I have black Ax and the runout is KQJT with 2 diamonds. Villain leads turn and we can safely assume he has an Ace too.

Let's say the pot is $100 and villain leads for $50 and effective stacks are $1000.

Should we just flat here and hope for a non-diamond instead of raising because if V has diamonds then if we raise than he can reraise us and we'll be stacking off with him getting a freeroll for our whole stack while our payoff is just $50?

P.S. What happened was I popped him to $250, he went all in and I called. He had diamonds and luckily river missed him and we chopped but then I realized how stupid this was and hence this post.
