I play like 2 to 3 times a week, its basically the same as home games the only difference is you might pick up on your friends habits/betting patterns etc the casino is usually complete strangers
There's a game called 2-4 Holdem and its relatively cheap to sit down at that table ($30-$40 is usually the buy in) there's no going all in but its something to get you use to the playing field
1/2 No Limit is what I play, I only really bring $100 with me... I'm more on the winning side than the losing side but if I lose its only $100 it doesn't make me or break me so
I'd love to play 5/10 No limit but I don't have 2k to throw around easily haha
