re: Poker & $2 NLHE Full Ring: AJo light 3-bet and double barrel with AKs (40bb)
Hand 1: Preflop is very questionable... I'm usually 3betting AQo and AJs but I'll usually just flat-call with AJo in this spot. It's not horrible to 3bet here though. Once I get 4bet though, I'm snap-folding. Your only chance of winning is if the board has an Ace on it, and even then, you're going to run into AK a lot.
On the flop: this is an awful call. You're calling a shove of more than half pot with Ace high and a gutshot? Even if he is bluffing
with AK, he's still way ahead of you. I can't think of a single hand in his range that you have even close to 50% equity against. You need 35% equity for this to be a breakeven call, but you are far from that.
Hand 2: Preflop is fine, flop is fine, turn should be a check/fold. No reason to barrel when you haven't picked up any equity.
