This is what concerned me way back when. Also, while MP3 can't seriously consider overcalling, I think perhaps you are being a bit dismissive about the fact that after MP1 called MP3 didn't really put a lot of thought into the call. I am not convinced that if MP1 folds that you get past MP3 a very high % of the time.

You pretty much said it yourself though. Def not the worst play you'll ever make, but also prob better here to drop 150 and wait for a better spot.
