A1 and B2 are running down the court in transition, A1 elbows B2. What's the call? Peace

More info, needed.

Was it a nudge, a hook/swim move, or a shot to the chops?

No shot to the chops, just an elbow to the side, get off of me type......

WHTBT - would have to be there.

I was just wondering, I called a tech but was informed later by another ref that you can't give a live tech, should have been an intentional. What's your take?

If the contact constitutes a foul, then it's a personal foul, not an technical foul. Contact fouls during a live ball are personal fouls.

So an elbow to the side is just a foul. What foul do you call?

You could have a personal foul, a player control foul, an intentional foul, or a flagrant foul.

Since you called it a tech, I'd lean toward intentional or flagrant, but since it was below the shoulders an intentional would probably do.

If it's, "Get off me!" and the motion was intended to be with the arm, but the elbow got there first, I'd call it a personal foul. If the foul-er aimed, cocked and fired, I'd call intentional or flagrant.

It doesn't really matter. The important thing is that you call it a personal foul. I'd probably call it illegal use of hands or possibly a push but again, that's not the important thing here.
