5. e4 Nxc3 6. bc c5 ! 7. Nf3 cd 8. cd Bb4 (8... Nc6 !? This was played by Geoff v Kev - comments follow :  Well Bb4 check exchanging pieces is a popular way of playing this, but there is no rush for me. 9. a3 Yes now White has in fact lost a move preventing the check. This  has been played 31 out of 228 times, but too slow for me. Why is White scared of Bb4 + ? Kev tends to over-elaborate with positional prophylaxis - type moves occasionally. (9. Bc4 b5  trick is available.) 9... Be7

Qd8 The point of Black's play - the d-pawn and a-pawn are threatened. 15. Bc1 White appears to have gone backwards to where he was on move ten. Qa5 Now Black forces the Queen swap. 16. Qd2 Qxd2 17. Kxd2 f5 An important blow against the White centre. White is still under pressure. 18. e5 (18. ef Rxf5 Black has good play.) 18... Rd8 19.
