sam farha vs. (unknown) day1 wsop

So my brother and me were talking about this hand.. and we couldn't figure it out.. so i came here [img]/images/graemlins/smile.gif[/img]

Basics:
1. Farha has 22,000 chips approx. and uknown has 10,000 chips approx.
2. Uknown makes it 1,000 to go when blinds are 25-50 (20x the BB) hes in EP (he makes it fairly obvious he has AA/KK)
3. sammy calls in MP with 33

Normally you would call a normal raise with a small pocket pair and hope to catch a set or maybe just sneak in MP/LP with a call. There are a lot of ways to play medium pocket pairs.. im not here to discuss that.

What im wondering is do u think sammy's call was correct? The way sammy plays.. it probably was fine in his eyes...

The question to everyone who doesn't see like every flop like sammy does, is was this an ok play?

Some of the points that we stated are as follows:
although the preflop odds are 7.5-to-1 against flopping a set... assuming farha knows(he probably does know..) that this idiot(is he?) just told everyone he has AA or KK. Farha called about 5% of his stack to try and connect on a 7.5-1 chance he would flop a set... assuming farha wouldnt call another bet after the flop... since the guy did bet fairly large(maybe pot size? or 75% of the pot.. i dont remember..) So implied odds come into play here because the unknown is most likely not folding his aces to any flop with a small exception to like 10JQ all suited and not his suit. So sammy put in 1,000 chips to win 10,000 chips i think.. and in my opinion i think his play was fine with me... because not only does he know what the unknown is holding.. he has the right implied odds to make the call... Anyone else add on anything here or correct some stuff?
