I really like mpethy's comments, and for the most part agree...but to say the era of stacking off light is over, is wrong.
In the last month, I've had sessions where I've won 3 buy-ins or better a few times, and in all of them, I've gotten tourists to stack off with TPTK or less for 200bbs in every single one of them.
In one hand at Aria 1/3, I was HU against a villain who had AQ against my AK. I had $650 and he had me covered.
The flop was AK6 rainbow. I bet, he raised, I called. Blank turn. I checked. He bombed the turn. Again, I called, knowing i'm shoving a half-pot-sized bet on the river with any card. the river was a J. I pushed, he called.
Insta-stack-off 200+ bb with TPGK.
Last night, I saw two players - both with over 400 bbs - get it all in on a 542 rainbow flop. One player had AA. The other had TT. 400 bbs deep.
One of these players also got it all in with another over 300 bbs deep with QJ on a Jack-high flop.
So while I certainly agree with Mpethey's thoughts on raising, I have to disagree with Venice's claim that Vegas LLHE isn't still quite fishy and quite good.
