Preflop is horrible. You’re isolating a crappy hand with players who hate to fold left to act.

What’s your goal with the flop bet, 4way with middle pair + backdoors?

Convert your hand, don't post results, just because you have a pot/half pot button doesn't mean you need to use them, madlex be right in that pre is awful and the flop bet makes little sense

Don't iso-raise, don't bet the flop, don't call the raise. Apart from those mistakes, you played it perfectly.
