There's nothing catastrophic about betting slightly more than the Kelly Criterion would call for. So, as 007 correctly suggests, if you bet a few percent more than what the KC calls for, you're going to have faster bankroll growth than if you bet, say, one-fourth the Kelly Criterion.
That said, if you consistently bet more than twice the KC, it IS catastrophic. Your bankroll will not grow at all and will in fact approach zero in the longrun. That's why NOTI's emphasis of the importance of understanding the KC is well taken, as well as his caution in betting over the KC.
I don't agree with 007 that it's a rare positive-EV player who would benefit from a better understanding of the Kelly Criterion. First of all, going broke isn't the only bad consequence of ignoring Kelly. A stagnant or barely growing bankroll is also a negative consequence. A "gut" feel for how much to bet is going to be extremely inaccurate.

You are both wrong but in two different ways:
1 - you have to accept that the KC will only help *winning* players or help you at games with an edge. Period. If you apply it to a game with negative EV you will still lose. So its really not fair to talk about gamblers that do it for "excitement". That's a misapplication of KC
2 - to say that "you can bet below KC but not above" is also misguided. You must always wager *at* the KC number. You must recall that the KC number is also designed to *optimize growth of your bankroll*. Knowing how much to wager on an edge is relatively simple calculation and/or monte-carlo simulation - that's just risk-of-ruin. But knowing how much to bet to *grow* your bankroll and get the most from any given EV, well, that's a whole other number . . . in fact, that's the KC :-)
