Moscow Escapes

Moscow Escapes are a "runout" convention after your side has opened 1NT and the opponents double for penalty. Aside from a redouble, the direct responses are identical to the DONT convention.

Partner		Opp 1		You		Opp 2
1NT		X		?

Partner		Opp 1		You		Opp 2
1NT		Pass		Pass		X
?

After the opposing double, the conventional bids are as follows.


Pass:
To play.

XX:

Requires partner to bid an artificial 2. Shows a one-suited hand. With clubs, simply pass partner's 2 bid; otherwise, correct to 2//.


2: 

Shows clubs and a higher suit (at least 4-4). Partner can pass with club tolerance or bid 2 to fish for the higher suit.

2:

Shows diamonds and a higher suit (at least 4-4).

2:

Shows hearts and spades (at least 4-4).

2:

5+ spades. Depending on partnership agreement, this may be weaker than a redouble followed by a 2 rebid. Alternatively, it may promise more strength than the redouble sequence. Either way, it's still non-forcing.

Note that with a balanced 4432 and reasonable strength, responder may pass rather then bid at the 2-level.
