The Big 16.50, final table, already down to 3handed I am shortest stack with 16BBs. To my right is a total aggrodonk, tagged as 'noob' (I don't stream, so I can use the non-PC tags ;) ) who ran hotter than hell winning the most incredible preflop all-ins open shoving for 30bbs with A3o MP earlier at the FT, etc. He's the chip leader and shoves into the both of us around 60-70% of the time, but in this particular hand he folded pre. To my left is a guy who definitely played on the nitty side with 17/14/3b-8 over 248 hand sample.

Problem is that I'm now unsure if that shove into the nit is correct with my 74s.
1st question: is this chart reliable? (I shoved based on it) - mtt push/fold chart
2nd question: are there ICM implications (if so, how important) when I'm shortest stack, everyone folded to me and I'm on the SB?
3rd question: is this shove correct?
