Preamble
At the time I felt that this could be a good resteal spot but I wasn't sure and did not execute.
I ran some rudimentary post game analysis and think it could've been a +1.23 M shove that I missed, which is pretty big given that's 22% of what I'm left with when I fold.
However this is based on some narrow ranges and that assumption may well be completely out and could really change the result.
Hence I'd like a second (or third…) opinion. Maybe some keen tool user (like ICMizer or SNGWiz) can play around and give me some decent information to think about?

Setup: situation, player types, image, and history
It's level 12 of the big 4.40 so about 40 mins of play until the bubble bursts (so no bubble dynamic, and chips needed). There is one sitter who just got moved to the table waiting for the button to pass, so raiser is MP1 but may not notice and hence might play more like EP.

Hero has been at table 56 hands (both opponents seen all) running 16/16/0 played 0 of 6 hands on sb and only has a steal% of 29. Looks like tight aggressive or even a tight passive player since only one hand of post flop play: called a 3b from bb after opening the button and folded to a cbet at 44bb effective. OPR looks good over 2009-2011 (>97%) but mediocre since (~63%). Over 5.3k games finish distribution is an ok looking 10/19/40/21/11. 15% ITM.

224 hands on the raiser: 28/12/2; has EP PFR of 16% (78) and MP PFR of 8% (49). Only seen raiser face a 3b 3 times two of which raiser was in EP and once on the button; he folded to two and called one (from EP) and this 3b was from the same player who is now (and was then) the bb see this hand at the bottom of this post*. Seems like a loose passive player who might be one who likes to steal a little from EP. OPR looks mediocre over 1.8k games at 69% with a good looking finish distribution of 8/18/38/26/10. 14% ITM.

86 hands on bb 35/20/6; has cold called 2 of 6 opportunities on bb and 3b 1 of 6, but have seen not seen him face anything like a raise and 15bb jam. Seems like a bad loose aggressive type though, leaning towards loose passive. OPR looks pretty solid over 3.2k games (>97% for 2011, 2012, and 2013) although his finish distribution looks pretty bad at 14/26/34/15/10 and the vast majority of his winnings come from 2 games at the $10-20 level which only accounts for 250 of the 3.2k games. 13% ITM.
