Brozel Escapes

Brozel Escapes are a "runout" convention after your side has opened 1NT and the opponents double for penalty. The direct responses are very similar to the Brozel convention for overcalling an opposing 1NT.

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:

Pass Requires partner to make an artificial redouble. Shows either a good hand that wants to play 1NT redoubled, OR a one-suited hand (5+ cards). After partner's redouble, all bids at the 2-level are natural and non-forcing.

XX Shows one of the following two-suiters:

Clubs and diamonds (at least 4-4).
Clubs and spades (at least 4-4). Note that in the Brozel defense to 1NT, this hand is showed by a direct 2. However, in the Brozel escape system, a 2 reply is natural.
Diamonds and spades (at least 4-4).

After hearing the redouble, partner must choose which action to take:

2 - Shows club tolerance, If partner has diamonds & spades, he will correct to 2.
2 - With a club doubleton or with 4-4 diamonds and spades, bid 2 and ask partner to either pass, or correct to 2 if he holds clubs & spades.

2 Shows clubs and hearts (at least 4-4). Partner can pass with club tolerance, or correct to 2 with longer hearts.

2 Shows diamonds and hearts (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.
