As played on the turn put him all in as the effective stack is $4.85 with a pot of $6.55.

Don't worry about folding out worse hands with a shove vs this guy - the bottom of his range (6x,v weak Tx,air) is unlikely to pay you off whatever you do and by betting this way his sets can draw to a full house.

We get so much value from the rest of his range {33,66,TT,worse flushes, good Tx including T6} that shoving is the most +EV.
