NL Ring is free money to good players. As long as the betting is "normal" TPTK is probably the best hand, but once the betting gets hot you need the top flush, sneaky trips or the happy end of that straight. I almost never call huge bets or raises with the "obvious" hand, and I sure as hell won't do it with "obvious hand bad kicker".

The above isn't absolute and you'll lay down the best every once in a while, but you will get paid with the nutz, and that makes up for the couple little hands you might have marginally won.
