Answers.Body: <p>In addition to the other answer, you can see the results from Stockfish 13+ NNUE at depth = 78 (half moves, so 39 moves). All lines are evaluated at <strong>0.0</strong> (<a href="https://lichess.org/analysis/standard/8/p7/P7/k3p3/3bKp2/3B1P2/8/8_b_-_-_15_8" rel="nofollow noreferrer">Position on Lichess</a>).</p>
  <p><strong>This is a draw</strong> (with perfect play). There is no way to make progress. There's always enough time for the other side to hold against your attempt to make progress.</p>
  <p>Note: diagrams below have a1 in the lower left.</p>
  <pre><code>[FEN &quot;8/pB6/P7/4pK2/3b1p2/5P2/3k4/8 w - - 0 1&quot;]

  <p>Regarding <em>bringing the Black king to b5 or a5</em> I would like to see the line.
  If the line is centered around &quot;hoping White makes a mistake&quot; that is fine for practical chances as long as it doesn't objectively lose, though objectively the line would still seem to be a draw. And White can't capture on e5 or f4.</p>
  <p>For example, in the line below, once the Black king reaches b5 then White has two ways to hold with (5. Bd3+) and (5. Bb7). These are the only two moves. Black's king can reach a5 but White's king can blockade on e4.</p>
  <pre><code>[FEN &quot;8/pB6/P7/4pK2/3b1p2/5P2/3k4/8 w - - 0 1&quot;]
  
  1. Ke6 Ke3 2. Bd5 Kd3 3. Be4+ Kc4 4. Kf5 Kb5 5. Bd3+ Kc6 6. Be4+ Kc5 7. Bd3 {Eval = 0.0 at depth 55.} (5. Bb7 Ba1 6. Ke4 Ka5 7. Kf5 Kb4 8. Be4 Bd4 9. Bd3 Kc3 10. Be2 Kb3 11. Bd1+ Kb4 12. Be2 Bc3 {Eval = 0.0 at depth 55.}) (5... Ka5 Ke4 {White can respond with 6. Ke4, Be2, Bf1, Bc4, and Ke6 with each line receiving an eval of 0.0, depth = 70.})

The engine evaluates both of those moves as -1.89 (after searching 30 plies deep), but the King move evaluates as -0.12.  Of course, even making one of the Bishop moves, White will still need to make some kind of mistake somewhere down the line in order for Black to get a win.

  Regarding *bringing the Black king to b5 or a5* I would like to see the line.
  If the line is centered around "hoping White makes a mistake" that is fine for practical chances as long as it doesn't objectively lose, though objectively the line would still seem to be a draw. And White can't capture on e5 or f4.
  
  For example, in the line below, once the Black king reaches b5 then White has two ways to hold with (5. Bd3+) and (5. Bb7). These are the only two moves. Black's king can reach a5 but White's king can blockade on e4.
