interesting indeed...
Follow on question, what would you have done if he had stuck his chips in on the river?
the turn call was made mostly to let ur oppo bluff the river, so ida snap called. There aren't many made hands that fold on the turn to a raise that will suddenly push the river (apart from AQ) for value, so your equity against his made-hand-range will mostly remain unaltered if you push the turn or check/call the river, but calling turn and checking river introduces whiffed draws/3 barrel bluffs into the equation, and as wellchief alluded to earlier, your hand is a good bluff catcher that wont fold out many better hands , so widen the range and snap off some bluffs.
