i have KQs diamonds UTG and raise to $10
one caller and gets to SB who raises to $20 and he has me covered
i call and so does the other player
flop comes 9T3 with two diamonds
BB leads out for $60...
First raising this hand UTG is playing it risky. You're going to have to hit your flop hard. This is mistake one. The raise in my opinion should be a little lighter. Maybe $7. As we see it is re-raised but by the SB, thus putting him out of position the rest of the hand. The SB should be opening with a pretty decent starting hand from this spot and situation. You just called which I would call mistake number two. You represent a big hand from UTG when raising and should be raised again. You'll be in position playing the blinds for the rest of the hand and thus this is why another raise pre-flop should be considered.
Anyway you called which isn't by in means wrong. You have got the right
odds to call. The pot is $60 and I'm assuming the SB checked and the BB made the pot sized bet. (I am lost a little in this hand). So $120 in the pot so far and you'll have someone to act behind you that raised pre-flop. You haven't hit anything with this hand, you're getting 2:1 on your money. You have 9 outs for a flush, that's not the nut flush, and 4 outs for a gutshot straight. You don't mention which cards are diamonds but if its the 9d10d then you have a straight flush draw but changes nothing. Shoving here is a mistake unless you're sure your opponent has nada and you know that he'll fold to a shove. He made a pot size bet so he hit something that needs protecting or he bet his own draw. AA, KK, AT, TT, 99, QJ & 87 seem to fit the range easily. Also some odd flush draw maybe in the range as well especially AdXd. I would fold or just call here. I have shoved in this situation and when it doesn't work then I just feel like a misplayed the whole hand. If I hit then I feel I got lucky. If you got your jack and made your straight then you also have to consider that he has AdQd and it has given him a few more outs. I'm not shoving here but just calling since we didn't re-raise again pre-flop. Just my insight, I hoped it worked out for you.
I'm still a little thrown off. because you said SB and BB. I don't know if your meaning the same player?
