I am not crazy about that starting hand and if I'm going to play it at all I'll usually limp in with it in late position.
Consider also that even if you catch your king on the flop and have the current nuts as you did there you may be an underdog <font class="small">Code:</font><hr /><pre>

However, change a couple of your cards to give you nut flush and low draws and it makes a big difference

On the turn, of course, it might be the set of kings that are an even bigger underdog than what I displayed in the first code example, drawing to the full house or quads.

Like I said, I play this type hand very carefully because I tend to either win smallish pots or lose large ones. When I fall in love with the top set and have no redraws to a low, straight, or flush in addition to the obvious FH or quad draw I have ended up regretting it. Just my $.02.
