V is unknown, only hint was his stack size, which leaded me to think I am playing against a fishy player. I think we can make a profitable calldown here. If we think in a general 3b range from BU (maybe: 66+, ATs+, A5s-A2s, KTs+, QTs+, JTs, T9s, 98s, 87s, 76s, 65s, AQo+), after his flop half pot bet IP, we can exclude some hands. IMO, he will usually checkback his stronger PP-s, like 99-JJ, his Qx or Kx hands and bet with straight draws, airs and strong hands. OTT I give him this range: QQ+,ATs+,KQs,JTs,T9s,AKo, he will usually give up his airs. OTR, there is no significant change in his range. We are blocking KQ, AK, AA, QQ from his value range, but with our Ace also blocking his AJ, AT. But all in all, we are probably talking about a fish, who just sees his two cards, does not give a... anything to ranges, just clicking halfpothalfpotpot. So what do you think about this spot? If my range is right, OTR we have 38% against QQ+,ATs+,KQs,JTs,AKo w 27% potodds.
