Likely you would have bid this more slowly, but you don't have solid agreements about the meaning of 2/2 in this partnership so you decide to blast. Note that the contract is normal in any case. LHO leads the T (standard leads). What is your plan? IMP teams if it matters.

It would be fun to give West's hand as a defensive problem looking at

36% of the time will break 3-3 and the contract will make.

48% of the time will break 4-2 and 33% of the time the club jack will be in possession of the person with 2 clubs, giving me a 16% chance there.

That gives me a 52% chance of making the contract. Not the most glamorous odds, but still nothing to scoff at.

Cover the heart and win East's honour with the ace. Unblock the club and play a low spade.

The defence will usually win and play a heart. There are various possibilities, but say East wins the spade cheaply and returns the 2 and West wins and switches to a diamond (likely). Rise with the ace and cash clubs. If they don't come in, you still have chances in spades. Throw two low red cards and lead a spade up, hoping for Axx onside. The defence now have 5 tricks, but no way to reach them. And you have 3+1+2+3 for 9 tricks (if East is 3262, he may jettison the spade ace on the third club, but more likely he is 3244).

They can counter by switching to diamonds without cashing a heart, but you have to give them a chance to err.
