Thinkers=Bluffers???

Situation:

Early in tourney- lets say second blind elevation.

No reads on other players yet- all have been playing solid poker

I have AKs and raise 3x from button, SB calls, BB calls

Flop comes:

Kc4d3d

SB checks, BB checks, I bet 3/4 pot
SB folds, BB calls quickly

Turn:

Td- essentially a blank

SB checks, I bet pot
SB thinks and thinks and thinks and thinks then goes all in

What do you think?
1- Bluff- he has nothing and is hoping to get you out of the hand
2- monster- flopped a set or two pair and doesn't want you to draw out on him
3- Bathroom- had to go take a wiz and just made it back in time then decided to go all in with a Ten
4- Other option

This happened to me a couple of nights ago and I ended up calling his all in.

Results to come after I get your feedback (sorry for the tease but I don't want to ruin the feedback by providing you with what actually happened)

Thanks.

Bluff, but knowing the Donkeys at Ap he had a sniff of something and was hoping to suck out.

i would more than likely just throw the hand away that early in a tourny depending on the buy in. cause if u really think about it he could of hit his flush and was trying to make you think he was bluffing by going all in. or it could be a semi bluff and he has 1 diamond in his hand which would make your call a good one but do u want to risk all those chips withh the possiblity of being dead already or get drawn out on. i say the buy in matters because if its a $5 tourny that type of play will make me curious and if im on tilt i might throw my chips in thinking im scrwed. anyways i want to hear what this guy had you got me very intrigued. hmmm thinking again maybe he had flush draw and str8 draw on the turn i would definitely say u cant label the 10 of diamonds a blank
