Flopped boat OOP against LAG ($5/5)

[wazz]

Notes on villain: after raising pre (with a weak range!) will lead into a 3-way field with middle pair no draw on drawy board (5JQ w/ fd) and 3-barrel until the river (assuming no draw got there).
just calling sandwiched = a trap? did it with top set = nuts on drawy board

he's 34/6/2/1231. he shouldn't have any significant history with me under the account I'm using. he c-bets a very high %, so I'm not a fan of leading, though maybe I should consider it.
