Even playing Benji Acol, where you have a game forcing 2D and a 2C showing 8+ playing tricks available, this hand is still only a 1S opening. You want bidding space to show your 2-suited shape. The 5C response is of course daft. A 4C jump will show a solid, self supporting suit and would be reasonable. A 3C response would also be possible.

But here I disagree. I think 5♣ should show something like ♣QJTxxxxx and out. The solid club hand can start with 4♣.

Are you sure that it is a good idea to bid 5♣ on QJTxxxxx and out? If opener has a long major an a void in clubs, 5♣ could take us beyond our only making game.

Not that it is a big deal - giving a definition to the 5♣ bid shouldn't be among the first things to discuss in a new partnership

Absolutely. I am not sure it is a good idea to bid 5♣ on any hand at all but the 2 loser suit is one that has enough parallels in bidding theory to seem a reasonable definition if we really feel the need. Any better suit and we either want to keep 3NT in the picture or maintain bidding space for slam. I suppose using it as XRKCB agreeing some other suit would be another possibility if we really wanted to find something vaguely useful but that is just asking for trouble.

Anyone have talked about 5♣ bidding but, if let us consider the hand of my partner and evalute it in accordin to the F. Dudley Courtenay "Losing Trick Count" we can say that : with 14 losers is possible for partnership to play a game in a major suit, with 12-13 to play a game in a minor suit, with 11 losers a little slam. With my 2♣ i'll sure almost four losers (strong hand) or three (very strong hand).

Assuming you actually play it in one of your suits. Here you played in clubs where you really have a 7 loser hand (though could be reduced to 6-6.5 for those majors).

Clearly it confirms, with another point of view, what i've told explaining partner bidding: the message should be "if you have a strong hand, i can bid alone 5♣ 'cause my (long) suit as trump" (in this unusual bidding).

About play was possible to realize 5♣+1 if was been retained the Queen in club suit : the ending had to be N ♠ 97 ♥ 7 ♦ - ♣ - E ♠ - ♥ J ♦ - ♣ J8 S ♠ - ♥ 10 ♦ - ♣ Q10 W ♠ - ♥ - ♦ QJ8 ♣ -. If it is moving by N is a situation of pseudo Trump Coup (remaining a loser in the hand) that,although, it allowed to realize 13 tricks if E descarts wrongly heart J but it having viewble the cards of S is more difficult. In the other case by S leading heart for returning in club Q 10. This situation needs preventivate(=read) and the ♥ Q can help meaning there is not other fourth best.
