Well thought more would give it a try but oh well here are the answers
--------------------------------------------------------------------------------

ANSWERS

Scoring the test is simple. Give yourself 10 points for every 'D' answer, 0 for anything else. Trouble is, any score less than 100 is a failing score. A professional-level sports bettor must know the answer to all the questions or sooner or later he'll be out of business.

QUESTION 1: When laying 11 to win 10, approximately how much vigorish is paid by losing bettors?
The answer is D...It's a loaded question. Losers don't pay any vigorish at all. Vigorish is always deducted from winnings.
Here's a brief explanation: If two bettors were to bet $110 against one another without using the services of a bookmaker, the winner would walk away with $220. The loser would lose whatever he put at risk. (After all, he lost the bet.) Using a bookmaker, the winner walks away with only $210...The winner was charged 9.1 percent of his winnings by the bookmaker. (Casino games such as craps, roulette, blackjack, slots, etc., work the same way. Winners receive less than the "fair" amount.) Check our article, A Crash Course In Vigorish - And It's Not 4.55%

QUESTION 2: Against money lines, bookmakers make...
The answer is D...Against money lines, bookmakers make nothing at all when favorites win. They make a profit only when underdogs win.
Here's a brief explanation: If a favorite-bettor lays $150 to win $100 and a dog-bettor lays $100 to win $140 on the same proposition, the bookmaker receives a total of $250 from the two bettors. If the favorite wins, the bookmaker returns the $150 risked by the favorite-bettor plus the $100 won...The bookmaker keeps nothing of the $250. If the underdog wins, the bookmaker returns the $100 risked by the dog-bettor plus the $140 won...The bookmaker keeps $10 of the $250 risked by the two bettors. Bookmakers are usually cheering for the underdog.

QUESTION 3: A 3-bet parlay paying 6-to-1 has vigorish costs...
The answer is D...Vigorish costs for a 3-bet parlay that pays 6-to-1 are slightly lower than the cost of three individual bets wherein the bettor lays 11 to win ten.
Here's a brief explanation: If a bettor risks $100 to win $90.90 on a single bet, and wins, he then has $190.90 ...If he risks the whole $190.90 to win $173.50 on a second bet, and wins, he then has $364.40...If he risks the whole $364.40 to win $331.30 on a third bet, and wins, he ends up with $695.70. If he risked the same original $100 on a 3-bet parlay at 6-to-1, and wins all three bets, he ends up with $700. The vigorish cost is actually about 4.35 percent, rather than the 4.55% cost of laying 11 to win ten. (But that's NOT why bookmakers don't advertise parlay bets..Parlay betting can protect your downside risk, and it is not in the bookmaker's best interest for you to protect your downside risk.)

QUESTION 4: Professional-level sports bettors expect to win...
The answer is D...Full time gamblers expect to win fewer than 60% of those bets wherein they lay 11 to win ten. (In fact, a long term winning percentage of 60% or more is actually too high!)... Check our article, Winning Percentages, for a fuller explanation.)

QUESTION 5: On any single bet, professional-level sports bettors rarely risk more than...
The answer is D...Professional-level bettors rarely risk more than 2% of their bankroll; usually much less. Professionalism demands that sports betting be regarded as a business, NOT a heart-stopping thrill ride.

QUESTION 6: When laying 12 to win 10, winnings are shorted by approximately...
The answer is D...When laying 12 to win 10, winnings are shorted by 16.67 percent.
Here's a brief explanation: If two bettors risked $120 against one another without using the services of a bookmaker, the winner would walk away with $240; - the $120 he put at risk, plus the $120 he won. Laying $120 to win $100, the winner walks away with only $220...The $120 he 'should' have won was shorted by $20...(16.67 percent).

QUESTION 7: With a 60% winning expectation-per-bet, the odds against going 4-0 are...
The answer is D....0.6 x 0.6 x 0.6 x 0.6 = 0.1296 (7.7-to-one).

QUESTION 8: In football, that stat which best parallels a team's won-lost record is...
The answer is D...In football, that stat which correlates best with a team's won-lost record is the stat concerning rushing yards.

QUESTION 9: Generally, the most significant football injury to a pro gambler happens to the...
The answer is D...The most significant football injury to a professional handicapper is to the center. The center is a key part of the offense, but his injury rarely effects the pointspread. Pointspreads tend to compensate for the other listed injuries.

QUESTION 10: The money management system most widely used by professional gamblers is...
The answer is D...Genuine experts understand that progressive betting schemes are strictly for suckers. The size of your bets cannot be used as a pry-bar to earn more than you deserve. In fact, professional-level sports bettors strive to keep their bets at the same size. Having a slight advantage on every bet, the goal is to wear down your opponent. Note that varying the size of your bets against roulette and craps gives you your best chance of winning against those games because the odds are against you! The opposite is true against sports betting - so long as you've done your homework! How could the same tactic work in both scenarios? Blackjack players often espouse using different-sized bets against sports, but that's wrong. Note that against blackjack they ALWAYS advise using the SAME size bet against a PARTICULAR positive count. When the deck is giving them more than a 4 percent advantage, you can bet they ALWAYS advise risking the maximum bet. Against sports, we presume to ALWAYS have at least a 4 percent advantage, therefore our bet size never changes. Unlike blackjack, the "deck" is never against us, so we don't have to worry about betting a "minimum" bet; - when the odds are against you in sports you don't have to bet at all!

do you agree with all of them?

The test is quite silly but I'll give some comments anyway...

Q1: Correct answer = E: depends on how much of the vig you attribute to winners and how much to losers. Real sports bettors and bookmakers don't care. They are only interested in total vig.

Q2: B, in general, but by no means always. Serious bettors and bookies know that important decisions are situation-specific, so like Q1 this question has little more than recreational value.

Q3: D, agreed

Q4: E: none of the above...it could be as low as 45% for a dog specialist or over 65% for a fav specialist. And for ATS picks, 55% lifetime is a stretch for just about anyone. 52-54% is more like it for most pros.

Q5: D, agreed

Q6: D, agreed, but the question is stupid because everyone knows what laying 12 to win 10 means and everyone knows that 10 is 16.7% less than 12. So what's your point?

Q7: D, agreed

Q8: D, agreed

Q9: can't comment but are you saying that Las Vegas Sports Consultants have been making a mistake like this for years? Sounds hard to believe since those guys are pretty sharp. BTW it's "affects", not "effects"

Q10: A, or at least an approximation thereof. This guy obviously has no clue about the Kelly criterion and what a truly powerful method it is. Does he really think that all bets have the same advantage!? Is he that much of a moron!? Of course you have to bet more when you get a really juicy number and bet less when all shops have the same line up. And the part about blackjack is wrong, too. The bet size depends on 2 things -- the count and the current bankroll -- so it VARIES you big dolt!

If someone is an idiot, that in itself doesn't bother me, but if he pretends he's an expert and mixes in a few true bits of good advice just to make it harder for a beginner to tell, that's when I have to step in to straighten things out!

Go crawl back under that rock you came from and leave us at Rx alone! (not you, nicky, the guy who created this stupid test!)

Good to see you around Darryl Parsons
