Yeah some probably do. There's some posts around the net of people claming they're coding bots and letting them run on different sites. Although I can assure you I can also recognize set-ups where I can suck you out with full houses when you go all in on the river and may decide to call you at different times. You don't need to be a bot to do that. You can be a donkey or a regular who has seen so many set-ups that you just get that feeling to pull the trigger. If you got action flops, then generally, if you got the best hand on the flop, you probably won't still have it by the river in a multi-way pot. If I'm on a gutshot straight and I have pot
odds or looking to take a risk to chip up for a tournament, I'll call all-ins and raises like that but after all that's what you should want with top pair. For people like me to take those chances and try to knock you out, because more often than not you will win, but sometimes I do, and when I do, I usually get paid. It's situational.
If I raise with a very strong hand for example, and you smooth call me, and I miss the flop, but I put you on a weaker draw hand, it looks very dangerous for me, but I am sitting on AK suited hearts and you have a weaker hand, like AQ and hit 2 pairs, well I still remember my preflop odds and those need all 5 cards to work out. In this situation I was a huge favorite preflop, and that includes hitting boats on the river when a weaker hand has top pair or in this case 2 pairs on the flop? So could this be case where the turn and river bring a J and a 10 or 2 or a KK. Let's find out. I pull the trigger in these cases sometimes.
Remember winning odds doesn't mean AA is an 80% when people only have 1 pair it also includes situations where someone has straights by the turn or on the flop, and AA ends up quading or pulling off higher straights, or hitting that one outer flush. That's why you should generally try to play it to the river to get the full 80% benefit. You will more often than not be wrong, folding a hand like AA even if it seems you are beat on the flop or even the turn. And this concept applies to many other hands.
