Two-suiter overcalls

The two-suiter overcalls after an opening of 1 of a suit are the famous Michaels.
A two-suiter overcall guarantees:
  • two strong suits of at least 5 cards,
  • about 10HCP, (sometimes less......with no top limit),
  • the high cards in these 2 suits.
  • You should pay more attention to the quality of the suits and to the vulnerability than to the number of points !

Problem E5391 2 A Michael doesn't always need 10HCP. Here it's the absolute minimum!
 
 
The various two-suiter overcalls:
  • 2NT shows 5-5 in the two lowest ranked suits (after all one level openings)
  • 2 diamonds after a one level minor opening shows the 2 major suits 5-5
  • a cue bid after a one level major opening shows the other major and the clubs 5-5
  • 3 clubs after a one level major opening shows the other major and the diamonds 5-5

Problem E3790 2NT with jump = the 2 lowest ranked suits of the remaining 3. This means never spades, never the opponents' suit.

Problem E4401 2 It's up to the Partner to decide which major he likes best. How many HCP for a Michael? It varies according to the vulnerability. How to decide? The main criteria are the respective strengths of hearts and spades.
 
 
The cue bid of the opener's major shows:

   About 10HCP
   Two strong 5-card suits
  • the other major
  • and clubs.

   about 10HCP,
   2 strong five-card suits:

Problem E4147 3 Michaels Precision - CA-. are weak, but the 6 are fantastic. With a 2-suiter 6-5 feel free to invervene with a Michaels. You don't need to be as careful as with a 5-5.
