200bb effektive stacks or more. So hero is on the button and whenever he opens up villain 3-bets. And villain almost always tries to push hero off the pot post-flop. If hero 4-bets villain calls and does something crazy on the flop. If hero limps villain plays ok poker. So what hands do you open up?
And I believe I have had these kind of players yesterday and today. Some results (nl 100): me 100 villain 300 to me 1800 villain 0, me 400 villain 100 to me 100 villain 1100 to me 1200 villain 0.
