Need som help to understand a bid

I had the following hand
S - x x
H - E
D - E Q 9 x x
C - 10 8 x x x

My partner had
S - E K x
H - x x x
D - K 10 8 x x
C - E K

I opened with 1 d
my partners response was 2c
the bidding sequence was then as follows
me: 3c
partner: 4nt
me: 5h
partner 6c

I need help to understand his response of 2c after my 1 diamond and why he said 6 c after 5h.

What sort of game was this ?

I know some people play 2♣ over 1♦ as an artificial GF, but I suspect what's going on here is:

You're not playing inverted minors so there is no forcing raise.
Partner needs to invent a forcing bid and it's less dangerous to do this in a minor suit than a major.

6♣ is just insane, I suspect he meant to bid 6♦, or forgot he hadn't agreed diamonds yet and was making some sort of grand slam try.

Minor quibble.....Many of the posters here are multilingual, but most of the English-as-native-language people are embarrassingly unilingual (as I am), so please try to use A for Ace rather than E...I don't mean to be rude or to discourage you from posting! It's our problem, rather than yours, but catering to our deficiencies would be kind . On this hand, it was easy to figure out that E was Ace, but some hands in the future might not have Kings in them

As for the problem, I suspect that the initial 2♣ response was his way of ensuring that you didn't pass....that either your methods contain no forcing raise in diamonds or you had no agreement, and he didn't want to risk a pass by you if he raised diamonds. He did well to avoid bidding a 3 card major or notrump.

4N was horrible, but, again, I suspect that he wasn't sure what was forcing after 3♣. Bidding blackwood with xxx in a suit neither of you has shown a control in is very bad. But, he had slam interest, the odds were that you held a heart control or that they wouldn't lead the suit, and he had no idea what else to do.

So I understand everything to that point.....I wouldn't do any of it, but I wouldn't be in his situation anyway, because even in casual partnerships, minor suit raises are one of the 5 or 6 things I always discuss, even if briefly. But I don't understand 6♣...there is no plausible explanation for not bidding either 5N (since he now knows you hold all the Aces and you are almost unlimited) or, if he is giving up on grand, 6♦. I think maybe the strain of having to fudge his way through the earlier rounds got to him and he just made a silly mistake, as most of us do from time to time.

The main difference between an expert and a B/I is that the expert's mistakes are usually more subtle than those by a B/I player but, in context, they can be just as silly.

Thank you for helping me.

We made the contract anyway. But it would had been easier to make 6 d or even 7 d.

I have been searching the internet and have found something called kokish rebid. Could one say that his bid of 2c was to start a rebid.

He is the one that is in control. He knows that I have at least 3 diamonds and that it is my best suit of minors. He also knows that I have no 4 suit of
majors.

Could it be that the 4 nt was not blackwood or rkc blackwood making my 6h faulty?

As I understand it Kokish is after a 2♣ opener not response (basically allowing you to bid 2♣-2♦-2N in two different ways to keep the bidding low. Whether somebody has expanded its role by applying it after an artificial GF 2♣ response I'm not sure.

Does he really know you have no 4 card major ? how do you bid a 4054 12 count ?

Unless you're a well established partnership and have agreed something different (like an alternative ace asking method like kickback or minorwood) then 4N is Blackwood in clubs here.

Looks like your partner was drinking some great stuff.

When opening with 1d he should know that I had at least 3diamonds. When I raise his 2c I promise at least 4 cards (clubs) as well as 5 diamonds. Since there is a priority
to bid a major if four cards. He must know that i lacked a suit of for of a major.

In many normal systems, 1♦-2♣-2♠ shows a lot more values than 1♦-2♣-3♣.
