Firstly to the sportspersons aspect, regardless of the opponent and the quality or lack thereof regarding their shot making you should always shake hands at the end of the game. I remember back in 1995 I bowled a tournament at Clayfield and in match play I was bowling against Ian Bradford and I threw 7 Brooklyn strikes in a row to beat him, and while he wasn't happy (but who would be to lose that way), he was still very gracious shook my hand and gave me some words of encouragement which being a young guy meant heaps coming from a legend of the game.
Now as far as Brooklyn strikes go, I have always maintained that they should be a 7/, I mean bowling is the only accuracy based sport where you are actually rewarded for making bad shots. There is nothing worse than bowling a tournament and you smash the pocket for a 10,7,8 or 9 pin while your opponent misses their mark by 5 boards and goes Brooklyn for a strike. But I figure that you just need to concentrate on the things you can control and keep making great shots and hope the pins drop for you.
Although for anyone who has left a ringing 7,10, or 8 pin for 299, there is nothing more soul destroying than seeing someone shank their twelfth shot and go Brooklyn or through the beak and drop all 10 pins for a 300. But I guess that is what keeps us coming back.
