[GinoNZ]

Auckland Casino 2-500 100/200NL

Delt to hero 4C 7C on the button. Limped around to bb with 3 limpers.

Flop J5J

this guy who likes to bluff alot and be a HERO type player leads out for 15 ,folded around to me. I'm thinking of smoothing and try to take down the pot either by bluffing or by hitting a flush.so i call.

Then turn was 6of dimaonds. So gave more outs. He leads out for 45 i call. ( i think raising here is better then leading the river). River is the Ace of spades he checks

and i bet 75 and he calls after 5mins of thinking. If i go Ai he going to call. I had 300 behind and he had about 250. He called and showed KJ. Do you think betting 110 is better.

Or this anyway i can even win this hand? or was it just totally crap.
