$5/10 NL at B&M Casino. All have about $1500.

Hero is new to table. Dealt A [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img] UTG.
5 Players see flop of 4 [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/club.gif[/img].

All check to Villain Button who bets 40. Hero is only caller.

Turn: Q [img]/images/graemlins/club.gif[/img]. Hero checks. Villain bets 40. Hero looks at cards, wanting to give impression he's checking to see if he has a club, then raises to 100. wanting to represent bare A [img]/images/graemlins/club.gif[/img]. Villain reraises 200 more. (Pot size $530)

QUESTION 1: CALL, FOLD, RAISE MINI, OR RAISE BIG? WHY?

Hero sees str8 flush is possible, but thinks it's more likely Villain has K high flush or (less likely) a straight or (less likely) trips. Hero decides to call, representing bare A [img]/images/graemlins/club.gif[/img] draw, and also figuring to save money if str8 flush is out there. He also hopes not raising will give impression he does not have Ace high flush and will get another bet from Villain.

River: 2 [img]/images/graemlins/diamond.gif[/img]. Hero checks (same logic as above). Villain goes all-in for $800. Pot size $1530. You have him covered.

QUESTION 2: CALL or FOLD? WHY?

Hero asks Villain if Villain will show if Hero folds. Villain says yes.
