Thanks for all the input folks.
I've definitely come to the conlcusion that this was a bad play by me and glad it turned out the way it did or I'd probably never looked at it again.
The result was :

River

So despite getting desperately unlucky, I think the only way this hand wasn't going all the way would have been a bigger pre-flop raise.
Oh and I am dropping the check in the dark - Maybe a first post flop bet may make them think AK....
You seem to be a bit results oriented in your thinking. It was mighty fine play, in a vacuum against this particular opponent. Look how bad you got his money in pal!!!!
You played it optimally, you got all his money in drawing to 5 outs. Thats pretty much christmas in the poker world.
