Magister
After opening 1 in color, one over one and the opening rebid at the level of one we follow the magister convention (also known as PRO) – the rebid of 2 ♣ is artificial, and promises a hand at least inviting with a five-card suit , or a hand with slam aspirations, or sign off on clubs.
Here are the sequences, in which the 2 ♣ question is the master's convention:
1♣ – 1♥
1♠ – 2♣
1♣ – 1♥/♠
1BA – 2♣
1♦ – 1♥/♠
1BA – 2♣
1♥ – 1♠

The opener with a minimum of openings with a doublet in the color of the first partner bids artificial 2♦, with a minimum of three in the partner's color – 2 in the color of the partner, with the top of the opening with a three in the color of the partner – 2 in the second color older, with a top without a font in the color of the partner – 2BA.
A repetition of clubs by the respondent indicates that he has a weak club-suit card and is the sign off. With an invitational card with the senior five, after 2♦ answering bids 2 in your color, and after the partner indicates the maximum – chooses a contract. 2The BA bid by the respondent indicates slam aspirations and is a question about the younger four.

Such 2NT only pushes up to the height 3 in the color of the opening – after the indication of the shortness, back on 3 the opening color is sign off.

The question of kings – Hoyt – after being asked for aces, the lowest bid without the agreed color is a question for kings. He responds normally (And rung – 0 the 3)
Trump convention – 5A BA bid for Blackwood or a skip is a question about senior trump honors; are following: 6♣ – 0 figure, 6♦ – 1 figure, 6♥– 2 figure, 7 in the agreed color – 3 figure.
Exclusive Blackwood: after agreeing on the color, bidding on a new color with a jump in height 5 (or 4 ♠ with agreed hearts) is Blackwood exclusive – asking for aces beyond the off color and the trump king (4 values). We respond by rungs, like after Blackwood – And rung – 1 the 4 values, 2nd level – 0 the 3 values, 3rd level – 2 worthless values, td.
DEFENSE BIDDING
Color entry at the height of one – can only be an indication of the visa; after such entry – 2♣ it's Drury with fit after entering 1 in the senior, the new color at the height of one and three is forcing, at the height of two without a jump, it does not force (but it's constructive); the new double-hop color is a fit color, Splinter only in the color of the opponent; color for jump input – blocking.
Color entry without a jump at the height of two – should be decent, basically from more or less 12 PC, after such an entry, the new color does not force two (but it's constructive), forcing at three.
Color jump input – is blocking (after enter 2♥/♠ we use the question about the single)
Callback – we play the call counter after openings up to high 4♥ inclusive. The counter to higher openings has a considerable degree of discipline.
After the calling counter for opening 1 ♣, we use an artificial negative 1♦, after a counter to a different opening, we bid naturally.
After the calling counter for the weak opening 2 in the older one we use Lebensohl.
After the callback, bidding II of the defender in the color of the opponent provides, that he will take the floor at least once more in the auction.
After the counter and free bidding of the defender II, promising strength from 7 PC and sold by counter explanatory counter, bidding is forced to win.
After the starting counter and the bidding of the second opponent in a new color, the counter is punishable.
After the calling counter and picking up the older opening color, a double is a hand without a four in the senior suit.
Callback on 2♦ multi or Werewolf means a hand with a heart fit – it is given to the opening variant with the peak color.
Cue Bid Michaelsa – entering with an opponent's color means at least two-color 5-5 with the oldest of the colors not auctioned off (with the two lowest we enter 2NT). Here is a detailed description:
1♦ – 2♦ = two-color with spades
1♦ – 2BA = trefle i kiery
1♥ – 2♥ = two-color with spades
1♥ – 2BA = trefle i kara
1♠ – 2♠ = two-color with hearts
1♠ – 2BA = younger colors
As a supplement to this scheme, you can accept two-color cards after opening the opponent 1 ♣ as opening or using 2♦ Wilkosz (depending on the regulations of the regulations permitting systems at a given event).
Cue Bid Michaels is unlimited – in favorable assumptions it may be very weak, and there is no upper limit. The second bidding of the opponent entering the opponent's color with a two-color means forcing to the.
Input 1NT – is natural, means strength 16-18 PC with a stoppage in the color of the opponent. We continue to bid as if we opened 1NT. After a counter to enter 1NT, the redouble is SOS, and abolition – natural, weak. We treat the 2N entry in a similar way after the opponent's opening is two.
A 1N re-open entry indicates strength 11-15 PC and does not promise to stop in the color of the opponent.
2NT input – means two-color on younger colors. In the re-open position, it means strength 19-21 PC with a stoppage in the color of the opponent.
After opening, 1NT is strong
against – „bi” – the older four and the younger color 5+, may be on the resume 4-4
2♣ – older colors (now 2♦ is a deal question)
2♦ – one color older
2♥/♠ – the color of the auction and the younger color 4+,
After opening, 1N was weak
Against – strength, inputs – j.w., but constructive force.

After color entry – Negative counter up to height 3 inclusive, On the height 4 versus "point", the new color does not force at the height of two, forcing at the height of one and three (in the two-sided auction, we use the older colors preference); reconciliation of the opening color with the jump – blocking; jump into a new color – natural, forcing to match; double jump into a new color – color + fit; the color of the opponent with a jump – Splinter; the color of the opponent – exactly invit with fit in the color of the opening; 2BA – forcing to a match with fit in the color of the opening
