ok thanks for all the advice guys.. heres the result.. wich i was utterly amazed at, he was a complete fish,

so i pushed AI for $15
he though for his whole time.. and then called.. at which point i thought ok that was a pretty big call, i'm probably beat
River was a second 8, making the board 38948

He turns over A2

now explain the reasoning for his play for me and i'll eat a fridge

in reference to some of the questions put up, i didnt have a strong player read as i'd only been in at the table for a few hands.. probably a bad time to make a move just based on the reason.. and i had position on him.
