Villain is a recreational player, not known to bluff and is very passive preflop. Mostly comes to play the tourney in the morning and will splash around in the cash games once in a while. My thought on the hand was the donk lead for near pot on the turn doesn't make a lot of sense if you have the nuts. Also the timing on the flop, given my small bet, Tx would call much faster given the odds.

Preflop for RFI I was using $15+$5 per limper, straddle pots I was using $25 + $10 per limper. What are your thoughts on this given ($300-$700) stack sizes?
