0) OR from Button seems relatively straightforward. This hand has many ways to connect after the flop, and given that he's appeared weak-tight so far, you can count on a steal quite often.

1) Most likely an Ace with another overcard but I wouldn't rule out the possibility of a medium pocket pair or diamond draw, or just two overcards without an Ace.

2) This is a tough one for me because I think an Ace won't fold this turn. A mid PP or diamond draw definitely won't, so the only hand that would fold is a non-Ace high card hand. I think I'll check behind.

3) 5s are obvious. The 6s and 7s are possibilities, as is a non-Ace face card.

4) Bet a non-Ace, non-diamond.
