Say you have K8 in early position. Normally this is an automatic fold, no regrets. Flop comes out KK8 and obviously you are going to stack off any AK or KQ. Just a little feeling that the next flop is going to smack you in the face.
It would be hard for me to fold AA preflop. I can see a situation in which I would. I am in the BB and 3 people at my table have more chips than me, and there are 5 all ins prelfop. Only 1 of them is a short stack. Against 5 hands, AA isn't looking that good.
However, I was in a cash tournament $40 buy in several years ago. I was still new to poker and admit, i played abc poker. I'm facing a bet and a call in front of me. The bet was 4x. I was in middle position with AQ of spades. Normally, i would just snap call without giving it a 2nd thought. This particular time my instinct told me to get out the way. After about 40 seconds, i folded. Flop comes out A55 on the flop. It was 3 bet on the flop. A spade falls on the turn, is was 3 bet all in. Once the hands were flipped over it was Aces full vs quad 5s. Aces full was drawing dead since i folded the case ace.
Sometimes this gut feeling works both ways. If it were any specific read I have, I would probably go with it. Betting patterns, splashing the pot, speed of the call. I am getting better at tells
but I have always been a believe of what are his chips trying to say
