an unknown 3 bet and your calling with 99?? save money and fold preflop. On the flop, I really do not like your check and call strategy, it is absolutely vital, that you prevent the LMPplayer from pealing this flop with his possible two overcards to your 99's, so this is a must checkraise. Given the way you played it, I like your turn line, and I like your river check, as long as youre calling. I realize that if you check this river after you showed so much strength on the turn, and your opponent bets, that you are gonna feel retarded calling, but you will be getting 11-1, against an unknown, who may be making a desperate river bluff with AK or betting some weird hand like 55, you simply have to call. I know youre probably thinking that how can AK or a hand like 55 call your turn checkraise, so I admit that all you can beat on this river is a hand that makes no sense at all, but getting 11-1 against an unknown I think you should call.
