Calgary 2/1 with ‘Right-siding’ Transfer Bids

Jim Berglund

Note: Unusual treatments have a Blue background or are highlighted with bolding and italics

Bidding Sequences are assumed to be Without Interference. (A general guideline is that Bidding becomes ‘natural’, or ‘systems off’ after interference)

The purpose of this system is three-fold: ©to improve the odds in right-siding the contract

(having the weaker hand exposed)©to add more granularity to bidding – wherever

possible, giving a precise, unique purpose to each and every bid

©to define strong suits and identify slam prospects quickly and at lower levels.

The 1 Opener and 1♣ ResponseOpener Responder Rebidder Advancer1♣ - Any unbalanced hand with 5+ clubs, or any balanced hand with fewer than 15 points or 17+-19 points. Must be Announced. “Could be short”, as opener could hold as few as 2 clubs.* More than 30% of all openings will classify. This means that you should spend some time mastering these sequences until they become ‘natural’ to you

1♦ - Must be Alerted – “Waiting, shows no 5-card major” (Montreal Relay).’*Typically’ shows 4+ ♦, or 6-10 points balanced, since balanced hands with more than 10 points are shown with a NT bid, and there are other game force bids that can be made with other unbalanced hands. OTOH with ♠AKxx ♥AKxx ♦AKxx x, a 1♦ bid seems right…

1 ♥ - Shows a 4 card suit1♠ over 1♥ may be bid with 3♠ and a minimum hand allowing opener to bid 1NT with minimal values and a flat hand; this is non-forcing and must be Announced, “Could be as few as 3 spades” ; anything other than 1NT or 2♣ by opener shows extras 1♣-1♦-1♥-2♠ or 3♦ are splinters in support of hearts (see XYZ) 1NT shows 8-10 HCP (with less, over 1♥ you’d bid 1♠, if possible). Note that we avoid playing 1NT from the wrong hand, wherever we can.A raise to 2♥ may be made with 3 cards to an honor and 6-8+HCP (see XYZ)

2♣ is a transfer to 2♦. The next bid is invitational (XYZ)2♦ is an artificial game force (XYZ)

1♠ - Shows a 4 (or 5*) card suit and denies 4 hearts. * with weak 5-5’s only1NT typically shows 8-10 HCP 2♣ is a transfer to 2♦. The next bid is invitational (XYZ)2♦ is an artificial game force (XYZ)

1NT - Denies a 4-card major, non-forcing. May have 5♣/4♦2♣ - Shows 5 or (usually) more clubs with minimal values 2♦ - By agreement - shows 5+♣/4+♦ - this is a reverse, not a raise (since the 1♦ response may be artificial. It should always show a very good club suit 2♥/♠ - A reverse showing very good clubs and a second suit2NT - 18-19 HCP, balanced, may have a 4 card major (use Check-Back Stayman)

Almost one-third of all openings will be 1 . ♣Hence, there is a lot of opportunity to precisely define responses and follow-on sequences. The four key differences are:© frequency and flexibility of the 1♦ response© the certitude of 5-card major responses© higher point-count of the NT responses © the 2-level, 2-way transfers.

If your partner opens one club, you must state this, out loud, to the opponents. If asked “how short?”, say ‘as few as 2”If asked “How big?”, say “11+ (HCP)” and add “non-forcing”Rule: In Bridge, you NEVER hide any special understandings from the opponents

Montreal Relay is a complete bidding system developed by Eric Kokish, a Canadian expert. This system uses only the 1 -1♣ ♦ sequences.

The XYZ convention is invoked over any three bids at the one-level (without competition). Basically 2 ♣ is a relay to 2 ♦ with invitational values (TBA), while 2 ♦ is an artificial game force.

An artificial bid has a meaning other than what you would expect. It may be part of a convention or just a treatment

Major Suit Responses to 1 Openers♣

Opener Responder Rebidder Advancer1♣ 1♥ 1♠ - shows fewer than 3 hearts and 4 spades

1NT shows a minimum, (12-14 HCP) balanced hand

2♠ - shows a minimum hand and 4 Spades

Any other bid is as shown below

1♥/♠ - Shows at least 5 cards in the suit and a good 5-15 points

1NT – minimal, balanced hand, less than 3 in the bid major

2♣ is a transfer to 2♦. The next bid is invitational (XYZ)

2♦ is a game force (XYZ)

2♣ - Shows 5 or more clubs with minimal values and no raise for partner

Raise - minimum raise with 3+ cards

Jump raise – invitational raise with 4 trumps, or 3 to an honor and/or extras

2♦ - By agreement - shows 5+♣/4+♦ - this is a reverse

2♥/♠ (not a raise) a reverse - usually shows an excellent club suit

2NT - 18-19 HCP, balanced, may have (the other) 4 card major (use Check Back Stayman)3♣ - concentration of values - invites 3NT or pass

3♦/♥/♠ - singleton or void in support of the bid major, with extras

3NT - To play; a 4♣ bid by responder is Revised Gerber; 4 of the major is 1430 RKC (for the major); 4NT is quantitative, asking partner to bid 6NT with ‘extras’, (but seldom used in this sequence;) any other suit bid is exclusion Blackwood

Exclusion Blackwood is triggered by jumping to a suit bid (showing a void) above the expected suit game. It asks

partner to bid the number of Aces and Kings (second bid) not counting any in the

bid suit

INVERTED MINOR

Opener Responder1♣ 2♦ - 0-5 - HCP - weak transfer to hearts or slam interest; any advance by

responder is 1430 key card and shows a great suit; Over 1430, the next bid asks for second-level controls( incl the trump Queen). Bidding NT or raising the known suit to game shows no interest. Other bids show suits; a jump to a suit shows slam interest and a void.

1♣ 2♠ - 0-5 HCP - weak transfer to diamonds or slam interest; any advance by responder is 0314 key card and shows a great suit. Over 0314, the next bid asks for second-level controls( incl the trump Queen). Bidding NT or raising the known suit to game shows no interest. Other bids show suits; a jump to a suit shows slam interest and a void.

2-Level Transfers over 1 Openers♣

Remember - we use 1430 over majors and 0314 over minors – always!

Note: These bids are used where 1-level responses don’t ‘fit’.

They describe weak, preemptive Suits or very strong, slam-ish suits.

This technique typically right-sides the contract.

When strong, it shows a hand that can be played opposite a singleton

or even a void. Your partner doesn’t need a fit for slam – just

cover all 6-10 point ‘flat hands’ as well as many hands with 4 or

more diamonds.
