Scoring: IMP
P - (P) - 1♦ - (1♠)
2N - AP
Do you agree with 2NT? Probably not, but anyway, you have to play it now on the ♠Q lead while RHO follows with the ♠2 (UDCA).
Continuations: If you win and play a diamond, the ♦K will hold as RHO plays the ♦T. If you play a heart back to your ♥Q, that will also hold.
If you duck at T1, LHO will continue with the ♠7 and RHO will win the ♠A and switch to a low heart, and your ♥Q out of hand holds.
