilising ...c6 then the Polar Bear isn't so easy to counter.

Not if Black choses an IZ or Leningrad.
I assume that PMagique meant that the KIA is not such a good idea against the Dutch. If yes I completely agree. 1.g3 f5 2.d4 of course leads to all kind of main lines.
If Black tries to reach a Slav White may try the Leningrad Bird.

I doubt 1...f5 is the critical response to 1. g3. White can just play 2. c4. Don't most people think the Dutch is less good vs. the English, since White can angle for e4 much easier?

All more orders to reach the KIA have drawbacks in my opinion :
1.e4 d5!? no KIA
1.Nf3 Nf6 2.g3 b6 3.Bg2 Bb7 4.0-0 e6 5.d3 d5! 6.Nbd2 Nbd7
1.g3 f5!?

One idea behind 1.g3 is to meet 1...c5 2.Bg2 Nc6 with 3.e4!, reaching a Closed Sicilian where White can still use his c-pawn (mostly to protect the d4 square but occasionally also to play c4). This can not as safely be done with the 1.e4 c5 2.g3 move-order as then 2...d5!? can be annoying.

1. g3 also reserves the right for White to play some reversed variations not possible other wise, for instance 1. g3 e5 2. Nf3!? or 1. g3 e5 2. Bg2 d5 3. Nf3!?
Also, I'd hazard a guess that you'll probably run into more reversed Grunfelds and Pirc's after 1. g3, since people are more likely to play ...e5 and ...d5 against this way than play something like 1...Nc6 and 2...e5 against 1. Nf3. 

PS - Man, I missed my post before this one - God Member! WHOO!

I think it depends on what else you play with White. 

If you also play 1. e4 to transpose into the KIA, then 1. Nf3 fits better.

1. Nf3 also feints that you might play a Reti, or meet 1. ...d5 with 2. d4.

If you also play the English (e.g. Dynamic English), then g3 fits better.

If you know your oppenent plays the d5/c6/Nf6/Bf5 set up, then the g3 move order saves a tempo over Nf3. This is a minor nuance though.

Another consideration is how you might meet 1. ...f5

I think 1. Nf3 is more popular due to the tie in with 1. e4, and the desire to restrain e5. So also descide how you would meet 1. ...Nc6, or 1. ...d5 2. g3 Nc6 

1. g3 also gives some options with an early f4, but I've not been a fan of those.

The only downside from what I can see to 1. g3 is that set-ups involving ...c6 (Slavs) are much more effective than against 1. Nf3, because white retains the option of the main line Slav with 1. Nf3.

Obviously 1. g3 e5 is an extra option, but 2. c4 gives people an English variant that they may like anyway. I guess 1. g3 also cuts out 1...b6, but that hardly seems critical. The choices after 1...c5 aren't that special, either.

I toyed around with the idea of opening with 1. g3 occasionally, but there were more downsides than advantages compared to 1. Nf3.  Undecided

I had a quick question: What extra possibilities does White have with 1.g3 compared to 1.Nf3, and what extra possibilities does Black have against 1.g3? Most importantly, how strong are these extra options?
