In the US I think 4 ball carom is played more than straight rail -- I've seen a lot of 'korean' 4 ball being played but I can hardly ever remember seeing anyone playing straight rail.
So in this time and place usually seems correct
I was having ticky problems in cases where the ball was more than a couple of ball widths from the cushion and Dave Gross aka @12squared showed me a way to determine the proper aiming point. Unfortunately I'm old and haven't been able to play for a couple of years and I forgot what it was, so...
It was a nice shot but even a putzer like me has made that shot many times, so I think calling it brilliant because it was made by a woman seems a little patronizing, to me.
