    Moscow Escape - Especially when playing Weak Notrump openers, a 
    conventional countermeasure when opponent Doubles for penalty.  Here is 
    one of several escape variations used by players, this one an adaptation of 
    the DONT convention: 
      
        | Bid | Meaning |  
        | 1N - (X) - XX | Responder's Redouble shows 
        a single-suited hand |  
        | 1N - (X) - 2C | Shows a two-suited hand: 
        Clubs and a higher suit |  
        | 1N - (X) - 2D | Shows a two-suited hand: 
        Diamonds and a higher suit |  
        | 1N - (X) - 2H | Shows a two-suited hand: 
        Hearts and Spades |  
        | 1N - (X) - 2S | To play in Spades, taking 
        up more bidding space than beginning with a Redouble followed by 2S |  A popular adaptation to Escapes 
    includes:
 
      
        | Bid | Meaning |  
        | 1N - (X) - P - (P);XX
 | Responder 's Pass 
        forces opener to Redouble; the Redouble may show a 
        one-suited hand to be disclosed by responder or Pass to convert 
        to punish the opponents' for an ill-advised Double. Incidentally, 
        opener's Redouble functions similar to the Lebensohl 2 Notrump 
        conventional call, as: (2x) - X - (P) - 2N.  Thus, a 2 level 
        responder bid is to play and a 3 level bid invites game (stronger than a 
        direct 3 level bid over opponent's Double) |  
        | 1N - (X) - P - (P);XX - (P) - 2D
 | Responder belatedly shows a 
        single-suited Diamond hand; with a 4-3-3-3 hand, if opponents' again 
        Double, a subsequent Redouble is "SOS", asking partner to 
        name a longer suit |  
        | 1N - (X) - P - (P);XX - (P) - P
 | Responder shows good values 
        by subsequently Passing, anticipating making the 1 Notrump 
        contract for a good result; if opponents' enters the auction, their 
        contract will now likely be Doubled for penalty. |  Note: many creative escape 
    variations are in use today, requiring partnership discussion on specific 
    methods.    See SOS
