whats the range for 1nt overcall

[jocdelevat]

Hi all

 

I play 1nt 15 -17 hcp for openning bid and second seat overcall however I do not know

1.how many hcp you need to overcall 1nt in these 3 auctions.:

 

A. pass pass 1x 1NT

B. 1x pass pass 1NT

C. 1x pass 1y 1NT

 

2.Does the 1nt overcall should be explain if the range in these auctions is not the same with what I have in my cc?

 

Thank you in advance for your advice.

A. Standard is 15-17, sometimes a bad 18.

 

B. Standard is around 11-14. Some play a bit lower (10-12), others play it dependant on what 1x was (for x=♠, for instance, it can be 12-16).

 

C. Standard is around 15-18. Some play it as a weak 2 suiter on the unbid suits.

A. A good 15 - 18 (some would say 16 - 18)

 

B. Depends on whether x is a major or a minor

 

over 1m, 1NT shows ~ 10+ - 13

over 1M, show ~ 11 - 16

 

C. If you play 1NT as natural, which many do (I do)

 

1N shows a very good 15 to 18

A. If opps suit is a major (especially spades) the upper limit is somewhat higher because the alternative is to double followed by 2NT, which is not very attractive. If opps suit is a minor, the alternative is to double followed by 1NT. Therefore. when I double 1♠ I might have a decent 19 points, while when I double 1m I have at most a modest 18.

 

Points counts are less important for a 1NT overcall than for a 1NT opening. Suppose RHO open either 1♥ or 1♠ and you have:

KJx

Axxx

KJx

KJx

 

This is a fine 1NT overcall against 1♠ because you have probably two spade tricks and chance of setting up a length trick in hearts. Against a 1♥ opening, you have only one heart trick and no length in other suits - the heart length is worthless unless your x's are better than RHO's.
