Semi-Bluff on a Dry Board: $3/$6

[stigmata]

Pretty interesting and imaginative line, IMO. I think it is fine, given that:

1) His previous raises versus donk-bets appeared to be of the type that are trying to get weak hands to fold.
2) You think he knows nothing about you, and you could well be a donk.

Given this, which appears to be this case, he is raising your flop donk with a wide range of hands, possibly any 2 cards. I think you have a ton of FE and your 3-bet should be profitable.
