Thanks for the nice words...
These were at a casino in Iowa, send me a message if you would like to know exactly which one.
I like to play for big wins, unless the paytables suck or I am just after free drinks.
So to answer your question playing that much would be normal as part of my fewer hands, but larger bets strategy. Often I will just pop in for 20 or 30 minutes and make a dozen or so bets like that one.
That being said I wouldn't drop $50 a hand on a single line game. In 50 play, even if you get dealt 5 duds, on the re-deal you are going to get at least some of your money back. Not true with single line, although I realize the long term return is the same.
