#2 split evenly
#1 go ahead and call because why the hell not. 30-40% to straight up win a sit-n-go, i'll take it. may be smarter to fold, and get a guaranteed second, but its just one sit-n-go, i'll take first please.
#3 fold. here, you're probably looking at like 5% to win, automatic second is definitely the way to go.
