I played a few more sessions after I last wrote about this. I have ended the experiment.
It was well worth doing!
My conclusions are roughly these:
- It is possible to screw up big time preflop and still be winning
- My normal play has not played particularly well versus this type of player
One obvious point: Valuebet! Don't try to blow them off a hand by c-betting. Bluffing or semibluffing is not going to work. Why even try it? For instance, don't automatically bet your flushdraws. Don't try to "protect" when it's uncertain that you have the best hand. Respect raises on the flop, and on the turn. Don't necessarily respect river raises: These guys go to the river so often that they must steal some pots on the river. If you have a winning or marginally losing (70/3/0,9/45) guy directly to your left, then he is going to be you headache that session, not the 3 regs at the table. Don't try to read the board; they may be floating all the way to the river to take it away from you there. There are probably tens of other things.
Of course, I "knew" this before the experiment. But "knowing" in theory is not the same thing as putting something to practice. I haven't played anything since my experiment, but I hope I'll handle this particular player type with a little more respect in the future, meaning that they might just know what they are doing (after the flop).
EDIT: A clarification. The fish I was emulating was loose and very passive until the river. Thin valuebetting in the form of bet-folding on the river would have been a disaster vs me because I bluff-raised (successfully) a lot more than game theory dictates.
Anybody else tried something like this?
