hey guys, I'm hoping for an answer from some of the expeirienced players out there, but anyones opinion is valued

NL .05/.1, full ring game
I'm dealt Kd 9d on the button

folds to me, I limp in. SB limps, BB checks
flop:


SB checks, BB checks
i bet the pot (30c)
SB fold, BB calls

Turn:

BB pushes All in

now heres my question, did I read this correctly?

ok, so if he had A4, A3, A9.. he's strong with 2 pair, theres 2 possible flush draws on the board, so he'd be betting, roughly pot size bet. he'd be pretty confident he's holding the best hand so he's happy for me to be chasing. so 2 pair wouldnt push here. that rules that out.

Ax.. no preflop raise, so not AK, AQ, and probably not AJ, A10, any other possibilities, probably not, i dont think this guys a complete idiot to stay in hoping to hit that magical A. and even if he did, after i've shown strength is he going to want to drive me out and win less money from me.
so I'm thinking he hasnt got an ace.

25 has just hit a straight, but that still wants those chasers to pay him off, theres no all in from him. not in a 90c pot (all in for $8). so no straight.

99, 33, 44. this guy reraised sizable raises with 55 and 22. and was prepared to go all in on them preflop. so i'm not putting him on any pp, and even if he had made a change and limped one, if he's caught a set he's the same as 2 pair/straight.. he still wants a caller, he wants to bet and be raised and get all in, not push right there.

so after all this thought i decide that about the only thing that would push there is a stone cold bluff, or a flush draw/straight draw, ie. semi bluff.

so i call, he has .. no straight/flush draw, stone cold bluff.. 5 outs to beat me.

so does my thinking make sense or did i get lucky that this time he was bluffing?

extra note: he rivered a 10 damn him
