Rule of Seven and the Danger Hand

Some more examples of using the Rule of Seven and deciding which is the danger hand

The links to replay the hands are:
• Number of times to duck = SEVEN – (Total number of cards you have in that suit).

• Use the Rule of Seven to duck twice. You hope that the hand with ace of diamonds does not have 5 or more hearts: http://tinyurl.com/y7n7n4fx

• If the hand with the ace of diamonds has 5 hearts, the contract cannot be made https://tinyurl.com/yxuullye

• If the hearts divide 4:4, you would be OK too https://tinyurl.com/y4fxd2c7

• Duck twice, then play the diamonds in such a way as West, the dangerous opponent, cannot gain the lead: WEST=DANGER https://tinyurl.com/ydxncf7r Even if the finesse loses, you have prevented West gaining the lead https://tinyurl.com/y9gja8jg

• Played Correctly POLL which is the DANGER HAND the hand we do not want to gain the lead? https://tinyurl.com/y99xzmxc

• Played incorrectly https://tinyurl.com/yc8vjhsj

• Played Correctly if the finesse fails https://tinyurl.com/ycjq9frq The KH is protected. It does not matter who has AH!

• Finally, do not duck if you are even weaker in another suit https://tinyurl.com/y4rdhbsh That lead of H2, looks like it is 4th highest, so the hearts are dividing 4:3 and are not such a threat. Diamonds are a greater threat if you let East win the first heart he may well switch to a diamond. https://tinyurl.com/y4hv65k2
