Originally posted by tomtom232Well white already has the distant opposition of kings but if the king moves first he gives that up. I suppose he can get it back with a bishop move later though so getting the king up as quickly as possible is a good plan also, I don't have a board handy, just doing an overview. Even without a board I can see a variation where white sacs the bishop.

Originally posted by sonhousethe white king never moves and the bishops are not sacked anyway black would not take the bishop he would go after the pawn because winning the pawn ensures the draw.

i think white can win because he has the bishop i know black can hide in the corner but maybe its possible. hey tomtom why dont we play a game with that set position? we'll find out once and for all?
How would that prove it? What if one of you plays a suboptimal move?

That doesn't win.

i think its a drawn game black king goes to the left corner and just plays patty cake in the corner until 50 moves is up.
Nope. Also this contradicts what you said earlier.

Originally posted by tomtom232I first looked at King moves, and realized that isn't getting anywhere. That leaves the Bishop, as the pawn is blocked at the moment. So where can the Bishop go? The first idea was to block the d-pawn via 1. Bd6, but that accomplishes nothing after 1...Kf7 2. a4 Ke6 and now either 3. B moves, Kd5 gets inside the square of the pawn or 3. a5? KxB and again is inside the square of the pawn.

So now we know that the Bishop must move, and Bd6 is a bad idea. Bc5 doesn't work for similar reasons (play it out and see). I can't see moving the Bishop backward off of the a3-f8 diagonal, and e7 and g8 are obviously bad. That leaves 1. Bb4.
After 1. Bb4 the black King must move, or it will never get inside the pawn's square (1... d5 2. a4 and the pawn marches freely). So 1...Kf7, toward the a-file. 2. a4 (naturally) and now what will black do? He can go behind the d-pawn with 2. Ke8, or he can go in front of it with 2...Ke6.
If 2...Ke8, 3. a5 Kd8 (what else is there?) 4. Bd6! (prevents Kc7) Kc8 5. a6! (prevents Kb7) and now the black King has to shuttle back to d8 and the pawn goes to a8 without a problem.
If 2...Ke6, 3. a5 Kd5 (still moving closer to the a-file) 4. a6 Kc6 (still trying to catch the pawn) and now the winner is 5. Ba5!. The black King can never get in front of the a-pawn to stop it. It will eventually have to leave the c6 square, and then the pawn will march home.
Here's the summary:
1. Bb4 Kf7 2. a4 Ke8 3. a5 Kd8 4. Bd6 Kc8 5. a6 (1-0)
-or-
1. Bb4 Kf7 2. a4 Ke6 3. a5 Kd5 4. a6 Kc6 5. Ba5 (1-0)
