hand vs durrrr, top pair deep HU

[KRANTZ]

We've been 3-tabling for about 1.5 hours. He shifts in and out of different modes - 3-betting and 4-betting incessantly, to calling and leading, double, triple bets every time. He's in reraise way light mode right now.

Some history: he seems to "value-bluff" a lot in big pots. Meaning making what appears to be a two-way bet in which a better hand might fold and a worse hand might call. Two examples:

So here's the hand - those of you who have seen results, please try not to be too results oriented. I thought it was a very tough decision - turn put up some draws so that widens his range. Gaucho was watching most of the match so maybe he can comment on anything I've left out.
