The BTN is an unknown player. The 9 on the turn is not the best card but nevertheless I shoved the turn as I'm beating most possible combinations there (44+ except for 99 and everything else upwards of connectors like 76+ except for JT (or T6 which is very unlikely to be in his range)). Also some fishes shove their flushdraws on boards like this. In retrospect I'm thinking I should have cbet a tad larger to protect and get most value from draws? I still think the shove on the turn is not a bad route to take against an unknown player. What do the coaches think?
