Since you said the BB is a good, very loose reg, and the SB is weak/loose, I'd imagine the SB would have something like AK/AA, and the BB something like K10 (I'm not thinking in terms of ranges, but bear with me). Those are the only two hands that we beat that we could maybe expect to get it in.

So, if you were going to call the SB's shove, as you mentionned, I think the BB has two pairs, or maybe even A5c (because he is very loose), and that your set is good. 

However, I'm more scared of the SB's shove than the BB's call, because the SB's range includes KK and 10|10, which both have you beat.

SB's range when he shoves: KK, 10|10, AK.                                  | 27%

BB's range for calling all in: KK, 10|10, K5, K10, A5cc, 55,              |06%

You: 22                                                                                          | 67%

Of course, basing a decision upon these calculations isn't right, since it assumes that every hand in their range shows up at the same frequency, but I still think that it shows you made a significant mistake by folding your set. These ranges are based on the information you gave me (BB=lose, SB=w/L), but I'd love to see some stats, like the SB's 3b%, if you have them.

Hope this helped!

Why call the 3bet preflop w/ 22 if you are unwilling to get it in here?

well off course i did flop a set and im happy with it

but the way the action was i think i should consider folding

i think its wrong to say"ok i set mine pre...and get it in anyway regardless"

this is a rare spot where my set doesnt look too good 

also when i said BB loose ive mentioned hes good

and one thing is being loose pre..one thing is get the money here where no draws got there on the turn

also BB range doesnt have K5 ...and since we are not deep i need to take A5ss out of it as well

prob some K10 but i didnt see many of those as well...they wouldnt play well 100bb knowing i will complete a lot pre..

anyway i'll post soon the showdown

thx for the comments tho

@OP, you are right that you should consider folding but you were wrong in actually doing it. :-)

Phil Ivey got knocked out of the WSOP main event flopping set over set. Sets are hard to come by, I wouldn't make a habit of folding them. You can't win every hand anyways and if someone has a bigger set chalk it up as a cooler and be on your way IMO. (On dry boards of course, not including like 9TJ all spades or something else ridiculous.)

so i'm making a mistake thinking that at least one of the 2 guys got me beat here??

if this was a speed table, id never fold this to any of the regs in that game
