wow!
ian, seems like you are very into the sport then to actually attend
this type of courses. I for one dun even know if these courses
exists 
harmy, deamon, ian,
I dun mean playing cheap to distract your opponent, but bowling in
such a way that it creates pressure on the opponent.
One the coaches for national youth said it is important to be
aggressive in bowling. Dun really understand then and there what he
meant by being aggressive. Now I realised its a ...wat word to use
(scratch head)...certain "aura" that the aggressive player
projects. This aura sometimes forces a "I will win", impression on
the opponent. 
Another type of mentality I came to realise is the Happy-go-lucky
(h-g-l) type. The h-g-l bolwer just deliveries and get a lucky
strike (not the cigarette) and smile. Then you would wonder, what
the hell! And, on your frame, u leave a miserable pin 10. 
The last and final mentality is the NEVER-SAY-DIE attitude. You
concentrate on your game. If you're lagging, you stay close, if you
winning, show him he have no chance of catching up. Easy to say,
hard to follow! haha!! 
....hmmm.....what deamon said abt just concentrating on your own
game....I did it successfully once or twice. Remember shooting a
6-bagger in one of them.
Just to share an extract I read in a book by an ex-pba
player:
"When you throw a bunch of keys into the air, and u catch it, at
that instant, your entire mind is just focuing on catching the keys
which are dropping. None of the concentration is diverted to other
places. There is only one goal: Catching the keys. From the time u
stepped onto the approach, to the time u release the ball, if your
mind is as that like catching the bunch of keys, totally focus on
one thing, you will win." quote pba player, forgot who liao.
By another "the most distracting thing that deters me from making
the ball do what I want it to do is the mind." quote a female coach
somewhere in US.
