Does Size Matter: 6,7ft vs 9ft Tables. Dr. Dave Request

Just ask any typical bar player that bangs balls on a 7 foot table to gamble with you on a 9 foot table and you will get some answers to your questions.

Kevin

The key word in your post is "typical bar player". Is he playing a "typical 9-foot table banger"? Is he actually a "gambler"?

There are people who "specialize" in each size of table. A good bar table player probably doesn't want to play a good 9-foot player on a 9-footer, while the 9-foot player probably doesn't want to play the other guy on the 7-footer. Everything is somewhat relevant. If you have a guy who can shoot a .XXX percentage on a particular size table, a guy who shoots a lesser percentage on that size table isn't going to beat them. I was the highest rated bar table player in the leagues when I lived in Grand Forks, ND., yet I only practiced on 9-foot tables. They guy who owned the pool hall and all his employees and team mates didn't have as high a rating as me. The full-time bar table players didn't have a rating as high as mine.

When I played almost exclusively on bar tables for a while, there were PLENTY of big table players that could not beat me on the bar table and I could hang with them on the big table. As much as I think it is easier for me to run packages on the bar table, I think I must maintain "tighter" control of the cue ball on the bar table in order to avoid bumping into balls all the time and messing up the layouts. If you get an open break on a 9-footer, you have a bit more room for error and getting around "trouble" spots.

People will argue it both ways and nobody is necessarily ALL right.

All I know is that at one time there was way more money to be made in the bars than you could ever hope to make in most pool halls. The people in the pool halls sat around all day asking and waiting for the "world" in spots before they would feel froggy enough to jump on the table for money.

Rather than listen to their stories and propositions all day, I would just hit the bars and find whatever action was available. Back in the day, the bars were full of idiots and occasionally some real good players who called their bar "home" and they always tried to act like "king of the hill" or "cock of the walk". If you could actually play well, it wasn't too hard to go into these places and take all their money, as long as you had some sense of composure and acted somewhat cool. It also was to your advantage to have some kind of "spidey sense" so you could pick up the "vibe" when it was time to take your cash and get the hell out of Dodge before all Hell broke loose. I almost always travelled alone and I've had that happen on several occasions and it isn't necessarily fun.

I used to love going into the Mexican bars in Riverside CA and playing. There was one place called "Joe's" (f my memory serves me correctly) and they always had people playing for money (maybe not high stakes by some people's standards, but actual real dollars nonetheless). For whatever reason, there always seemed to be an abundance of Mexican bar table players compared to the lesser number I saw playing on the big tables in the pool halls. You could go in the place, act normal, drink a couple beers or more and leave with several hundred dollars on most occasions if you hit the place at the right time. There was another place on Magnolia Boulevard that was a biker bar called the "Golden Wheel" (or something like that) where you could find some action, if you could fade the crowd...ALL BIKERS. I shot pool with some real gnarly looking characters in that place, but I never tried to hustle anybody. I would just challenge the table and go "all out"...I never tried to hide my speed because if they "thought" you were "hustiling" them, you probably was not going to leave the bar standing up.

Bar table players are like Rodney Dangerfield...they don't get any respect. There are some bar table players that play "jam up" on any size table...they just "specialize" in the smaller table.

Aloha.

This question(s) is actually for anyone handy with graphics and/ or math.

1. Can the difficulty level of playing on a particular size table, as compared to a larger table, be expressed as a percentage?

Examp.: "Based on size alone, Bobs 9ft gold crown is XX% harder to play on than Fred's 7ft bar box."

YES

2. I'd also like to see a graphic of a 9ft table showing the " red zone " along the sternum of the playing surface that illustrates the extra (rectangle of) play area gained in the center of a 9ft table, compared to a 6 or 7 ft table.

AT THE RISK OF BEING BANNED, I RESPECTFULLY DECLINE MY INSERTION OF JPG


3. From within that relatively small area ( red zone) in the center of the table, some shots on a 9ft table will be physically longer in distance than the same shot on a 6 or 7 foot table. Can a percentage be established to represent how many balls from a given game would fall into (or be affected by ?) the red zone at some point ?

Thanks in advance for humoring my request

see above in CAPS
sometimes, 1/2 of an inch, can make ALL-LLLL the difference in the world....
:cool:
 
You can't go by size alone to compare tables. The extra distance of a 9' compared to a 7' really only means that your accuracy has to be greater given the same size pockets.

If you reduce the size of the pockets on the smaller table, you can get a closer comparison to equality. However, there will always be some difference no matter the size pockets because of distance and how that relates to spin on the cb and ob.

Right now, the only real comparisons I have seen are with pocket size. I don't think there has been a study in the way you suggest. It would be interesting to see one done, and also that compared with pocket sizes.

I would assume he means, "all other things equal", what would the difference be with a bigger table.
 
I play almost exclusively on bar boxes. I will say this. In my opinion big tables are much harder. If almost every shot is longer and more difficult to make. It makes position that much harder. So on a 9ft table you have to make a harder shot. Which means less confidence. Which leads to more misses and bad position. On a bar box the shots are easier but position may be more congested. However because the shots are easier you can focus more on position with more confidence in making the shot. Hope that made sense.
 
Here is the link to mobile friendly page I created which calculates TDF based on Dr. Dave's method

That's awesome. Thanks for doing that.

FYI, I've added links (with credit to you) on the Table Difficulty Factor (TDF) resource page and AZB TDF thread.

Thanks again,
Dave
Isaac,

FYI, per the recent posts in the TDF thread (e.g., here), your tool seems to have several bugs/errors. Please fix them when you get a chance and let us know (in the TDF thread) when the tool is working properly. FYI, all the equations necessary for your tool can be found in the Table Difficulty Factor (TDF) Excel spreadsheet calculator. Hopefully, that will help you find and fix the errors.

Thank you,
Dave
