Why do we ever want him to fold on the turn? If you can bet (or bet a bit more) to get more value.. then by all means do it.
I don't particularly like the 'small' turn bet because I think it looks a bit suspect. I'd either bet a bit more (600'ish') 'or' check back turn hoping to get more value on river.
it's just unfortunate that villain hits the miracle card obv.
(considering altering our play based on this, is results-oriented thinking imo. You've got a monster.. get the most value for it whatever way you see possible).
Preflop, I probably just fold. If stacks of players yet to act were a bit deeper I'd be more likely opening with a raise to ~500. Here I wouldn't though as I'm pricing myself in vs. LP stacks that should often be shoving. (< obviously also depends upon player reads though)
