1. you should have been thinking about your plan when you decided to call preflop instead of 4!
2. you should have definitely had a plan when you called the flop instead of raising.
3. If you called the flop and fold to a turn brick, you need to take some time away from the table and think about why you're making each play because your decisions on each street are questionable and have led you to this point.
AP - If V thinks of you as a solid TAG who made a 7x raise preflop, and V still 3! out of position to 45, and just watches you call the 3!, what range does he really put you on? Myself, I'd think you had Jacks.
yet you called the pot on the flop with a K out there, so it is much less likely you have jacks and much more likely you have a poorly played AK.
And now he shoves a brick on the turn which makes me think he puts you precisely on AK and has AA / KK and wants full value OR (much less likely) he's got something that doesn't want you to call the turn (like QQ, JJ, TT, or a smaller pair) and thinks you're good enough to fold to a shove.
And even if he has A
K
for a current chop, he has a lot more equity than you (60/40), making a call if you can put him on exactly AK about even money.
