smart or stupid? bluffing tight player (180 4.40 PS)

[r987r]

Reads on the guy were that he played very tight. I was playing semi tight also. Previous hands that he raised, he raised to 800 and 600 so I thought he probably didnt have much and I could try to make a move. First time I reraised whole tourney I think also. He has been with me for a while since 50/100 blinds.
