It illustrates how the active pieces of the side with the IQP can spring to life. } 1. c4 c6 2. e4 d5 3. exd5 Nf6 4. Nc3 cxd5 5. cxd5 Nxd5 { Back to that question of - how do we end up with IQPs? Both sides were fighting for control of the center. Thanks to the first-move advantage white will be the side that ends up with a pawn in the center. } 6. Nf3 e6 7. Bc4 Nc6 8. O-O Be7 9. d4 O-O 10. Re1 Nf6 { Another common position, reached hundreds of times. } 11. a3 a6 (11... b6 { This is preferable. Black wants to develop their bishop to b7, but a6-b5 is too slow. } 12. Ba2 Bb7 { White scores quite well from this position as well, but the engine prefers it at least. }) 12. Ba2 { This a3-Ba2 maneuver is a common one. The bishop will live on that strong diagonal, targeting the black king, basically forever. } 12... b5 { A common move, but not a very good one, as we'll see. } (12... Re8) 13. d5 { A thematic break! White uses the isolated pawn to open the position, while they enjoy a lead in development. The a6-b5 sequence was too slow. Incidentally, this position is in the Lichess masters db 24 times - white scores 14 wins, 9 draws, and 1 loss. } 13... exd5 14. Nxd5 Nxd5 15. Qxd5 Bb7 (15... Qxd5 { Not Qxd5, when... } 16. Bxd5 { The knight is hanging, but it's the only defender of the e7 bishop! The slight lead in development -- rook on the open e-file -- makes all the difference. }) 16. Qh5 Qc7 { The engine prefers Qd6, though that scores terribly. White is practically winning. } (16... Qd6) 17. Bg5 Bxg5 18. Nxg5 h6 19. Re3 Na5 (19... Ne5 { This is the only move that doesn't lose on the spot, but after the nice tactical shot... } 20. Ne6 fxe6 21. Rxe5 Kh8 22. Rxe6 { ... white is simply up a pawn, and will almost certainly win. }) 20. Qg6 hxg5 21. Rh3 Rfc8 22. Re1 { 1-0 Black resigns. } 1-0
