I don't think there's anything wrong with the RNG. The boards don't seem to be any different than those on the cash sites I play on, and have played on. However because of the way players play on this site, if you want to be a winning player here you need to modify your style of play somewhat to take that into consideration. Tactics that work fine against regs who have some idea of what the game is all about, are often nothing but a losing proposition on BUP. Obviously still use your game knowledge to play smart, just adjust.
Understand that the player who generally limps/checks/min bets may have actually made trip kings on the river, even though they only min bet. So don't raise with your two pair, and get crushed. I actually played in that hand and lost
, but believe me I now know to lookout for that type of behavior from that player. Or the pre-flop raiser who bet 8 BB's is holding 8,2o, and then, yes as sometimes does happen, he WILL crack your A,A, when he hits his two pair.
Use player tags, take detailed notes, and realize that players here will play hands that no reg would ever be caught dead playing, and accept ahead of time that when you 3 bet, the whole table who limped will often call you with nothing more than a low pair, A + rag, two suited cards, or nothing. Everyone here is a either a super fish or play like they are. I've played on other free sites like NLOP and Pure Play, and am a regular on Poker Stars using free chips (only way US players can play), but I think BUP players are the worst.
I would say at least 75% of the BUP players are total fish who've learned how to play badly by watching other fish, and have no clue how to even spell poker, much less any knowledge of strategy. Bad play and high aggression is the name of the game, because hey, free chips, so if they lose,so what - it didn't cost them anything to begin with, and you can't win much anyway.
Since you mentioned your WSOP cash (well done!), I'm thinking maybe you haven't had much experience playing online. Sorry, but deal with it, get over it, or go play somewhere else. Nothing gets me steamed worse than the guy who's always complaining how he can never win because the site's RNG is faulty/rigged.
