Quick question on implied odds

[Brocken]

My brain's quite happy working this stuff out when I have a template to work from but the initial turning-the-problem-into-a-template confuses me. It's a fairly simple question but it's something that I'd like to bring into my though process while playing hands.

I have a set and I'm absolutely sure I have my opponent beaten at this time.
I've put him on either a four flush or two pair or some other hand that is good but not as good as mine.
I give him a 60% chance of having the flush draw and 40% chance of having another good hand.
There's just the river card to come.
There's $100 in the pot.
I have position.
I'm obviously raising any bet if the flush card doesn't come.
I'm willing to call anything up to 3/4 of the pot should the flush draw hit.

How much do I need to bet on the turn in order to offer my opponent unprofitable implied odds?


Also, could you point out any flawed thinking in that please [img]/images/graemlins/smile.gif[/img]
