Tournament is a $40 + $20 5k guarantee with 20 min levels.

We are at final table with a little less than 10 bigs. 8 remain and we are guaranteed $175 if we bust out now but we are about 6th in chips.

So, competent player who I have history with from the table prior is seated to my right and is utg + 1. It folds to him and he has slightly more chips than me but our stacks are more or less the same. He open jams and I can put him on anything 66+ j10+, he could even shove 55 here. He’s open jammed the last three hands too.

I’ve seen him rejam 56s when he was chip lead at previous table.

We look down at A10off. In my mind it was a $600 coin flip.

Hero?

If we double up here we would be third in chips and get about a $600 pay jump and have a shot at first $1500 or second around $1000.

Thanks for any help, I’m really unsure about this spot. I know I can just run my equity against his range preflop but I have no idea about ICM implications here. Plus, this was more of a live read/feels play any criticism is appreciated.
