Eclectico, the reportoire you give is asking for unneeded complications. Against the Bird, the save move order to develop is d5 - g6 - Bg7 - Nf6 and only then c5 - Nc6. If you first play d5 - c5 - Nc6, you give white the extra option of Bb5, which can be very tricky in some lines, and Benko type of pawn sacrifices in the Bird Leningrad.
In the Reti, I think this lines is very dangerous in your reportoire:
1. Nf3 d5 2. c4 d4 3. g3 c5 4. b4 cxb4 5. a3 bxa3 6. Bxa3
The idea behind playing an early c5 is for transpositional convienence. For example
1.b3 d5 2. Bb2 c5 is my proposed anti-larsen plan. but here 3.f4 is a Bird variant where i have c5 input already. Another line is 1.d4 d5 2.e3 Nf6 3.f4 where i play the queen's gambit reversed against the stonewall with 3...c5.
I wanted to include early an early c5 against the bird before declaring my intention to fianchetto. What do you think of the move order d5,c5,Nf6,g6,Bg7 and only Nc6 after white has moved his king's bishop?
By the way, my only reference source besides MCO are the dutch defense chapters of "opening for white - Kramnik". Do most of the ideas for white against the dutch make sense in the bird?
Regarding the Reti line you give:
I would play 4...Nf6 declining the gambit (at least untill i'm better developed). The Benko gambit declined approach is presented for the white player in Grivas' excellent "beating the fianchetto defenses".
