Again your lack of knowledge about sports (betting this time) shines brightly.
You need to be creative sometimes. Stop sticking to the Stone Age and think out of the box. You can definitely create a strangle like strategy at a Vegas casino if you have half of a brain. And even if you couldn’t, I never said you could - I’ve bet as much outside of Vegas as I have at a casino, and for the former you have complete flexibility. Stick to what you know, please.
