Why do you like win by 2? For the record, I'm not a huge fan of it because I think if you choose a number to race to that shouldn't change. I also don't think it would be a good idea for larger tournaments (if tournaments at all) because you no longer have some control over the timing of the matches.
You're right about the time, buddy playing sigel played a the match in a race to 11 win by two. Final score was 23-21. One of the most exciting matches I have ever seen.
It was one of those Grady tournaments. Grady often liked to tinker with rules. Truth is, when it comes to rules by trying them out you find the strengths and flaws.
The win by 2 was partially a way I ran monthly tournaments for several years. It works good.
The complete format was, race to 6 two out of three sets. If it went to the third set you had to win by 2.
The players loved it. It became a popular tournament.
The win by 2 thing for me is, once two players reach hill hill, they are both winners.
It is a shame for a players to play a tough match to have it decided by one game.
Also in pool there are no real set rules. Myself like Grady put on tournaments and often made up our own rules. You know pretty quick what works and what doesn't.
I played in one Grady tournament where he had us calling all balls (9 ball) 9 on the break spotted and you keep shooting.
Untill you actually play by various rules you don't really know how it will work out.
