£2/5 Did playing the bigger game affect my thinking?

[mrpinkmcpink]

My usual game on the cryptos is £1/2 but I was taking a shot at the £2/5. I dont have much info on my opponent, although he recently got stacked with a QQ overpair against a flopped set. Otherwise he's running at about 22/11...

Crypto £500 NL 6 handed. Villain has £500. I have him covered.

UTG limps. I raise to £25 with T[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/club.gif[/img]. Villain calls behind me. UTG folds.

Flop (£62) 7[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/spade.gif[/img]
I bet £50. He thinks briefly and calls.

Turn (£162) 4[img]/images/graemlins/club.gif[/img]
I bet £150. He thinks and calls.

River (£462) Q[img]/images/graemlins/diamond.gif[/img]
I think and check. He thinks and sticks in his last £280 in.

Should I call here? What range do you put him on?
