Would you guys have played this any differently? 25nl

1. I'm on the button. No reads on the villain, I just sat down.

TONY-fran checks
Ibanezrg bets $8.10
TONY-fran calls $7.40 and is all-in
Uncalled bet of $0.70 returned to Ibanezrg
*** SHOW DOWN ***
TONY-fran shows [Th] [Ad]
Ibanezrg shows [6h] [Ah]
*** RIVER *** [As] [5s] [7s] [Qd] [Kh]

Should I have checked behind here on the turn given that all I am realistically getting called by are hands that are beating me i.e higher aces and a made flush, and then call a smallish bet on the river.

2. Also what do I do here? On the button again. Villain has quadrupled up. He runs 40/8/1.55

Me????

No reads on him doing this. However, at micro stakes I have seen this overbet been used by AA (though that was preflop) and I myself have used it (at the right time of course!)
