I would also like to add... you should play a little bit looser not tighter on the table with fish!

You should also try to isolate more. Raising with two big cards, Axs and the higher end of medium pocket pairs if its stands a chance to be against you and the fish.

When i say looser i dont mean anywhere close to the fishes calling standard... i mean just one or two notches looser then u would at a usual tight-table.

Try not to get hung up on the results of individual tables or individual sessions or the results of timeframes (weekly, monthly, etc.). Train yourself to just play winning poker and let the results take care of themself. Easy to say, difficult to do. But the truth is you just need to make the right decisions and let everything else be damned.

When I find myself playing to protect a winning session for psychological reasons I will usually just stop playing and book the win. If I am not playing +EV poker I should not be at the table.
