First of all, first post, Hi everyone.

Secondly im sorry if it isnt in the right place but it seemed the best place to post these q's.

1: Can you check on river right round the table or does there have to be some sort of betting. (I think no you can all check then show cards)

2: If I am heads up and I raise and they call and we are on the river as he called me do I show first or as he called does he show first? (I think as I am called I show first)

3: The first 2 rounds of betting the minimum is equal to the small blind and the last 2 rounds of betting must be equal or greater than the big blind?

Thanks in advance.

Aaron.
