We are first to act and the book recommends checkraising here to try to maximize the value of our big draw.
In the book, hero has 12 outs, in my hand, I have about 9.5.
In the book, there are 5 players. In my hand, there were 6 players.
In the book, we don't know whether or not UTG bet and we don't know how many people called when it came time for hero to decide to call or raise (folding was completely totally and in all other ways out of the question). In my hand, when the action got back to us we knew it was a 4-way pot.
I would argue that in the book, there was a slightly higher chance somebody already had top pair due to the K on the board than in my hand where the top card was an 8, not just because people are more likely to play Ks than 8s in general, but because in the book, a UTG raise is probably assumed to be a tighter range than this specific villain's BB raising range in my game. I'm not sure how much that matters though, because we're extremely unlikely to win by spiking a pair in either hand.
I'm having trouble feeling like my flop checkraise in that hand is more than a small mistake at worst. It may seem like I've made up my mind but I promise I am open to further discussion if there is any.
