betting according to your advantages. For example, you play at a 0.5% mius off-the-top game. You have about 1% advantage on TC 3, one Kelly is betting 1% of your "total" banroll which has a risk of ruin of about 13%. 2 Kelly you win faster but take higher risk, half Kelly is better but you make less if play against small bankroll. I travelled playing over 50 countries so far. My 'hit and run" is on world-wide travelling basis...: )
