Managing a bankroll. Let's say you have a player in a tennis tournament who you think will do well and will be overpriced/undervalued by the market. It is a tennis tournament and you back him outright e/w. Then you have the individual matches too. Let's say you have a notional bankroll of 100 points allocated to be tennis in this tournament. How much of it do you put on your man outright, how much do you put on the individual matches? Do you save some for other matches for things you spot.
If you are backing a player outright for the tourney and then also steaming in backing him for individual matches, if you are allocating alot of your points for doing this aren't you opening yourself up to a lot of variance? Or is it actually less variance to back a bit outright and then on the individual matches, because he may well win one or two matches, so you will win all those bets and not lose it all compared to if you just bet 50 points e/w on your player and he doesn't make the final.
