.15/.30 deep line check?

[RiverHebrew2]

Uh, interesting spot; I should have shoved the flop but this guy wuz overaggro and I thought I could get a lot of $ out of him on the turn since he would always fire a 2nd barrel no matter what; i checked behind when flush hit; after K hit he potted river and I had to fold. Ne thoughts? Sry no converter; wuts a good FTP converter..?
