There is a famous saying in poker: "Any two cards". This relates specifically to Texas Hold 'Em, by far the most popular variation at the moment, both on-line and in the real world.
The screengrabs below are all from hold 'em tournaments. I have but rarely played hold 'em cash games, and would not recommend it, certainly not the no limit kind. These are all low limit games, most of them freerolls, due partly to my chicken-hearted nature, partly to my belief (unlike Milton Friedman) that there is such a thing as a free lunch, and partly to what little wisdom I have. These are not all hands that I have played personally or that I was involved in. As far as can be ascertained, they are in chronological order.
September 8, 2012: All-in pre-flop. I can't remember for sure what happened but I think the guy with the 6s raised, as you would do with such a great hand, then called my all-in. The second card was scary, but the bullets held up.
The first of two screengrabs from a freeroll on October 18, 2012. This is not a good flop for kings, even slow playing, but one player kept calling small bets and on the river I made the nut flush. And didn't get paid.
The second of two screengrabs from a freeroll played October 18, 2012. Raise and flop two pair, you're probably in front, so why not whack it all in to shut out the draws? Because the other player may have a set?
The first of four hands from the 23.00 Freeroll on Party Poker and WPT Poker, played here on the latter. The no limit hold 'em tournament had a $250.00 prize pool and paid 1,100 places as usual. Here it had 9,724 runners. Aces hold up heads up at level four. I had pocket aces 4 times in this tournament, this was the third.
October 21, 2012: The very next hand, this time our hero has the kings, and they hold up against the same player.
In Hold 'Em On The Cheap, I said I was finished with no limit hold 'em sit and go's. That resolution didn't last long! Immediately below are three screengrabs from a small bounty tournament. These are a variant of head hunters, or vice versa. The small fry below had 9 runners, paid 3 places and had a buy-in of $1.00 + 27c + 15c. I finished 3rd winning $1.94 and 81c in bounties for a total of $2.71.
