          The Baron Two Spades Convention | 
            | 
        
        
          |   | 
          When partner opens 1NT most people these days play transfers, so the 2♠ bid is ‘spare'. I explained many of the various options for the bid in “The 2♠ response to 1NT”. This document outlines the Baron 2♠ convention which is fairly popular in the UK and is part of the Standard English Bidding System.   | 
            |

              |   | 
              2♠ =  | 
              either | 
               a balanced raise to 2NT with no 4-card major.  | 
             
            
              |   | 
                | 
              or | 
               a game forcing hand with slam interest and usually no 5-card major.  | 
             
            
              |   | 
                | 
                | 
                | 
             
            | 
            | 
        
        
          |   | 
          There are two treatments as to what opener does with a maximum:  | 
            | 
        
        
          |   | 
          a) Opener bids 2NT with a minimum and with a maximum bids a 4-card suit (up the line).   | 
            | 
        
        
          |   | 
          b) There is alternative set of responses when opener has a maximum:  | 
            | 
        
        
          |   | 
          
            
              |   | 
                | 
                | 
             
            
              | 3♣ | 
              = | 
               no 5-card suit  | 
             
            
              | 3♦ | 
              = | 
               5-card ♦'s | 
             
            
              | 3♥ | 
              = | 
              5-card ♥'s | 
             
            
              | 3♠ | 
              = | 
              5-card ♠'s | 
             
            
              | 3NT | 
              = | 
              5-card ♣'s | 
             
            
              |   | 
                | 
                | 
             
            | 
            | 
        
        
          |   | 
          With an invitational hand responder will pass 2NT with a minimum or bid 3NT over a suit bid by opener.   | 
            | 
        
        
          |   | 
            | 
            | 
        
        
          |   | 
          With a slam seeking hand a 4-4 or better suit fit will always be uncovered if there is one when using treatment (a). | 
            | 
        
        
          |   | 
          Treatment (b) is an improvement that enables both 4-4 and 5-3 fits to be located. With no 5-card suit opener bids 3♣ and then responder will bid 4-card suits up the line. | 
            | 
        
        
          |   | 
            | 
            | 
        
        
          |   | 
          When playing Baron 2♠, the direct 2NT response is used when responder has a weak hand with a long minor and wants to play in 3♣ or 3♦ .   |
