Mastermind(Monkeyman576 vs. DarkLightA)

[MonkeyMan576]

Who is up to play mastermind?

Rules:
The codemaker selects four pegs from five colors(orange, green, red, blue, and yellow). Colors may be duplicated. The codebreaker tries to guess what the code is. Once the codebreaker guesses, the codemaker responds with "feedback", telling the codebreaker if the guess was the correct color in the correct position(c), the correct color in the wrong position(w), or not correct at all(b for "blank"). The codebreaker has 10 guesses to guess the correct code. I will be the codemaker the first game, after that we can discuss alternate arrangements.

Forum Rules: The codes will be posted in spoilers. It is against the rules for the codebreaker to view the spoilers, it is there for verification from the codemaker and the audience.

I'm so up for this!

Great, let's get started! Remember, don't read the spoilers, it has the answer to the game. Go ahead and get started by guessing four colors(You can use the first letter of the color if you want, (B=Blue, Y=Yellow, G=Green, O=Orange, R=Red, P=Purple)

Answer:

Spoiler:

R B B O

Alright. I've thought it over and I *think* guessing four colors is the optimal strategy for the beginning. I also considered guessing all one color, but that takes a lot of time to give information and gives no info on position. A strategy like a 2/2 split could also work, but I don't think it's ideal. Let's go with it:

YOGB

[MonkeyMan576]

1) YOGB - wwbb(two pegs are correct color but in wrong position, the other two are wrong color.)

[DarkLightA]

Interesting. I now know that there must be two of the same color in the answer, possibly three but unlikely.

Possibly a sub-optimal strategy, but I'll try:

RRYO

[MonkeyMan576]

1) YOGB - wwbb
2) RRYO - ccbb(two pegs are the correct color and correct position, the other two are wrong color in wrong position)

[DarkLightA]

You keep replying within minutes, very impressive. Too bad I don't notice ^.^

Alright. We're on the right track. Before I explore the correct ones further I'll take a look at G and B from the first line.

BGBG

[MonkeyMan576]

1) YOGB - wwbb
2) RRYO - ccbb(two pegs are the correct color and correct position, the other two are wrong color in wrong position)
3) BGBG - cwbb

[DarkLightA]

BBYO

[MonkeyMan576]

1) YOGB - wwbb
2) RRYO - ccbb(two pegs are the correct color and correct position, the other two are wrong color in wrong position)
3) BGBG - cwbb
4) BBYO - ccwb

Sorry, realized I made a mistake earlier. That should not have happened.
My bad. Revise your shot as you wish.

Okay, that means the Orange is probably right, because of the correct on 3 and 4, we probably need to switch R and B and choose another color for the final one. 2) gives us some clues as to the final color, with two wrong spots but right colors, so since B and O are are already accounted for, I'm guessing the last one is G

5) BORG
