Player A has £40. Player B has £40.

The pot contains £40 and Player's A and B are the only two players in the hand.

Player A has Ah2h. The flop is 7h8h9s. Player A acts first.

Let's just say for argument's sake that if another heart comes, then Player A wins the hand. And also, that if Player A hits top pair, trips, 2 pair he still looses the hand - Player A needs to hit his flush to win the hand and nothing else.

How could Player A play this hand?

Would you say that Player A moving allin is an acceptable play? If Player A does move allin he'll be getting 2 to 1 on his money and since Player A has a 35% chance of hitting the flush - it's a good bet. Also, Player A has folding equity. He could win the hand straight away if Player B folds.

Is this an acceptable way to play the hand?

What do you think the optimal way of playing this hand is? (We don't know anything about our opponent and this is the only hand we will ever play against him)
