By raising, as is so often said, you give yourself 2 chances to win the pot - by making the best hand or by making everyone else fold, which is fine with pretty big blinds.
Correct, but with two stacks above 25BB, I don't consider these to be "big blinds" just yet. If you are at the 200/400 a25 level, the blinds are much larger in relation to your stack.
However, upon re-analysis of the hand, raising is most likely correct here, but I still do not like the fatc that you are OOP if you are called. However, raising to try and take the pot now is a good strategy.
With the BB calling and the button raising to 2000, you have to call 1200 more to see a flop. You have to assume the BB is coming along for the ride (with half his stack invested already). There is 4515 in the pot when it comes back around to you, and once again you have to call 1200. You are getting 3.76:1 odds on your call here. This means that you are getting correct odds to call even if you are as much as a 79:21 underdog.
I have a program called PokerStove which calculates your
equity against ranges of hands...
Here is the output:
You: KhQs 30.8%
BB: (Hand range of 22+,A2s+,K9s+,Q9s+,J9s+,A2o+,K9o+) 26.9%
Button: (Hand range of 44+,ATs+,KJs+,ATo+,KJo+) 42.3%
(Computed over a possible 567,492,156 scenarios)
So, if these ranges of hands are correct for your opponents, you only need to be getting at the very worst about 7:3 odds or 2.33:1 odds to call. SInce you are getting better odds than this, I would call... and re-evaluate on the flop.
This math problem does not take into account what will happen if you miss the flop, and/or turn and river play because your opponent is not all in. However, I think I still make the call here and if your read is that he has a mid-pocket pair, you may be able to make him lay his hand down with this flop.
