Sorry, but in my mind that sounds like dirty pool.
I remember a great player once told me, pool is different then any other sport, if you're good enough your opponent will never get the chance to even play.
I think the bottom line is that safeties are an extremely important aspect of the game, but if you are using them as either a crutch or a way to frustrate your opponent you are only hurting yourself in the long term.
just my two cents'
p.s.
Me, or anyone who has played 3 cushion, or knows the diamonds is going to hit that ball 90% of the time
so you better make it a dead nuts safe
As much as I hate to say it, it's part of the game. One way or another, someone's will to win is crushed. Rarely do both people have the will and desire to win (belief in themselves) all the way to the very end.
Often it just happens as a result of good play by one player. A player makes some great shots, a tough out, or runs a couple racks and the other guy sinks mentally.
Doing it with a safety is intentional, a little sleazy, but if a player falls for it or loses their mental game - they deserve to lose. They possess a bad attitude. My attitude is to be absolutely happy just to be at the table, even if in a lock safety situation. Why? BECAUSE I CAN'T WIN FROM THE CHAIR. I often play people who, if they're at the table - it means I've lost. If I get to get on the table, it is a privilege that I probably did not earn, so make the best of it. Look, I'm no fool - the odds are low. But if you can take your tip and hit the CB because it's you who is at the table, anything can happen. And low percentage is better than no percentage (being in the chair).
Because players don't have that attitude, and feel entitled to having their inning at the table begin with a super easy road map layout for a run, they can get down if they are hooked. Well, that is a game weakness of the mental sort and they deserve to lose.
The downside to doing this is becoming dependent on it. It only works against weaker players anyway. As stronger players generally also have stronger mental games and attitudes. Eventually, that safety abuser or person looking to break the opponent's will, will run into a player where these kinds of tactics don't phase them one bit. In fact, it might encourage the other player to play stronger. I've seen it backfire, the opponent makes a great kick, gets super confident and gets in the zone or dead-stroke then proceeds to clobber the guy who played safe.
That is why I said in my earlier posts in this thread, it's generally not a good idea to EVER turn the table over. Which is why better players tend to opt more for offensive options, than risk the unknown of the safe by putting matters into their opponent's hands.
Now, even if they don't kick it in or hit it, does it matter? If that sort of thing isn't rattling your opponent's psyche, why bother with it? Just wasting time, and opening yourself up to risk.
Overall, the safety for the purpose of annoyance is generally a waste of time. But it does work well on banger and bar league type players. Then again, they play poorly already - is it necessary to break their will to win, in order to win?
