[Double Down]

I think raising to 500 here is best and here is why: If you're pretty sure villain has aa or kk, then he will reraise you no matter what you do because he doesn't want any draws to hit. If you were to just call 150 and the villain bumps it up, correct play would be to push, but there is a problem with that. It looks mighty suspicious to call 150 and then reraise and the villain could put you on your set or even just 2 pair and let his big pair go.

But if you raise, he will still reraise you to see where you are at. It's better to make it 500 because then his reraise will be close to committing him. (If he min raises, it'll leave him with 1300). Now it gets a little tricky. If you think that he will call an all in if you hesitate and then push, go for it. If not, you just have to call and pray that a scare card doesn't come off.

And there are a lot of them. If you call his flop rereraise he now has you on a10, jacks, queens, possibly 2 hearts, or a hand like 10,8 hearts. There are a lot of cards that could come off on the turn or river that could kill your action. If any heart, 6,8,10,j, or queen comes off he will be scared you made your straight/flush/set. That's 25 cards. If he has kings, then add a few aces to the list of scare cards. Use good judgment and if you think you can get him to call your push on the flop go for it.
