In one hand big dog has like j2s against that brazil pro i forgot his name, flop was AQbrick he has a flush draw, they both check the flop i think not too sure, but then on turn pesagno bets 2500/half pot big dog is out of position and he calls turn was also brick card i think. river was an ace and big dog sucessfully turns his missed flush draw into a bluff.

He said he is going to check fold basically all rivers, but why did he change his mind when the 2nd ace hit? i thought that card would make it more likely for pesagno to call. 

so my thoughts after thinking a little bit about this hand is after the 2nd ace hits its more likely that pesagno has air because he was most likely repping an ace or a queen, and if big dog bets its still in line with how he would play a weak ace.

I dont know where i learnt this but  sometimes when the 2nd pair card on the board hits its more likely they will call another bet but thats usually a turn card right? im not sure. Big dogs hand went against some fish thoughts i learnt somewhere else.
