So I thought about to play 4. ...Qc7: it's surprising, that there are nearly no sources to this line except of an old book by Burgess (year +-2000).
Thanks Gewgaw - interesting this 4... Qc7, probably the idea is to play a Kan 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Qc7 5. Be2 a6. But I wonder if there must be some drawback to this move order .. perhaps involving Nb5.
I'm confused about Gewgaw's comment; I had assumed he meant 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Qc7, a line which I have one fond memory of: I played a really nice game and beat a FM after 5. c4 Nf6 6. Nc3 Nxe4 7. Nxe4 Qe5, though of course it had nothing to do with the opening.
For that game I altered my usual 2...e6 move order because I didn't want to face 5.Nb5 d6 6.Bf4, which my opponent had played against me previously. I don't understand Gewgaw's comment though, as I don't think Black has any particularly great deviations if White develops in classical fashion with 5.Nc3, 6.Be2, 7.0-0, etc.
Regarding the Kan move order, in my mind one of the big "problems" (at least in a philosophical sense) is what to do after 4...a6 5.Nc3 Qc7 6.Be2. Again you have to choose between the 8...Bb4 line, 8...Be7 line, or one of the 7...b5 or 8...b5 lines, all mentioned above. The only uniquely "Kan" way of playing that I'm aware of is the immediate 6...b5 with the idea of NOT playing ...Nc6 any time soon, but I've never entirely trusted those lines and always transposed to a Taimanov when my Kan games have gone this way. Of course Black can play 5...b5 instead of 5...Qc7 there, but after 6.Bd3 Qb6 7.Nf3! I've never been very comfortable with the Black pieces.
It's all a bit mess, but I refrained from saying "Paulsen" anywhere above to minimize the confusion
