I have and Ace and a high value card pre flop and am playing at a table with eight players, and I want to know what the probability is of an Ace or the high value card coming up on the flop.

The reason being I lost a game today when I called a leaders all in, this has happened to me twice today, but I learnt from my last mistake I just had 8-8's and got beat, and thanks to the replies to my other post I've learnt that this is like tossing a coin.

But this time though I had Ace King, and the chip leader still beat me with 9-9. By this time there was only us two left in the hand everyone else had folded.

Thanks
