The Quick Call ???

[Nomar]

Okay I was playing 3 handed 1-2, mega fish, me and Jdags.

I open in SB with AK, JDags 3 bets from BB I cap, flop comes 7-4-2 rainbow, turn 8 spades, making 2 spades, I bet he raises, I call (kinda quick) river non spade small card, I check he bets, I think, think and reluctently payoff, he has 9-10 for 10 high...MHIG

when talking about this hand with a friend he said "Call the turn real fast" then if he bets the river he has it so I can fold, but if "you think on the turn you have to call the river."

My question is instead of doing this quick call on the turn I have heard so much about, isnt it better to do the slow call and always pay off ? Heads up in the blinds with an agressive expert it cant be that wrong to always go to showdown with AK, and the slow turn call will entice him to always fire the last barrel.

is my thinking waaaay off here ??
