East will open 1♥ with the aim of bidding ♠ s ac ouple of times to show 6+♥ s and 5+♠ s. 

According to the EBU bridge book it is not strong enough to bid a strong 2♣ 

5 D Rules for “Strong” opening bid 5 D 1 To be considered a “Strong” opening bid, the minimum allowed by agreement is:

• (a) Opening bid of 1♣  or 1♦ : at least 13 HCP
• (b) Above 1♦ : at least 16 HCP, or 13 HCP concentrated in two suits containing 10+ cards.

Though it is close on point (b)

South will pass

West will bid 2♣ 

North will pass

East with a reverse will bid 2♠ showing 5+♥ s and 4+♠ s

West will bid 3♦ s 4th suit forcing 3NT would risk being passed whilist there is a possible slam). (That allows East to show the shape of  6+♥ s and 5+♠ s.(with 5/5 or 6/6 East will have opened 1♠.)

East could now show 3♠ s by bidding 4♠ s but there is a risk this would be passed.

The better altrnative would be for West to bid RKCB 1430.

This makes it difficult for East to respond as he has a void in ♦ s. 

The normal response would be 5♥ s to show 2 Key cards without the Q of trumps.

With a useful void (more useful when there is opposition bidding). so in addition to the standard responses of:

• 5♣ =1 or 4 KCs
• 5♦ = 3 or 0
• 5♥  = 2 without Q trumps
• 5♠ = 2 with Q trumps

The great Larry Cohen is a bit anti bdding RKCB with voids amd here is an interesting article why, but also includes links to RKCB additional systems. His and many other experts like cue bidding to show the controls.

In addition you can show a useful void (simple system) by bidding:

• 5NT = an even number of KCs and a useful void (Here 2 as East cannot have 4 as East has 2! and unlikely to have 0KCs).
• 6♣  = an oddd number of KCS and a useful void (♦ s as not partners suit of ♣ s as holding a void in partners suit is not a useful void)

So Larry would generally accept that 6♠ will give a good score.
