15.Re1 or 15.Re2, both enabling Nc5 to be answered with b4.

Years later I understand but Marin on page 326 of his second volume of the English gives 19.Qb3 e5 20.Nd2 intending a white plan of c5, Nc4, Rb6 and Nd6.
Following Tony's line 19 Qb3 Nc7 20 Re5 Qd6 21 Re4 e5 can white play 22.c5 with Nd2 to follow ? Should queens come off, f4 becomes possible with b7 perhaps being vulnerable afterwards, d4 becoming weak and Nc4 / d6.

Tony, this looks familiar somehow. Is it in Tal's own book of his games, possibly?

Yes, I thought so, too, but couldn't find it in the index (I have the RHM book).

Perhaps 10...Re8! intending e5 at some point is just strong?

Yes, this is my current conclusion, too.

Nunns Chess Openings also gives 15.Rb1!+= (page 24, note 9 - btw. under the topic "English Opening") without further comments.

Following Tonys line to 18...Na6 I tried to find a way where white may sac the exchange on b7 and then keeps the connected pawns but failed (Mr. Byte showed me clearly).

There is also a weird comp-line putting the queen on e1 which I dont believe (19.Qe1 Nxb4 20.Rxb4 Qa5 21.Bc3 (argh))  in and finally we can try to play c5 (instead of Qb3 for example), but this grants the d5-square to blacks knight and should be fine for him.

After all the rook looks (or is?) misplaced and is pushed back - the tide is rolling for black, bad news for white. I would certainly prefer black after Tonys 15...Nc5! which may even lead to a ?! for 15.Rb5 in the future. All magicans have their tricks - unfortunatly we cant ask Tal anymore Sad

Perhaps 10...Re8! intending e5 at some point is just strong?

One problem after your line being that white probably can't get away with f2-f4, because after Qxb4 the white queen is hanging on b3, however even putting the queen on d2, doesn't seem to help, at first I thought
19. Qd2 Nc7 20. Re5 Qd6 21. Re1 e5 22. f4 exf4 23. Rxe8 Nxe8 24. c5 or the like might be fine, but as my computer then showed me black can imrpove with
22...Qxb4 23. fxe5 Bf5 24.Bxd4 (24. Rd1 Qb3) 24... Bxd3 25. Rc1 Ne6 26. Qxd3 Nxd4 27. Be4 g6 or 23. Qxb4 Bxb4 24. Rxe5 Rxe5 25. fxe5 Bf5, both of which seem better for black.

Um, maybe white should try for a draw with 20.Ra5 Na6 21.Rb5?

As part of my research for the DW book I was looking at the Réti line 1 c4 e6 2 Nf3 d5 3 g3 Nf6 4 Bg2 Be7 5 0–0 0–0 6 b3 c5 7 e3 Nc6 8 Bb2 d4 9 exd4 cxd4 10 Re1 Re8 11 a3 a5 12 d3 Bf8 13 Ne5 Nxe5 14 Rxe5 Nd7 15 Rb5 which is supposed to be good for White, but hit a major snag: 15...Nc5!:

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

which forces 16 b4 axb4 17 axb4 Rxa1 18 Bxa1 Na6 19 Qb3 Nc7 20 Re5 Qd6 21 Re4 e5 with a Black advantage, as played in some obscure Russian game. None of the Réti books I have even mention this, preferring to concentrate on 15...e5 ("the consistent follow-up" - Dunnington) which leads to two nice wins, by Tal and Miles.
Does anyone know what is wrong with this line for Black? Undecided
