Sometimes I play a hand and during the hand I have good reasons for making the decision I make on each street but after the hand I look back and it doesn't feel right, like I must have made a mistake somewhere but I can't always see where.

Below is an example of one of these hands. Sorry I don't have a HH, it was played on a site where HUDs dont work. It was played at £1.5/3 which i guess is about $2.5/5.

HU against a reg, main reads are that 1) he doesn't like to fold much, but this is mainly when i have initiative and am barrelling 2) he bets merged with a lot of hands that he just doesnt want to check, so that when he does check he is very weak

At this point he was tilted and 3 betting 40-50% of hands.

Effective stacks 300

I open button to 6 with K4cc, he 3bets BB to 24, I flat

Flop ATTcds

He cbets 60% pot, I call. I figure I'm ahead of his range and im very protected on this board so he can't barrel relentlessly.

Turn 8d

He bets 60% pot again and I call. Here I feel like most players check Ax but barrel Tx and draws. On this turn he picks up a lot of straight and flush draws so my K high is good. I'm also protected on rivers with a ton of Ax and Tx that I play this way 100% of the time. This opponent is more likely to just bet like A2 on the turn which is bad for me, but he is still in a very difficult spot on rivers

River 2d

He checks. At this point I have so few bluffs and have all Tx, a ton of Axd and the broadway diamond combos that I feel like I have to shove my hand. He may play AJ this way and then call to protect his range but my range is so strong and I am at the bottom of it with K4cc so I have to shove.

So I end up getting to the river with K high with no previous draw and shove my stack in, which in hindsight sounds ridiculous, but in the hand I feel like I had good reasons for each street. Thoughts?
