Hello. I'm a beginner; I have played around 12 Go games in my life. I have a serious interest in learning Go to a decent level (I know than that's very subjective). I'm asking for recommendations as for the time settings (for the Fischer system) that you'd recommend to play in size 9, 13 and 19 for real time matches (Lasting a single continuous playing period). I'm aware that it's a compromise. Longer times allow for more thinking but can become tiresome at the end, decreasing quality of play, and fewer games can be played assuming that there is always people willing to play. I currently play mostly on size 13. Do you think that I should switch to size 19 already?. What are the differences? I suppose that it will be mostly increased match duration, emphasis on influence at the opening, and a more strategical, less tactical game game until the endgame.

Regards.
