Did the flush draw play this hand right?

[WinBig]

$50 NL Hold'em on Empire. No real read on either player in this hand. I'm relatively new to NL but I've done well at both the $25 and $50 NL tables. I'm interested in the thoughts of how the flush draw played this hand on every street.

Stack sizes for the players in this hand - seat 7 was the button:
Seat 1: Villain ( $29.5 )
Seat 4: Flush Draw ( $95.42 )
Seat 6: HERO ( $165.4 )

Dealt to HERO KhKc

Villain raises [$3].
Flush Draw calls [$3].
HERO raises [$12].
Villain calls [$9].
Flush Draw calls [$9].

I assume that Flush Draw called here since he was getting 3-1 odds on a hand that could hit big with the right flop. I think my raise has represented a big pocket pair which is what I wanted. Was my preflop raise too big? Should I be happy to take the pot right then? Is this a standard call by Flush Draw?

** Dealing Flop ** [ 7d, 6d, 8c ]
Villain is all-In [$17.5]
Flush Draw calls [$17.5].
HERO is all-In [$153.4]

I thought my reraise would get FLUSH DRAW out of the pot but I guess he was priced in getting 2-1 on a hand that will hit roughly 50% of the time if he correctly assumes he has the nut flush draw of the three players in the pot. Is the all-in call correct? I have pushed all-in when first to act with a K high flush draw and two overcards but I have some folding equity in that situation.

I guess my question is should I be making calls like this to increase my win rate? Risking $66 to win $218 with a 50% chance of winning seems like the right move. Thoughts?

Villain shows [ Ks, Ah ] a pair of eights.
Flush Draw shows [ Jd, Qd ] a flush, queen high.
HERO shows [ Kh, Kc ] two pairs, kings and eights.

I'm not the best odds expert on this forum... but the flush draw is, at best, %38 favorite. If all three players were all in, I think his gamble would be ok. (this doesn't include the times when there will be a higher flush or if someone gets a boat)

If he knew you were going to reraise, I'd say he wasn't getting good odds.

raise more preflop, flop looks good, his call is probly ok also.

yep, he was marginally correct to call that. I've made the same call when I played lower limits but these days, I wouldn't just because the variance is a MF . I guess he doesn't mind it but he will once he misses 2 or 3 all-ins in a row.
