HOW DO YOU INTERPRIT YOUR PARNER BID

i think its best to play 2C as natural here.

[Double !]

I would interpret the 2 club bid as being natural, showing decent clubs, and not some sort of cue bid. RHO opened 1C which could be on a 3-card suit (for some, even a 2-card suit). If I wish to make some sort of cue bid to show extra values or ask partner to bid his/her better major, I usually cue the suit that was bid to my left (assuming that the bid was not artificial). The reason is that I am much less likely to want to play in a suit bid to my left, sitting behind me, than in a suit to my right where I am sitting behind the person who initially bid the suit (finesses are more likely to be successful in the suit).

I can't state for sure that there is universal agreement on this, but it seems logical.

Consider the following bidding sequence (somewhat related to the topic): LHO bids 1 club, partner passes, rho bids 1 heart, and you bid 2 hearts. This is natural, showing a good heart suit and a reason to bid. Again, you are sittting behind the person who initially bid the suit.

Hope that this is helpful. Can't wait for everyone to disagree with me. lolololol.

This should be natural. Notice that doubler promises 4-4 in the majors so there isn't a real need to look for opener's "better major" unlike in the auction 1♣-X-P... where opener could be 4-3 or even 3-3 majors and there's some need to show two places to play.

Elianna and I (with some help from Josh Sher) have a fairly complete set of rules for when cuebids can and can't be natural. Basically:

(1) If partner has bid a suit naturally, then a call in a suit that opponents have bid naturally cannot be natural. So 1♣-1♠-P-2♣ is artificial. Usually this is a strong raise (or occasionally just a big hand if new suits would be NF).
(2) If only one suit has been bid naturally by the opponents then a bid in this suit cannot be natural. So 1♣-P-1NT-2♣ is artificial, but 1♣-P-1♥-2♣ is natural. Usually this shows a two-suited takeout (if at the two-level) or acts as a stopper ask (three-level).
(3) If the opponents have bid and raised a suit, then bidding that suit cannot be natural. So 1♣-P-1♠-P-2♠-3♠ is artificial, but 1♣-P-1♠-P-2♠-3♣ is natural.
(4) In most other situations "ambiguous" cuebids are natural.

While our agreements are more specific than anything in the sayc document, I believe they are fairly standard.
