$11: Check my JJ line

[Burno]

How much did he open for with QQ and KK on the other tables? If we know he opens big pairs for a smaller amount, we can discount his range accordingly.

How did he double up?

His raise suggests a good hand that wants to discourage multiway action. I think hands like 77-TT and some big suited broadways may be in his range as well, which could tip this towards a push.
