Can't figure out how to copy anything from Bovada.

He limped in so I checked pre-flop.
On the flop he bet 5 so I raised to 15.
On the turn I bet 25. He calls.
On the river he bets 50. I raise to 170.

I didn't think an A8/9/4 hand would be limping in like he did so I figured I had the best two pair.

don't assume those hands won't limp first off because those are exactly the type of hands people limp.
