When to call intentional fous

[Back In The Saddle]

I'm a pseudo new guy--back after 10 years of not officiating. I've done two games now, in a local church league (about rec league level of play, using high school rules). I have not had the benefit of any association training or veterans to work with for a decade. So, I was delighted to find this forum and look forward to learning a lot from you all!

Last night I worked a boys game. The home team was up by about 6 points near the end of the game. The inevitable fouling began, the visiting team trying to stop the clock and regain possession. They were pretty obvious about it.

Trying to keep the game under control, I called a couple of intentional fouls when the visiting team's player got more physical about fouling than I like. And I called some obviously intentional fouls as regular fouls, when they weren't overly physical about it.

At the time I felt like I was using the intentional foul rule to keep the rough play under control. Today it just feels like I was being inconsistent. So, my question: when do you call the intentional foul?
