First off, you'll get more replies if you use a hand converter and include the hand within the post. One, people don't like to visit another site to view the hand, and two, the site you used does not total the pot on each street.

You made a monster, but none of your opponents have much of anything. It's unfortunate, but it happens some times. Generally, you'll get more action if an A or K comes as that is more likely to pair someone's hole card.

In any case, the board is pretty scary by the turn with the straight and flush possibilities. I'd bet around 1/2 the pot and hope to get called by a draw or top pair.

On the river, once the 8 comes, might as well push and hope to get called by a 9, T9, or two diamonds. The fact that no one bet the river means there is a good chance that no one even has a straight, in which case even a small bet won't get called.

In general, it's better to make a big bet (say $1000) and get called only 30% than make a tiny bet (say $200) and get called 100% of the time. This is especially true when betting the river (the river is only a value-betting street since there are no more cards to come that will improve either hand).
