If all your cards are live, with a straight flush kicker you have to call 3rd and see 5th street. The fact that the other guy came in is probably even better.

With all that money in the pot on 5th street you've gotta go to the river. You have a 3 straight and an overcard kicker at this point, if he has just kings you are not that big of an underdog.

What you need to be careful of here is when the other guy catches another diamond on 4th street, since now he probably has a 4 flush. If this happens u need to surrender on 4th street unless you improve greatly.

P.S.

Check raising on 5th is usually bad unless you know your opponent is a fairly good/tight player, who knows that you are a very good/tight player and has never seen u make a play like this without the hand. Usually for something like this to work you have to play with this opponent for many hours, so you should rarely be looking to make this play.
