[BluffTHIS!]

If you reraise big, and if the opponent then does not fold this leaves him:

AA: 6 ways
KK: 1 way
AKs: 2 ways
QQ/JJ/goofy: 3 ways, which is 1 way each out of 6 (goofy assumed to be 6 ways but might be more) since "usually" fold was specified.


Thus you are ahead 5 ways, tying 1 way, and behind 6 ways when he calls or moves in. And it is important that AKo is not in this mix. So overall you are going to be behind 6:5.


To me then, reraising big gives you the best read on his hand while *usually* denying him the ability to call for set value, while at the same time losing less when you will be out of position if you just call. And that calling isn't much of an option since he knows you have a big hand and yet can still bluff you on an A flop with QQ/JJ/goofy.


The real question here is how much are you destined to lose in a situation where you hold KK versus AA on the few times such situations occur, and can such losses be minimized either by a good read and folding, or by playing in a way that could allow you to steal the pot when actually behind. This is why I would actually prefer to limp reraise with KK in early position a larger percentage of the time, because it will end up costing less to fold if I read it as necessary.

So in summary, I say reraise big and be prepared to fold to a push or a called flop where an A flops or you don't spike a set.
