10/20 RSD(15/30 cents) Last hand of the night, 7-handed table was weak all night, apart from one very good player who left earlier. I am sitting on 5900, and have pretty much everybody covered.Straddle was on for 40
Action: call, call, CO goeas all in for 800 without looking at his cards, button folds, I look at KcQs

What do I do?

I moved all in but am starting to feel that that was an -Ev move

Any elaboration appreciated

I forgot to say that I am in SB

high variance move with the people behind left to act. i'd prefer a call before a shove though, just in case someone decides to gamble with A9s or something.

that said i'd probably just fold and rack up, forget about a 80bb swing (at least) against a blind shover who gave up position in order to gambool it up.

I think shoving is mandatory considering you're basically last to act preflop behind BB and the straddler. I don't imagine the limpers have a limp/reraise range a lot unless they know the straddler is known for defending his straddle pretty liberally. KQ is 62% against a blind shove and there's a decent amount of dead money. Even if someone wants to gamble with 99-JJ you have overs and you'll probably scare away AQ, AJ type hands although I think AK will find a call.

Thx for replies,

Now, here is how the hand finished, BB folds, straddle calls for his all in 1880, the rest folded.
Board
10c 8c 4c 10d x
BB tables A 10 off , CO, mucks and I tap the table

The right play depends upon the shover's image. For example, if he let everyone know he was shoving blind before the hand was dealt, or if the limpers had some clue that he was going to raise before they limped in, then this is a clear fold. You aren't worried about the guy shoving in this spot, you're worried about the limpers who might be trapping.

On the other hand, if the guy just shoved blind out of the blue since it was the last hand, then you should probably min raise. By min raising you shut out the limpers from calling without strong hands. If you just call they will probably come in with pocket pairs and Ax hands that you would rather see fold. If they come over the top of you you're likely way behind, but the stacks are deep enough that you can fold without wasting more money.

Just my opinion...

This is really close but it seems to be slightly +Ev call.
You have 61% equity vs the blind allin shove. And if one of the limpers call
with 22-JJ,A2-AJ you have about 36% equity 3way (with some dead money
in the pot), so that should be abouzt enough for the times
that someone slowplayed AQ+,QQ+.

@moneyline : Funny thing - He did let know the table before the cards were dealt that he is going all in, and still the limpers folded when the action got back to them. Although they faced two more all ins prior to that so that is maybe why.

I see different opinions here on what is the right way to play this hand, but overall my take on it (after reading all the answers) is that it is a high variance move if I put money in any way(call, minraise, shove).

Since I am trying to reduce variance when I can, I am gonna incline in the future towards folding here. Let's say I still want to have some idea of range with which I would shove or minraise with more advantage on average against a blind shover and people behind me.

What should that range be?

I am thinking something like: TT+, AJ+
