This is a difficult choice. Bidding game depends upon how much value you place in a void in your partners first suit, and how useful you think the queen of hearts will be on this auction. As we see, opinions are highly variable from the polar opposites of leap to game to bid a cautious 2♠, with a number of middle of the road bids that will get you to 3♠ with a chance for four.
The bottom line, however, even if you invite, is that game will likely make or not make on based upon how useufl your club void is. How might you quantify the bidding choices from 2♠ to 3♠ to 4♠? Well, if you use ZAR fit points (will not really help you here btw) you could justify each of bid. Let's see how.
1) Zar counts hcp (8 in this case), plus two points for each card in your longest suit (10 for five hearts), plus 1 point for each card your second longest suit is longer than your shorest suit (4 for 4S - 0 clubs). Then 1 point for each "control" sof that is 2 more for the diamond ACE, plus a point for each AKQJT in partners suit (but never more than 2), so 2 more for QT of spades. Base ZAR points in support of spades is 26 points.
2) The Zar theory is that you need 26 to open and 52 to bid game, so here with your 26 opposite your parntes minimum 26 you might should bid game, but wait there is more.
3) Positive Zar fit points also apply, here the void in clubs and four spades is worth 3 additional fit points, raising the ZAR count to 29. Easy enough "value" for game. IF you count ZAR points you bid game willy nilly here.
4) However. experience (as reflected in Justin's comments above) show that voids in partners first suit are not necessarily a good thing. Zar recommends subtracting points for "inadequate support" for the trump suit, but you can (and should) also figure out a negative value for bad support for partner first suit. So the question becomes how to apply this subtraction here on this auction. If parnter is 4-2-3-4, you really don't have to worry that "clubs" is his first suit. If partner is 4-1-3-5 you do have to worry about it. So the question becomes how much negative is the void in partners first suit. If you use the 3 points per card less than three, void in clubs can count for a MINUS 9 zar fit points. This reduces the count to 20, so a simple invite with 2S is more than enough. I wouldn't use 3 points per card in a suit that wasn't trumps, as that is too much. I use a sliding scale, with one for the first short card, two for the second, and three for the third. So here, the amount off would be 6 points. This gives you 29-6 = 23 ZAR points, enough to invite game at the three level. IF partner has a king more than minimum (hence 29 himself), he will bid game.
The real problem, as noted above is how to evaluate the void. If your partner will rebid 1♠ over 1♥ anytime holding four spades, being vulnerable it is probalby best to ignore that he might have real clubs and blast game. If he will rebid 1♠ only with "unbalanced" hand pattern, then it is best to invite game. In fact, in this later case, I will issue only a mild invite of bidding 2♣ --) transfer to 2♦ and then rebid 2♠ (which is weaker than immeidate 3♠ jump or 2♣ followed by 3♠). The deciding factor is not only the void in partners suit but also the questionable value of the heart Queen.
Another way to look at it if you are not a ZAR fan and haven't experience to evalute this by feel is cover card concept. Assume your partner has 7/8 loser hand at most, how many cover cards do you have? Diamond ACE, SPADE Queen are two. Heart queen is 1/2 at most. So how many is the void is clubs worth? One? Then invite game is enough. 1.5? Then strong game invite. Two full cover cards? Then jump to game. In Ron's example hand. The heart queen was full cover, and the void was at least two covers. so game made easily. Change his two red kings to AK of clubs with same pattern and even 3♠ is in jeapody.
So bid game, strong invite, mild invite? It all depends upon your evalation of the void in clubs... experience, Zar points, cover cards, none of them will really help because what you need to know is almost unknowable. I use the following xyz auction to show this kind of responder hand... 1m-1H-1S-2N-3C-3S as game invite with short in partners first suit (to separate from 1m-1H-1S-3S and 1m-1H-1S-2C-2S-3S... the first is good invite based upon distribution not short in partners first suit, and the second is good invite based upon hcp values. (NOTE, I use 2NT in xzy to signoff in clubs at three level, or for a variety of invite hand types to separate the difference between jump rebid of 3H or 3S and a 2C rebid followed by 3H or 3S).
Anyway, any of the bids can be right on this one.
