ok sso here's my problem. as you can see the BB is a superduper idiot min 3 betting into 3 people vs an utg open lol. anyway , when i made my hand on the turn the RR was obvious , however when the river paired i was a little bit worried about the guy who had relative position on me after i bet . so on the river i was thinking to bet to extraxt value from the donk in BB obv ( his range was very likely to be a horribly played overpair) . so when the other decent reg called my RR on turn as well , and the board pairing i was thinking to make a betsize which would both allow me to extract value and give me some FE vs the reg. Or am i being a horrible nit here?
