On PokerStars bots have been received

If you play poker online which is risk to face swindlers.

The pokernoe community in the last exposed deceits of exclusive users and scandals with plural registration of login accounts, and now players PokerStars has learnt bots.

All beginning last Tuesday when the participant under any “malloc” at a forum Two Plus Two has expressed doubts concerning three players. Besides similarity in their style of game, he also has noticed that they played the same levels, the lowered limits after the almost same quantity of distributions during the short period of time, and so on a circle. The first participants of a forum have met the statement with the indifference, some have tried to find other explanations to common features in game, others have assumed at once that it is bots.

The statistics on them, presumably, to bots has been found on a site PokerTableRatings.com (PTR) where the data on millions players online gathers, and by means of a tooling users as their contenders play can see. PTR in May has learnt an interval in system of safety network Cereus Network. On 16th of July the participant of forum Two Plus Two under any, "Gugel" has placed the information, has found it on PTR which has ostensibly opened final communication between given to three login account.


But after this very day there was an official information. Management PTR has published the report with «plural certificates» that ten accounts on PokerStars actually were bots, i.e. coped the computer program. Taking a post malloc’а for a starting point, employees PTR have analysed the data and have found out that at 10 login accounts very similar statistics, they changed rates in same or nearly so the same time, and at them the characteristic obvious line of rates was traced.

Having begun with the game statistics, PTR have prepared the schedule with 28 statistics on each player, including VP$IP (percent of distributions on pre-flop in which the player puts up money in bank), рейз on pre-flop and percent of 3-3-rates on different positions behind a table and as a whole, and also percent «seen flop» and aggression indicators on флопе. You can come on site PTR and own eyes to see the given schedule, but as employees PTR have declared, «this statistics is too similar to be usual accident».

PTR have gone further and, using for comparison six defined the statistican, have calculated Euclidean distance for each player in games of $0.25 / $0.50 No-Limit Hold’em which this year have played not less than 100 000 distributions. Than it is less Euclidean distance, style of game between two players is especially similar. Taking one of suspected bots for an initial indicator, they have found out that the greatest distance between any bots made 2,39 whereas the least distance between the usual player and an initial bot equaled 32,94. According to PTR, it proves that ten suspects "are almost identical".

PTR also have confirmed supervision malloc’а concerning a similar line of change of rates. They began with $1 / $2 No-Limit Hold’em, then decreased to $0.50 / $1 approximately at the same time, then simultaneously passed to $0.25 / $0.50. Suspicious and strange that though players won also seemed to many participants Two Plus Two, they continued to reduce rates.

At last experts PTR have found out that at ten login accounts the certain line of rates is obviously traced. They have told the following: «When they are on a position big блайнда in sweat without rise (where participants only did the minimum rates), and on flop the contender declares the check, they either go va-bank or bluff, staking. If in reply to the rate of a bot the player make call or does rise, the bot always dumps maps, reacting to aggression».

According to PTR, bots on PokerStars are following accounts: 7emenov, bakabar, crazier, mvra, nakseon, kozzin, demidou, koldan, Daergy and feidmanis.

Many on Two Plus Two have been upset by that PokerStars has not distinguished bots to PTR, and all of them still played a site after PTR has published the report. On July, 17th, every other day after promulgation of report PTR, representative PokerStars has explained on Two Plus Two that they have made own investigation under the given login accounts and have come to the same conclusions. However accounts have blocked only in second half of day as they tracked down other similar login accounts and did not want them to frighten off, having closed access to already established bots before the investigation termination. By the end of day employees PokerStars have considered that other bots are not present, besides distinguished ten, and a site have cleared of swindlers.
