BTN vs blinds: flatting vs 3betting?
I play 10nl full ring and was recently reading "modern small stakes" by Nathan Williams (blackrain79) and came across an interesting section about button vs blinds situations. I'll sometimes post a hand history on cardschat or elsewhere about how i 3bet ATs in the BB vs a BTN open from a reg, and get a lot of replies saying "ATs is a standard flat here".
However the book suggests that you shouldn't really have a flatting range vs a button open and that whenever you have a hand you want to play, you should 3bet. The reasoning the author gave was that he doesn't want to play a pot OOP without initiative, whilst 3betting regains initiative and picks up dead money when villain folds pre. He gave a similar argument for CO vs BTN, stating that button should be 3betting very wide and almost never flatting. The only time he flats is for "balance" against some of the better regs capable of 4betting a lot.
I sometimes hear people say things like "well 3betting just folds out worse hands and keeps in hands that have you beat, so flatting has more value" yet they are forgetting that flatting profitably requires you to outplay your opponent, which is hard to do without the lead in the hand especially OOP. Some micro stakes players have tried to pull this off, and end up attempting fancy plays like check/raise bluffing
to try and outplay their opponents, and end up just burning money.
So what do you guys think? Do you think flatting in the blinds is wise vs a LP open? What about in the BTN vs CO?
