$50NL 3Bet AK OOP........Boring

[Spanky1974]

I almost never read the AA and AK hands here, but I have just started 3betting PF from the blinds with unpaired hands. No reads on Villain. PokerStars No-Limit Hold'em, $0.50 BB (6 handed)

CO ($50)
Button ($28)
Hero ($58.40)
BB ($82.90)
UTG ($76.10)
MP ($20)

Preflop: Hero is SB with K/images/graemlins/heart.gif, A/images/graemlins/club.gif. CO posts a blind of $0.50. MP posts a blind of $0.75.
<font color="#666666">1 fold</font>, MP (poster) checks, <font color="#CC3333">CO (poster) raises to $2</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $7.5</font>, <font color="#666666">1 fold</font>, MP folds, CO calls $5.50.

Flop: ($16.25) 7/images/graemlins/heart.gif, 6/images/graemlins/spade.gif, 5/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $12</font>, <font color="#CC3333">CO raises to $42.5</font>, Hero?

3bet and cbet amounts OK? I don't think I beat much here. Any better lines?

[_TKO_]

3bet amount is fine. I normally go $6-7 for a raise here. Flop bet size is also fine. It looks like CO has at least a pair here, obv can't call the raise.
