in scenario 1, where I have KQ and I know he has a pair JJ or lower, I flat call his raise preflop. If an ace, king, or queen comes, I go all-in.

in scenario 2, where I have 99 and I put him on two broadway cards, I push it all-in. It's a gamble, yes, but it's winner take all, and you need to get some chips. So there's little reason to play it safe at this point. There are too many flops that will miss him, but still force me to fold anyway. Therefore I'd rather take the indecision out of the hand and push it in now.
