This is one of the rare occasions where I get caught busy 4-tabling and working in the background and I paid almost $400 for it. I couldn't have played this hand worse if I tried, but I think some people would get stacked here. First mistake was checking the flop, I understand that. UTG+1 is fairly LAG, not sure too much about MP3.
Please don't comment on preflop or checking flop but focus more on after MP3 raises to $45. I think the question isn't DO you fold, but more WHEN do you fold this?
