JamesBJames and Xhad, you are right, but...
concerning the outs, hero just has 3 outs to split. All other outs (4x8, 2xT, 3xQ, 1 for backdoor flush draw, 10 total) are not to the nuts and have to be discounted, let's say down to 1/2, so he still has 8 outs (3+5). I didn't consider this properly.
IMO after a reraise by SB you don't get 13:1 PO but only get 13:3 (the 3 SB you invested)= 4.3:1 and you have to take into account reversed implied odds on the turn.
What kind of player was SB? Normally with KQ you would like to slow play the flop I think and check-raise the turn or river to get more bets in.
In this new light I would just call the flop. Wether a player behind you also holds also a K can't really bother you. If you put that player on such a hand you only have to take into account that now you only have 2 outs to split. So I think it's best to see the turn cheaply and let the 3rd player in. If you hit your K you hope to get further bets from him.
