I am fairly new to the game (about 1 month in) but have been playing a ton recently. I would love for some input on a specific hand that came down last night and any advice for how to avoid the thought traps which made me make the wrong action in that scenario. I know I am often an overly conservative player.
Last hand of the night in a $3/$5 holdem game against medium aggressive players, or at least players who are way more aggressive than I have been playing that night. I get pocket fives and someone before me makes a $20 bet which is called by 2 other players and myself. Flop is 5, 10, Q so I have three fives at this point and can be fairly certain I have the best hand but unfortunately I'm in the earliest position. I bet $50 which gets one fold, one call, then the guy in the latest position raises to $185. Over the night, he has made some bluffs but often has had it when he makes a bet like this. At this point I think he probably has 2 pair which I still have beat. I think forever then call, and the other guy does as well.
A random 2 comes down on the turn, I check expecting a bet from one of them but it is checks all around. Then the river is a 10. On board is 5, Q, 10, 2, 10 and I'm holding a full house 5,5,5,10,10. There aren't flush possibilities. At this point I am very afraid he has Q, 10 in hand (or Q,Q/10,10/Q,5/10,5 but less likely) based on his bet on the flop and that he will have a better full house (or quads). I check, the next guy checks, and the villain in position bets $450. I think about it for a long time but end up folding as does the other guy and the $450 takes it. Turns out he had KQ and only had 2 pair: QQ+1010, the other guy was going for a straight draw he missed and had nothing.
I really kicked myself because my decision was basically should I risk $450 for a shot at ~$1100 knowing I had a boat and there were only a few unlikely outs that he had which could make him win that hand. More experienced players told me after the hand that I should have at least called and maybe raised -- it was really my risk adversity which punished me there.
What would you have done and why? How can I avoid this type of situation in the future? From an odds perspective how could I have quickly estimated my equity was better and from a psychology perspective how should I have thought about it? Thanks in advance!
