How could I have extracted an opening advantage in this Owen's defence game? I played as white against Owen's defence from black, which is seen as being quite dubious. After 21 moves, we agreed to a draw.

My question is, how could white have extracted an opening edge here?

O-O h6 {This was the first move that surprised me, so I chose 8. Nbd2 and 9. Re2 simply because they were thematic, as I couldn't see a way to punish 7...h6} 8. Nbd2 d6 9. Re1 Nbd7 10. e5 {I'm not too sure about this move, but my plan was to make a few trades to play Nd2-f3 to liberate the dark square bishop. I also thought the open d-file could be useful} dxe5 11.

Black's opening play doesn't look good. This is more passive and dubious than a normal Owen's.

The suggestion of 10. Nf1 followed by 11. Ng3 is a good one and should give white a nice advantage.

But I believe black should be punished harder for their passive play. Perhaps 8. e5 Nd5 9. a3!?.

Black has to worry about the knight on d5 getting trapped. After 9... c5 10. c4 Nc7 11. dxc5 bxc5 12. Nc3, white obtains a better position than they usually get in Owen's.

Black's kingside looks really weak.
