Question 1 (of 3 on this page)
Look at North's hand. Can you open the bidding ?
Answer
3 . no (or maybe yes, just depending)

Adding the length of your two longest suits comes to10 cards. Adding your points adds another 9. 19 altogether, not quite enough for the rule of 20. However: if you are in the third or fourth seat, and everyone else has passed, you can open, using the rule of 18.

Note: More advance players would in fact generally open with this hand in the first seat, because of the nice long 6-card heart suit with a couple of honours. Read about this in weak twos.

Question 2 (of 3 on this page)
Look at West's hand. Can you open the bidding ?
Answer
3 . no

Although you have 10 cards and 10 points, so that's 20 altogether, too many of the points are in the short suits, and are wasted
