Interesting hand against Nam Lee in Shooting Stars

[SeriousStudent]

Nam looks almost exactly like Tuan.

18 left. Next increase in the money is with 12 left. I have about 140k with an average stack of a little less than 300K. I don't consider myself as much of an expert, certainly compared to many of the posters on this board, but my strategy for better or worse was:

Play my normal game except, as this tournament has such a high fraction of named pros, and there is at least one on each table, avoid pots with the pros, but every few hours when

One Pro has entered the pot, preferably from EP
I'm in position on or near button
I have a stack of 25 or more BBs and the Pro covers me
I have a speculative hand that the pro would not expect me to call with
No aggressive players in the blinds

to go ahead and smooth call.

This was working extremely well for me and I won some big pots this way when I hit the flop, so I decided to employ the strategy again the next time I had an opportunity.

With blinds/antes 2500/5000/500 ,6 handed, Nam raised to 15K in the cut off. He had 350K and was raising relatively frequently pre flop but with no hands shown down, so I put him on a range of Ace any, any pair, and any two high cards. I looked down to find KhTh and smooth called.

Blinds folded.

Flop Ah8h3d, pot 40,500.

Nam checks.

I have 125k left.

My move?
