Omaha Hi Hand Evaluator

Question

Hi, currently im trying to port Keith Rule's Texas Holdem Hand Evaluator to Omaha Hi:

• Texas Holdem Evaluator and Analysis
• More Analysis Part1
• More Analysis Part 2

After thinking more about the algorithm, I found a solution which gives me the right percentages for the hands and everyhting is fine..

But it's really really slow. How can I speed things up?

As the only thing I do right now is to lookup a normal five card hands, a LUT might be right for me. Anyone integratet one before?

static void Main(string[] args)
    {
        long count = 0;
        double player1win = 0.0, player2win=0.0;
        ulong player1 = Hand.ParseHand("Ad Kd As Ks");
        ulong player2 = Hand.ParseHand("Th 5c 2c 7d");
        foreach (ulong board in Hand.Hands(0, player1 | player2, 5))
        {
            uint maxplayer1value = 0, maxplayer2value = 0;
            foreach (ulong boardcards in Hand.Hands(0, ulong.MaxValue ^ board, 3))
            {
                foreach (ulong player1hand in Hand.Hands(0Ul, ulong.MaxValue ^ player1, 2))
                {
                    uint player1value = Hand.Evaluate(player1hand | boardcards, 5);
                    if (player1value > maxplayer1value) maxplayer1value = player1value;

                }
            }
            foreach (ulong boardcards in Hand.Hands(0, ulong.MaxValue ^ board, 3))
            {
                foreach (ulong player2hand in Hand.Hands(0UL, ulong.MaxValue ^ player2, 2))
                {
                    uint player2value = Hand.Evaluate(player2hand | boardcards, 5);
                    if (player2value > maxplayer2value) maxplayer2value = player2value;

                }
            }

            if (maxplayer1value > maxplayer2value)
            {
                player1win += 1.0;
            }
            else if (maxplayer2value > maxplayer1value)
            {
                player2win += 1.0;
            }
            else
            {
                player1win += 0.5;
                player2win += 0.5;
            }
            count++;
        }
        Console.WriteLine("Player1: {0:0.0000} Player2: {1:0.0000} Count: {2}", player1win / count * 100, player2win / count * 100, count);
        Console.ReadLine();       
    }
