Question 1: You are holding K♠Q♠. What is your preflop equity against an opponent who has 3♦3♣? How does the equity change on this flop: J♠5♦3♠?

Our equity drops almost 1/2
Question 2: What would you do in the following hand?
No Limit hold'em $2 (9-handed)
Players and stacks:
UTG: $2.00

5 folds, Hero raises to $0.08, BU calls $0.08, SB folds, BB calls $0.06.
Flop: ($0.25) 2♣6♦3♦ (3 players)
BB checks, Hero checks, BU checks.
Turn: ($0.25) 5♣ (3 players)
BB checks, Hero bets $0.22, BU raises to $0.44, BB folds, Hero...?
Well, we face 2 situations here:
1. The villain just hit a straight or is playing the draws, considering we have a clean draw we have 9 outs, 4:1 odds. Our pot odds are ~4,13:1, easy call.
2. The villain has a set, in wich case we have to discount the 6♣ and the 3♣ giving us 7 outs and 6:1 odds... we can call if we think our opponent is loose enough and will put more money in the pot.
We could consider our overcards and a 4 as extra outs, but I don't really like it 
Question 3: Do you have questions about your postflop play? Post your hand for evaluation.
I have question about how I played this KJo and about this ATs with a Nut Flushdraw.
