6. Not sure, but trying to show my hand
Giovanni Donati (ITA) Pass
I pass, not enough values to bid 6after partner’s preempt.
David Bakhshi (ENG) WIM: 6
6 – Could be that we can make a grand slam or that we go down in 5, so could even be best to defend 5x.
However, I would hope we can make at least a small slam and try 6on the way to 6.
Krzysztof Martens (MON) WGM: Pass
Brian Senior (ENG) WM: Pass.
Pass, in tempo, and maybe opener will double??? It is a guess with 6possibly being cold and posibly being no play. I’m a pessimist when partner makes any pre-emptive call.
Benjamin Robles (CHI) WM Pass
Pass. it seems automatic in these colors. If there is slam it is impossible to know without space, I prefer 400 insurance and the possibility that they still reopen with double.
At all nil, KQJ to eight clubs and 8221 shape with nothing special is just a 4bid, so I expect eight good clubs plus something extra. That extra could easily be a spade void, in which case even 5could be going down (e.g. – xxx Qx KQJTxxxx is possible to only make ten tricks). 
we have good chances, and if not opponents might miss the lead, but that’s not necessarily enough.
Pass. Partner appears to have his side suit cards, particularly honors, in the diamond suit. In order for slam to be good, even a nice diamond holding such as KTxx to complement KQJxxxx in clubs does not suffice: we lack the ruffing power. As even an 8-4 distribution does not nearly guarantee slam, it just can’t be good enough.
