I would make my 3 bet a little bigger pre and i am always c betting the flop.  Obv a horrible flop for u, but you have to rep the A, if u get a call and he checks the turn, check behind and revaluate the river. He may have a pair like 99s or TT here and prob wont fold to one bet, so you may get to showdown if you cbet the flop and turn and river go check check.

There's no doubt that c-betting this flop with KK will be profitable, it will be profitable with any two cards vs most players. But if your willing to commit those chips to the pot, surely it has to be more profitable to check behind the flop with the intention of calling a turn bet. The same amount of money goes in the pot (,more or less), except now there are so many more hands in his range that we are ahead of, maybe he's taking a stab with a small pair thinking it's good, or semi-bluffing with QJ.
Who know's what he's got, his range is obviously really wide, and I think that's the reason alot of players don't like the line I'm suggesting, they hate to have to “play the guessing game”, but the important thing about this line is that by checking back the flop we give him the opportunity to bluff, while controlling the size of the pot if we're beat.
I think you played this hand fine up until your fold on the turn Hapetimes. I would call here with the intention of making a soul read on the river based on what I think he's capable of, timing, bet sizing, etc.

I dnt like checking back the flop – firstly at least by c betting u have a chance of winning the hand there and then, and i think u gather more information from c betting and getting called than checking the flop and calling a turn lead – and if u have to play the guessing game on the river i prefer c betting flop and checking back turn approach

with you getting the first hand, I would assume you have no reads on anyone at your table. I would prefer not the 3bet, I would have called, cbet the turn. There were two clubs out and an A that hit the flop. Not the greatest flop for a KK. The cbet would give you information of where your K and you K be on the turn. I would expect that Villian's line with the “check” would be a TT+, Ax+ or meh possibly a flush draw. I like Cbet sizing to be 1/3 but I have been off the mark saying it is too small.

I take your points Danny and understand what your saying but i would  still find it hard to stop myself leading the flop and giving the initiative to the villian ! Im struggling to understand what i would do if the flop goes check check and he leads the turn considering my stack size. Perhaps i am looking at it the wrong way [i dont play these buy ins] and may well be losing value in some hands, i will certainly take your points on board in the future, thx for the feedback
