Hi guys
I was thinking about those problems quite a long time but I couldn't find a adequate solution…

How would you adapt your opening range in the follow situations (100BB effective stack, fish = loose passive player, all other positions play solid poker nothing out of line):
- We are in the CO and the BU is a fish. Should we go looser (try to isolate the fish with a raise) or should we go tighter (because the BU will flat call a ton of hands and give the blinds a good opportunity to see the flop for a better price or 3betting more to extract more value)?
- We are in the BU and in the SB is a fish. Should we increase our open-raise range (to isolate the fish) or our open-limp range (to see with more hands a flop)? And how would you adjust when the Fish is in the BB (any difference)?
- At the end a general question: If we are sitting on a table full of fishes how would you adjust our opening ranges in the different positions? My idea:
EP: tighter than my standard opening (because they will flat a ton of hands and we often have to play postflop in a multiway pot OOP with a too wide range)
MP, HJ, CO: tighter than my standard opening but adapting not so strong than in EP
BU, SB: looser (because we want to increase our chance to play IP against 1 or 2 fishes to abstract money postflop)

Thank you for any answer

Step one: seat change so you have position on the fish.

Step two: when playing LP fish, see a lot of flops as cheap as possible with a range that is just tighter than there's, then value-bet TPGK+ relentlessly, and live with the occasional weird 2p that they call three streets with, because they are also calling three streets with TPNK and that more than makes up for the occasional time you value cut yourself. If you don't have SDV, don't put more money in the pot.

Sometimes step one isn't practicable but of course is always better to have position hahaahha

they are called fish I think.
