That 'take out' fram shot was a very, very poor desperation shot that happened to work out.
One pocket has evolved and aggression is good, but this isn't advisable.
With certain caveats, I disagree.
Sometimes, when your opponent has their hole surrounded, you just have to say "fire in hole" and blast away. The first caveat is that you have to try and control whitey, either swinging around the table or doing a force follow toward the udder guy's hole. I have had this done to me so many times that I am now a believer.
The second caveat being that you need to be able to judge your speed carefully, so balls don't travel cross table and go back to your opponents's side.
The last caveat is knowing who you're playing. If I'm playing a guy who is likely to only going to get a few v. a guy who is going to run out, I may very well throw my skirt up in the air, blast away and say, "Come get me boys!" Depending on your opponent, you do this, he just gets a few, you have balls on your side... and it is not so bad.
We get so used to watching the pros on streams and DVDs we think the local yokel is going to be on us like Frost. Not so, most times.
