The Rule of 80%


-
Play

If you’re 80 percent sure of what the final contract will be then just go ahead and bid it. Good enough! Every bit of description you give to your partner, you give to your opponents as well. Extra bidding will just let the opposition know how to defend and, in particular, what to lead.

    If you don’t bid the Cs (like I did the 1st time), you get a Club lead and contract makes 1. If you do, you get a D lead and contract goes down -1.

    I had the same result as dlash — except if you go after the spades rather than the hearts, you can make 3 nt.

    Awesome video @graeme. I like the rule of 80% almost as much as the 4NT asking for courage.

    Fabulous video as always Graeme, was going to bid 3 but whimped out and ended up in 2NT making 10, will have another go and see if i can make 11. What you say makes so much sense.

    wadkin37 @ Graeme You’re so imaginative! (and so right, too) I bid the club suit and gave away the hand. What I had in mind was the
    suggestion that the stronger hand should bid the NT so that the lead comes into that hand…so I gave Partner the
    opportunity to bid the NT. Your instant 80% rule makes much better sense. Thank you!

    The first time I played it in 2NT, my partner left me hanging, and made three. However, after reading that others had played it in 3NT and made five, I tried it and could not make more than our bid…

    I kept away from bidding 3C but bid 2NT expecting partner with 13 points to put to 3NT – didn’t happen sadly, made 11 tricks. Club was led which I won in hand played JS to clear the A, won the next club played towards 10H to clear that ace, leaving 2 aces in dummy to get access. Lovely to play just in wrong contract!

  26. Graeme I agree with the 80% rule and its sibling “If you know the right thing thing to do, do it , don’t let partner make a mistake when you can prevent him from making it.”
    PS Have you being taking lessons from fisher and schwartz on claiming tricks as you made ten not eleven tricks.

    Made 11. The opposition led a club which I took with the king. Drew the spade A won the lead back. Drew the heart A and then won the rest. The only tricky part was making sure I could get back to the top hand to play out the spades.

    @Graeme, played this hand about four times and found it a very good learning hand. I finally figured to get both spade and heart aces in early, so the diamonds didn’t get me later and I made 11. I find NT tough to deal with for some reason. Thanks for all the help you guys give us.
