Check turn 100% of the time here.
why?
I'm perplexed too

Me too. We've got the nuts and the board is giving plenty to draw to. Why give it away for free?
Level maybe??
Maybe so you don't inflate the pot too much as
there are tonnes of draws out there and you are not that bigga favourite...it would also give a legitimate hand that you are beating (other set) a chance to bet into you on a blank turn?
just thinking obv..not actually agreeing with it but train of thought would be good here.

I've made it as bad as possible and we're still hardly a big dog.
If we check the turn and one of these draws completes are we just passing when he bets the river? Perhaps the idea is to minimise the amount we could lose?
Are we checking behind on a river that completes any draw? There's only the black or green 8/9 and the other A that are 100% safe cards so we're unlikely to maintain the nuts. I would've thought this was all the more reason to bet unless we're only ever playing the stone cold nuts no matter what.
I really can't understand why we would ever give our oppo a free card here. Seems incredibly negative thinking.
