In effect, in Kelly-betting terms, the "bet" one makes is one's buy-in when one sits down in a particular game. A Kelly-betting poker player is going to play in a game with betting limits that maximize the player's rate of growth of her bankroll.

You use the phrase "buy-in". Is there a difference in ROI / Risk of Ruin based on similar buy-ins but with different limits ? In other words, does a good player maximize bankroll growth by:

sitting down with $400 (100% of max allowed) at 2/4 NL

OR

sitting down with $400 (40% of max allowed) at 5/10 NL

I realize variance would be much higher but am using the assumption that player is adequately bankrolled.

Thanks in advance.
