3 folds, BU raises, Hero ?
fold (0 Points)
call (0 Points)
3-bet/fold (0 Points)
3-bet/push (2 Points)
Your answer 3-bet/fold (0 Points)
In this situation, you are confronted with a steal from the button. Your hand is much too strong for a fold. If you decide to just call, you put yourself into a tough spot post-flop. In case you flat-call AKs here, which hands would you 3-bet? A 3-bet should thus be standard.
3-bet/fold with AK would be really annoying in this spot as the button stealing-range is very loose, meaning you can expect 4-bets more often. If you 3-bet here, you should be willing to go broke - 3-bet/(call)push is the best choice here."
In the article is said specifically that AA and KK were the only hands to go all in with. QQ and AK were "supposed" to be folded. Is it because of the short table (only 6 players)? Thanks.
