6♠？这是粗枝大叶的感觉牌，缺乏必要的技术含量，真的没意思！

那么，您是如何细致而合理地叫上大满贯的？

4NT一5C

5D 一7C

5C(1A)，5D(问SQ)，7C(有SQ十CK十CQ)。

Try with the recently practice relay system CHAOS:

 

1♦ = (10)11+, 5+♥ except 4♥ UNBAL, including 5♥5+♠

......1♥ = 8+, relay

1♠ = (10)11-14, MIN

......1NT = FG, relay

2♦ = 5 or 7 card ♥ w/ 1♦ OR 4♥ UNBAL

......2♥ = relay

3♦ = 4513 (start to probe 6♠)

......3♠ = RKCB in ♠

3NT = 1 or 4 KC (good news)

......4♦ = Traditional Spiral Scan

4♠ = w/ ♠Q, w/o ♥K (6♠ very likely)

......4NT = Parity Spiral Scan for ♣K, ♦K, ♥Q

5♦ = ♣ K or ♦K + ♥Q (i.e. ♣ K)

......5NT = Traditional Spiral Scan (confirm ♣ Q not missing, not ♦Q instead)

6♦ = w/ ♣Q, w/o ♦Q

......7♠ = S/O
