Just as God gives you a guardian angel, so they also give you a bot at the poker table. How do you realize that it is a bot? Well as soon as you make an opening bet he makes you 3 Bet, that has happened to me lately at the poker table where I was playing and I realized that the player, who is a bot because when I did not enter to play in the hands He does not play neither, he does not get involved in any bet, as soon as I entered, I open it, he returns with the same thing, I write to him, I launch rockets, paper... he does not respond or react, so I noticed them.
Perhaps he was just isolating you? Maybe he felt he identified something he could take advantage of? IF you do think it's a bot, why not start 4-betting light... or tighten up your opening ranges?
A few years ago on
partypoker, I'd often come up against BOTS and they'd be playing at micro/low stakes (cash game). How did I know they were bots.... good question. I suspected they were as the playing style of a few of them was very Very similar (Maybe it was a multi-accounter? ... maybe they were just playing similarly?). At first I found it a bit frustrating... they were super aggro. Then after awhile I looked forward to seeing them.
There'd be many names joining the player pool (15 - to - 20?).... & they'd all seem to be solid, AGGRO, players. Then they'd all disappear... around the same time.
Then I'd notice another dozen or more players all joining at the same time, all of them seeming to be good players. Also they would all have zero tournament play (or maybe just a couple games, played at very low limit).
Was it just a coincidence that a handful of players would all leave the player pool... and then a couple days later another bunch of players joins the player pool, all names I hadn't recognized (I keep diligent notes).. & it'd be the same for them... all playing solid, with an especially aggro preflop strategy, often a more predictable postflop play & with next to zero MTT's played... and if 1 or 2 played, they'd be at micro games and were new accounts.
Maybe it was a promotion in some part of the world? Maybe it was a bunch of players from Pokerstars deciding to join up at Partypoker (perhaps they joined around the same time due to a promo in their region... or some marketing/advertising campaign. Either way, I was suspicious.
Around that time (or shortly after) I received a refund to my account from Partypoker (a very small amount), from money compensated from Bots that were playing in the games I was in. After that, they disappeared from the site & I no longer saw what had seemed like small groups of players joining to the site (hey it could've been one or two guys, each with 10 bots... < probably much more likely than 20 separate humans each with 1 bot)
I haven't noticed it since then (or at least not recently). But because of this, I do prefer a site to allow tracking software (PT4, HEM). When you see the numbers right in your face, and you can compare with others in the player pool, it would/could help to identify them.
tldr:
I know I have encountered some Bots in micro stakes cash games... I've even received a very small refund. I don't think there's any in the games I play today.
In the games I play in I'd estimate that 2/3 of the players don't have their chat displayed. In most of the Z00M, FastForward, Rush&Cash, tables, a large portion of the player pool is 4-tabling those games... they don't have much time to chat even if they wanted to (trust me, I know... because I chat on occasionally on those tables LOL)
