Open shoving at 3000 starting stacks, about 115 bb deep, with blinds 10/20, with hands like even AK suited seems semi fishy, and either picks you up 55 chips or gets you called by better, and only about 13% to 27% called by worse.
Even if I check call, villain probably bets big, and I still rightly call or go all in, and end up with same result.
Also didnt have a back door draw, I had a super good combo Nut Flush draw and Nut broadway straight draw. At worst I about 50% coinflip, at average to best I about 70% to win.
Also cbetting very small, 150, shouldnt lead to how the hand played out, and most of the time doesnt play out that way, no matter how good they hit flop. The way it played out after my SMALL cbet, only happens about 2% to 4% to 6% of time, no matter how good they hit flop. If anything, players that hit that good, slowplay, or bet smaller, most to almost all of time, with the couple, few that do bet double pot, etc, either have top pair top kicker, mid pair, semi bluffing, overvaluing their hand, value owning themselves, etc.
Sometimes I do check, call in that situation. A solver says that supposed to do a mix of check calling, and cbetting small to mid size in that situation. If check call whenever in that kind of hand, situation, your going to be very predictable, exploitable, etc.
