Get serious about measuring your performance: Sharpe Ratio

I think making adjustment to your play to lower std costs too much.

Also instances when you are in "marginally +EV situation with high variance" are very rare and wont help you lower std by much.

Think more in terms of game selection, general strategy, and where on the ladder of limits you decide to play as things you might adjust in order to maximize both your winrate and Sharpe ratio.

For example, if you rely on poker for your income, and have the following win rates at 3/6 and 5/10,

3/6: 8BB/100 +- 35BB/100
5/10: 6BB/100 +- 60BB/100

its not obvious which game you should be playing, even though your hourly rate at 5/10 is about 25% greater.

The same sort of argument could be made for LAG vs TAG styles, general 3betting ranges, etc. If LAG is just as profitable as TAG, but can lower your STD, then you should open up and play LAG.

All I'm saying is if we think about trying to maximize not just winrate but Sharpe as well, it might make our lives easier.
