This is is more of a generalized discussion of the best play for maximum value and minimum variance, though I will be showing a specific hand.
Game is Commerce 1/2 blind game ($40 buy in, lol).
Profiles and stacks:
SB - $130 - old Asian gambolor, crazy action.
BB - $120 - hero, probably a TAG most of the time.
UTG - $20 - donk fish
+1 - $120 - good lag tag, most solid player at table.
The rest: about $40-$60 stacks, typical loose passives.
UTG goes all in DARK for $20.
Then HERO is dealt K
K
in the BB
+1 calls 20, two more callers, SB raises to 60. Hero goes ALL IN for 120.
Now, let's discuss the merits of shoving here versus flat calling the 60 and then shoving any non-ace flop.
When we SHOVE, we are trying to be heads up against the Asian guy. Asian guy has TT+ and AT+ in this spot, though might be tighter like JJ + and AJ+. All the other players probably have small pairs, connectors, any suited, etc.
If we are all in PF against Asian guy with his tightest range of JJ+,AJ+, then we are at most a 2:1 favorite as he gets a five card flop:

(Equity, Win, Tie)
Player 1: 2.03:1F 1.93:1F 46.4:1 [KsKd]
Player 2: 2.03:1 2.13:1 46.4:1 {JJ+, AJs+, AJo+}
Board: [? ? ? ? ?]
Deal To: River
Though in this scenario there is 120 in the main pot (three way) and 200 in the side pot (HU) (we risk 20 in the main and 100 in the side.)
Our equity for the main pot is 56%. (Side pot equity is 67%)
PokerCruncher-Advanced-iPad V.8.2.1
(Equity, Win, Tie)
Player 1: 56.6% 55.8% 1.76% [KsKd]
Player 2: 28.9% 27.9% 1.96% {JJ+, AJs+, AJo+}
Player 3: 14.5% 14.2% 0.73% [??]
Board: [? ? ? ? ?]
Deal To: River
So 100*.56 + 100*.67 = 123. We lose 20*.44 and 100*.33 = 41.8
so our
EV is 81.2 with this line.
Now let's consider if instead we FLAT CALL the raise from said nutty Asian guy., with the plan for shoving our remaining 60 into any non-ace flop.
At least two of the other callers call when we flat the Asian guy. At least one of them ends up all in so we have two all in players to the flop (and now a main, side, and potential additional side pot).
The main pot is still 120, and the side pot is now 160 (200 if everyone calls) seeing the flop. Probably one more person is all in so further action will be in a second side pot. At the moment we have 20 into the main and 40 into the first side pot.
In this scenario we are 1.8:1 to see the flop (not counting any further cards). This is 65%.
21% of the time there is an ace on the flop and we check fold.
79% of the time we shove. We get called by top pair hands, some draws, and of course hands that beat us like sets and two pair and flopped straights.
Of the hands we shove and are losing immediately 14% (though we draw out on some of these around 30% of that 14%, so our loss is actually 10%) and the hands that call us when we are ahead draw out around 30% to 40% of the 65% which makes our wins 40% to 43% + the 4% we're behind and draw out.
We lose our flat called 60 the 21% we check fold an A high flop.
We lose our additional shoved 60 the 10% we're out flopped and the 22% ~ 25% we're outdrawn assuming no one folds their draws (and they would be wrong to fold any 4 out or better draw as they would be getting better than 5:1 on the call). But let's assume that gutshots fold, bottom/middle pair draws fold (I.e. 4 and 5 outters)
When we are called by a TPTK hand and a flush draw, then, we have to dodge about 14 outs.
Crunch of our flop equity:

Thus we lose 60 about 21% of the time we check fold an A high flop.
We are called by at least one player that out flopped us 14% of the time, which breaks down to:
- We lose total 120 about 10% of the time we shove but we're out flopped and we don't redraw.
- 4% of the time we profit about 220 when we were outdraw but we hit our redraw.
But even when not out flopped, we still may get calls from one or more players that hit top pair or a draw. For this argument, let's say that 50% of the time all fold (except two all ins) 25% one call and 25% two calls. Also, we'll group the below estimates within the remaining 65% of events not listed above
- 50%: We win 160 about 72 % of the time (everyone folds to our shove and we are left with two others all in)
- 25%: We win 220 about 48% of the time when there are two all ins and one player calls with a big draw.
- 25%: We win 280 about 39% of the time that there are two callers to our shove (top pair and a strong draw) and two all ins.
About 5% to 10% of the time we only win one or both side pots, so we subtract $15 from these numbers.
145*0.5*0.72=52.2
205*0.25*0.48=24.6
265*0.25*0.39=25.8
=102.6 (won when called by draws)
-120*((.5*.28)+(.25*.52)+(.25*.61))=-50.7 (lost when drawn out by draws)
Totals:
-60*0.21 = -12.6
-120*0.1= -12
+220*0.04 = 8.8
+102.6*0.65= 66.7
-50.7*0.65 = -33
EV = 17.9
---------
Of course, the second line of action is full of estimates, but the upshot is that we let in a lot of other people and that substantially reduces our chance of winning.
21% of the time we cut our variance in half when we avoid an ace on the flop.
But 79% of the time we become a coin flip against 2,3, or 4 opponents.
In short it's better to be a 2:1 favorite 100% of the time than a 1:1 coin flip 79% of the time.

WHY THIS POST
If you are wondering why I am posting this, it's becuase of the above hand last night. I was wondering to myself if it's better to get all in PF and give Villain a 5 card flop, OR to wait for a flop and then shove into several players.
Rather than guessing I wanted to work it out, and did so in the form of this post.
All comments and further discussion appreciated.

CLIFFS NOTES:
Yes, is best to ship it in PREFLOP and NOT go for overcalls here. While the final pot may be 80 to 160 SMALLER (20-40% smaller), you are more than twice as likely to win.
Even though you reduce your variance by $60 21% of the time, you increase variance by 50%, 79% of the time.
LINE 1 (PF shove) we lose 120 about 35% of the time. We profit 200 65% of the time.
LINE 2 (flat and shove flop, fold ace flop) we lose 60 21% of the time, PLUS still lose 120 35% of the time. We profit ~300 only 44% of the time.
