I didn't realize that I was in fact winning in this position, seeing only White's good Queen-Rook battery and near-passed e-pawn (I was thinking of it as a passed pawn instead of seeing it was really mine for the taking... I feared ...exd4 would be followed with White e5.)
So, thinking I was still losing instead of winning I felt good that I had a forced draw with 19. ...Qf3 and if Oscar hadn't agreed to the draw that's what I would have done to get a certain result.
This was my last game in this Quad tournament, and by choosing the draw I received 2nd place in the section. Had I pressed and won I would have tied for 1st. But still, a fun game with back-and-forths for who was winning.
