someone make sense of this for me please (LC)

hey so i'm playing the 2/5 at the borgata... i'm just wondering if someone can explain this guy's thought process to me. after losing 20k+ in 3 big pots going in as the massive favorite in the 10/25, i just had to laugh at how bad i was running. after this hand, i burst out laughing for a good 10 minutes because it was perfect. three times i had made a baby flush on the turn and had a 4th flush card come on the river. anyway enough bad beat moaning... please someone make sense of this for me, or just have a good laugh.

the table is giving me no respect as i've literally come from the must move and blown 200 bucks being compeltely crazy real quick...

a guy with 1k+ (i have him covered) raises to 15.. i call with 9 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/spade.gif[/img], one other caller.

flop comes K [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]

he bets 25, i make it 75. he calls.

turn is 8 [img]/images/graemlins/club.gif[/img]

he checks i bet 150 he calls

river is 4 [img]/images/graemlins/spade.gif[/img]

he bets 300, i shake my head and fold. he very proudly tables A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/heart.gif[/img] and for the next 10 minutes the table chatters about how badly i got outplayed. i proceed to want to kill myself.

question: which idiot play did he make? did he call without odds to draw to a draw he didn't even have just to bluff? or did he think he have the best hand then bluff the river anyway? or was it something else?
