Maybe I should spell out the point I made jokingly: 1♠ would be a much better overcall if our 5-card suit was in RHO's opened minor suit. If RHO has a 4-card suit, we have to ruff one time less to set up our 5-card suit! It would also mean we have less defense.
To say it differently: Playing in spades we have 5 heart losers, of which we can expect to ruff one, sometimes but rarely two (if partner can ruff more than one, then he would often be able to enter the auction by himself), sometimes none (LHO can overruff an pull trump). If they play somewhere, they have 2 heart losers, which they maybe can ruff, but often not (we pull trump, or partner can overruff).
Doesn't exactly sound like a hand where we want to play 4-3 fit, or a 4-4 a level higher than the law tells us to!
I don't know who started using exclamation points like in this fashion, but it is getting rather tiresome. Does using an exclamation point help emphasize a point that cannot be made in other ways?
It would seem essential that we need to establish the 5th heart playing a high level spade contract but it is not critical in a partscore. Even if they cut down on our ruffs, we may later take heart tricks by force, or the heart pips may play a role in the endgame.
If we were 5-5 in the majors, I am quite sure you, me, and everyone else on the planet would overcall. Yet, our prospects of setting up our 5th heart are the same. Furthermore, even if our suit were a minor, we might get tapped out before this happens.
Are you really so sure that partner will be able to compete over their part score with four spades and a heart stiff? How about four spades and a heart doubleton? How about more? I think this is more problematic than you represent.
Passing ignores the lead benefits of bidding spades too. I think this is particularly big at matchpoints.
While I agree about the law implications of a 4-4 versus a 4-3 fit, the opponents must negotiate this as well, and bidding spades may get them to overcompete! (sorry couldn't resist).
