NL25 - Bluff? What he could hold here

[AKQJ]

I just sat down 2 hands ago, and he was the biggest stack at the table.


Full Tilt No-Limit Hold'em, $0.25 BB (6 handed)

SB ($46.35)
BB ($30.70)
Hero ($25.40)
MP ($26.20)
CO ($22.20)
Button ($25.65)

Preflop: Hero is BB with J[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">3 folds</font>, SB completes, <font color="#CC3333">Hero raises to $1.5</font>, <font color="#CC3333">SB raises to $4</font>, Hero calls $2.50.

Flop: ($8) 8[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets $5.25</font>, <font color="#CC3333">SB raises to $12</font>, <font color="#CC3333">Hero raises to $26.9 (All-In)</font>, SB folds.

Final Pot: $46.90



After this hand, he said something like "thanks you for reraising all-in, I knew I had to fold. If you just called, I was going to move you all-in on the turn"

Probably no. He could say such thing to fake up his hand after a missed float/squeeze play against me with total air. Probably yes if he was honest, if he is holding KK or AK

What's your guess?
