You rather need to make the right evaluation of your hand by Frank Stewart

A: 3♥: If partner has little "waste" in clubs opposite your void -- Q J 9 7 6 4, A J, K 4, J 6 5 -- you can make a slam. So you might bid three hearts, then support the spades to let him judge your prospects. An option is to bid six spades. If partner has Q J 9 7 6 4, A 3, 8 4, A K 5, only a diamond opening lead will beat it.

Your result so far:

A: 2♥: You could blast into 3NT, hoping for a friendly lead or spade help in dummy. (If partner holds A 3 2, Q 6, A K 8 6 5 3, 4 2, 3NT will be a better spot if you are declarer.) If you prefer a slow and careful approach, bid two hearts. If partner has 3 2, A 4 3, A K 8 6 5 3, Q 4, you need to find a route to five clubs.

Your result so far:

A: 6♣: Partner seems to have six diamonds, four clubs and extra values. With 3, 4 2, A K 10 8 7 6, A J 3 2, he would have rebid two diamonds. Since you have perfect cards, bid six clubs or diamonds. Partner may hold 3, K 2, A K 10 8 7 6, A J 3 2.

Your result so far:

A: Pass: Many experts would consider this hand a mandatory opening bid with its fair defensive values, but a case exists for passing. The hand has no major-suit length or high spot cards, the long diamonds are ragged and the spade honors aren't carrying their weight. I would pass, but I would open a 12-point hand such as K Q 10 6 5, 5 3 2, K 8, A 5 2.

Your result so far:

A: 6♥: Partner will usually have six good hearts with 16 or so high-card points. You can evaluate in terms of points, but a better course is to visualize hands for partner and imagine how many tricks he will take. A minimum such as 3, A K J 9 6 5, A 10 6, Q J 2 will produce 12, hence I'd bid a direct six hearts, giving up on seven.
