1NT (1) 2 ♠ ???

(1) 12-14

For a change I am not presenting an error but a good result.   The bid I made was 3 ♣ and that worked out well.   I think it is a good bid, even though it forces to game.   A minor suit fit seems a certainty because the opponents will have at least 8 spades.   With a minor suit fit you have about 14 support points, so you reach the 27-or-so combined points needed for 5m.   After my 3 ♣, partner bid 3NT and that ended the bidding.

Partner had ♠K104 ♥KQ85 ♦J4 ♣KJ76, so 3NT is in danger if they take their 4 diamond tricks and the ace of spades.  

I was playing the hand versus the computer so even as dummy I had to play the hand.   The lead was ♠A, 7, 6 and I "encouraged" with the 10 since the opponents play high=encouraging on partners lead. East continued spades so we had +430 and 10 IMPs.  

I note that 5 ♣ is down, losing a spade and two diamonds.   Is 3 ♣ a good bid indeed?   The hand is from a "competition" I am doing with the latest version of computer bridge playing program Jack, version 4.0, I just received.   I selected English Acol as bidding system for me and my computer partner.   But it advises Pass, not 3 ♣ here.   And Jack is supposed to be pretty good.   East had ♠AJ9852 ♥742 ♦KQ98 ♣-, so a diamond switch is not really impossible to find.  
After 10 or so -1 to +1 scores in the match this one was the first big swing.
