A home game poker AQ hand, and a few questions!

[Kaz The Original]

I have around $450, villian had maybe $250. Blinds are $.25/$.50 Yes, you heard me.

Villian is mega fish most of the time, huge donator. Lost $600 last time he played. While this game is nominally $20-$50 buy in, we make special rules for him. He can by in for whatever. Unethical?

So he busted, I loaned him $200 (common practice for players to loan other players money) and this hand comes up. He's playing fairly tight post flop, but has played every hand preflop. Mind you it's three handed, and I've been raising almost every hand preflop as well. Usually this is +EV in the situation we're in, because he is normally a pay off machine, but he's actually playing really well right now (better than myself).

I raise to $5 (yes, 10x big blind). This is MY standard raise right now at this point. Tightie-McTight folds, and Brad the Bold calls.

I'm unsure of the position's, but I believe he is in position.

Flop comes A94 rainbow. I bet $5, he calls. This means nothing.

Turn comes 6 completing the rainbow, I check, he bets $10, I check raise to $30, he calls.
River comes a 4, I check, he bets $30 with confidance, I call.

Any other way to play it?

I'll ask the questions later.
