The analysis is based on following points: 1)System 1C 17+, 1NT 15 17, 5
card major, precision 1D.2)Mainly for intermediate level of players.
Pass. 1D. Pass by South with 2 3 in majors (though 13 hcp). 2C pass 2NT pass 3NT. Without 2C bid, opening lead would have been Club jack, so south will lead Dia Jack (or 10 if decided so). Declarer can develop 4 Club tricks, thus 8 tricks. 3NT –1(1Sp 1H 2Dia 1Club)is more likely than
3NT making on say Heart king lead. East to for NS to tackle hearts, else –1.

Pass 1NT by South all pass. Assume spade 7 opening lead. try his best for some endplay
If
doubleton, 1NT is not difficult. South must plan for Club ace duck twice if Axx/Axxx. Club 10 to jack, use the entry to finesse Dia 10.Later Club
to dummy’s 8, wins, repeat Dia finesse. With two Club tricks in bag, South makes 1NT. South to void two rounds Of Club Q & 10 from hand. Bidding part, East may balance, both majors 2C Landy. He gets 4 4 Spade fit, but bad play may result in vul 2 down 200 to NS.

to discourage (not count).West may risk Heart Q king, south completing discourage message. North can see 9 tricks, tries Spades, encouraged by south, no OPTION BUT To PLAY Dia for many down. If west decides to run Clubs, declarer likely to score Dia king. Though west discards Spades, they are blocked, north unblock AK is practically ruled out (experts may, if Spade discards by west are seen & south some +ve attitude in Spades).3C bid min hand, so pass 3C with aceless 11 also possible few tables.

Bidding:1) Few players
keycards are missing. 3) Few players 6Sp,via 4NT, positive thinking on which two keycards are missing. Well done today, as 6Sp is making. 3) Setting trump suit & cue bidding players. Exclusion Rkcb in partner’s side suit, must be well discussed.
Whatever method, which two keycards are missing is known only after the deal is over. Play: Dia lead win in hand. Spade 4 0 break, West to rely on 5 Club tricks. 5 + 0 + 2 +5 =12.

On Heartlead, Club 9 & 8 are not full stoppers, but useful cards. On Club lead, East to insert 10, to maintain communication with west. Both leads, Dia finesse is ON, 3NT easy. Not this hand of bad hearts & less hcp, but say nonvul vs vul or better hand, East may bid two suitor: 1D 2NT (Heart Club) & 1D 3C (Spade Club). Sayc 1C, then Heart Dia ,Spade Dia respectively.

bids 5D, as 4D is nonforcing. 6 cards poor quality Dia & 4 cards 3 honors Clubs... North may think of 4H bid, pick minor. But at the end, will leave this thinking & bid 5D.How to bid 6D ? North does not know 4 prime cards of south & south doesn’t know Spade void. So 6D bid looks difficult. ------
