- ~SAside: Not possible to accurately calculate % probabilities of card/suit distributions amongst the hands. The bidding is an indicator of this abnormal skewing.
**From:**jjewels212 <julisinchicago2@...>**To:**EuchreScience@yahoogroups.com**Sent:**Sunday, May 29, 2011 5:53 PM**Subject:**[EuchreScience] Leading to your partner at 9-9I was playing in Pogo with one of my most favorite partners, one of the best euchre players I know. It was his deal at 9-9. Unfortunately, I don't recall all the cards.

He picked up the jack of hearts. I held 2 clubs, K 9 diamonds, and Jd. I trumped the spade lead. Partner threw off a diamond. Out of habit, I led a club because I never lead the suit my partner throws off. I typically assume he discarded from a doubleton. If I lead the other suit, I will generally hit his void.

My partner got set, but a diamond lead would have made the point. My p said, at 9-9, I should have led the diamond after he threw off. He said it's best to assume he picked up very thin and that he would discard his singleton on the first trick. If he discards from a doubleton, he reasoned, my lead wouldn't make any difference because he would have 3 trumps and should be able to make a point no matter what I led.

Does his reasoning make sense to you? YES As a general rule, do you think it is best to lead the suit your partner throws off when the score is 9-9? YES

> not? I am saying the probabilities cannot be precisely/correctly calculated using combination and permutations which is Robster's method. Note the modifiers 'precisely/correctly'.I am saying you cannot precisely calculate the probability (odds) of a player havingÂ a card using combinations and permutations after a bid has been made because that method does not account for the information contained in the bid.Â Example:Â Â**If I order up the 10S from the 1st seat and go alone the odds of me having the A of spades is higher after I bid than before I bid from the view point of any other observer**.

But,**such an order was not made by either of the 3 seats who had the option therefore this particular argument cannot possibly be relevant to the situation in question.**My example above was to illustrate a point and did not directly pertain to the original question. MY POINT: ALMOST ANY BID SKEWS THE ODDS OF THE BIDDER'S HAND HAVING CERTAIN CARDS.Probably true, but you cannot use combination sand permutations to figure it out the odds mathematically. IMO you could mathematically make 1,000s of observations of a particular scenario, create an average, determine a standard deviation and come up with the 'odds' and the 'margin of error' ... but the is NOT WHAT the ROBSTER does and it is an impractical solution.

And surely, with a good mathematician and enough effort a precise acceptable margin of error, to allow for bid bias and dealer pick up or turn down could be worked out. Also, IMO a bid bias margin of error for the situation being challenged would be almost insignificant to the whole picture.This is ridiculous, but I guess you could make 2 observations for example and says the odds are 50% give or take 49% .. an accurate statement but what good is it?> Your response does not make sense to me. How can one make good logical decisions using incorrectly calculated odds?Â You can't.Â Â Robby bases his odds on mathematics that ignore the biasÂ of bidding.Â

spades.Â 2nd seat knows the chances of 1st seat having the A of Spades is (24 - 6) = 18 unknown cards and 1st seat has 5 cards .... 5 chances in 18 or 27.8%.Â [Wow â€"Â Bozzo the Clown doing Math. The chances of 1st seat having the Ace of Spades with five cards dealtÂ is 27.8%. Wrong calculation Fred - not how you do probability or combinatorics.]
