Another difficult 1st hand to start with! All results different!

North has a difficult first choice 14HCPs but 9 tricks in ♠ s. Benji bidders will be able to open an easy 2♣ s (2♦ s for GF hands).

Standard ACOL can lie and open 2♣ (one trick off a game which is OK for many and probably best here) or risk a pass out of a 1♠ opening.

With Benji or Acol 2♣  opening it will go 

South will bid 3♣  to show 8+HCPs and ♣ cs

North will bid 3♠ s

South will have a choice 3N - length in ♥ s but no stops or 4♣ s to show strong suit.

Either way North has a difficult bid 4NT RKCB is not good with a void, though it works here.

Over a 4♣ response 4NT and a response of 5♦ showing 0 or 3KCs for ♣ s North will see all KCs and 2 sources of tricks so will bid 6 or 7♠ s or 6 or  7NT (that makes). (South will not mention the ♠ void as being in partners suit it is not a useful void). Duplicate players will bid the slightly riskier NT contracts (6♠  would be below average).

If North rebid 4♠ s south may also try 4NT RKCB for Ss North will also bid ♦ to show 3 or 0 and probably a source of tricks in ♠ s so south may bid 6 or 7NTs. Cautious ones may pass the 4♠ bid, but you have probably 3 qucik tricks on top of partners strong 2 opening so 6 should be safe.
