5. c4

I often like to have both Bishops "fianchetto'd" on the same side like this, but usually on the Queen side
11. Nb1c3 c6 12. Ra1c1 Nb8d7
I also like to keep my opponent guessing where I will be castling my King.... makes for some interesting games

Just aiming to open the centre up, however White may be gaining tempo with 15.dxc5 Nxc5 16.Nxc5 Qxc5 17.Qa4+
15. Bg3f2 O-O 16. e5
? Continued neglect of piece development will soon cost White... 16.Be2 (as per move 5) was better
16... dxe5 17. dxe5
? This can simply be taken, whereas dxc5 could not... now the e-file has been fully opened at the White King's peril
17... Nd7xe5 18. Bf2xc5
(note, if instead Nxc5 then Qxb2 is good)
18... Qb6e6 19. Ke1f2 Ra8d8
Always wise to bring all available resources into an attack
20. Qd1e1 Bg6d3
White cannot capture due to the Knight fork
