3/11 players cash in this SNG
Payouts are 3rd:$50 2nd:$90 1st:$180
Stack sizes:
HERO: 10 bbs
sb: 15 bbs
bb: 8 bbs
We are three handed and I look down at K3o on the Button.
The sb and big blind are recreational and folding to shoves way too frequently.
I estimate that the sb will call 10% of hands in this spot and the bb will call about 15% of hands.
What is the best play with my hand in this spot?

I'd jam this if villains were calling at the correct rate - given your reads it's even more of a jam.

Should this really be in the MTT SNG forum?

Jam

Fold. Why jam in this position? Someone would really have to really explain this to me. @ opponets one who is short and looking for a moderate hand and youre shoving into the big stack. This is clearly a fold.

AGAIN-Just tell me why shoving is good from someone.

Im still trying to understand this myself so im going to try and explain it using words not software, probably incorrectly.

Both players are calling very few hands, and OP said they are calling even less than normal.

So they are probably only going to call with very good hand hands, lets say top 20. Assuming this they will fold 80% of the time. If when they do call, you are still going to have a chance to win. If they call with a pair other than AA, KK you can still win about %30 of the time by hitting a King. If they have Ax you are winning about 30% of the time, and if they have two middle cards you win about about 55% (i think)
Assuming my numbers are correct which I am sure they are not since this is coming from the top of my head. 8/10 times they just fold, 1/10 the call and win, and a little less than 1/10 they call and you win.

So...yea, make any sense?

if both call with 20%. So odds that atleast one of them calls is: 1 - 0.8*0.8 = 36%

I think this is a pretty big fold. unless villain are uber nits. K3o does so poorly against their calling ranges.

easy fold even if they pay with 10%/8%.

I'd fold, if they are playing badly they also will on later hands. You'll be able to cut one of them up if you get HU against them.

I'd also like info on how much they are shoving.

Maybe a shove K3s.
K3o is def a fold. There's many better hands to steal.

Are there antes in this structure? If not, it looks like around a break-even play given your reads. If both players are recreational and you have a skill advantage, it is a spot we can maybe consider passing up a small edge in favour of finding much better edges later in the game.
