After 7.Be2 dxc4 8.Bxc4 b5 you makes a real -if still not decisive- mistake with 9.Be2?! Much better was 9.Bd3, to keep the bishop in the important diagonal b1-h7 from which it could eventually participate in aggressive action in the kingside or the centre. Also (9.Bd3!) after an eventual ...c4 the bishop would go to c2, from where it would defend the weak square b3 ( a consideration surely kept you preocuppied during the game). Now (9.Be2?!) we can agree that Black has got full equality. After the interesting if risky 10...c4 (much in the style of late XIX century master chess), 11.b3? has been a significant mistake. One has to realize that (10...c4) White's chances are in the centre and kingside, which calls for the immediate 11.e4!? In case of 11...Na5 you could play 12.e5, with a complex struggle. After 11.b3? cxb3 12.Qxb3 Na5 Black has a clear superiority, as its pieces (Na5, Bb7, Nf6, Rc8) control the centre and the queenside. See how you have opened the game precisely where it's your opponent who profits from that. Two minor but suggestive details: your "a" pawn is now isolated, and Black has vacated the valuable square c4. Everything suggests that 11.b3? has been a positional blunder. When one gets into serious trouble, it is only natural that we overestimate our chances in a tactical operation, as you made by means of the faulty combination of 17.Nxb5. As you see, commenting a game against List is much easier than playing the monster :) Telmo
