In games with a maximum pay out you should never bet so much that the maximum winning would be affected by the maximum. For example if the maximum pay out is $2000 and the biggest win pays 100:1 then you shouldn’t bet more than $20. Assuming the royal flush there pays 100-1, you shouldn't bet more than $30. As long as you stay under these limits the odds have not changed. The version where you can switch a card is called Oasis Poker.
