White Faced General in Xiangqi: The 白脸将 Checkmate

About the name

白脸将 translates literally as white-faced general, and 对面笑 as smiling face to face. Chinese writers explain the colourful wording in different ways, but the practical meaning is agreed: the two Generals would be looking straight at each other down an empty file, which the rules forbid, and the attacker exploits that ban. Some Chinese lists also carry a separate, broader entry, 借帅力, borrowing the General's strength, for any attack in which the General's file control helps.

If you have read our guide to the flying general rule, this is where the rule stops being a curiosity and starts winning games.

How the General controls a file

Because the Generals may never share a file with nothing between them, a General looking down an open file makes every point on that file off-limits to the enemy General. Put your General on its home point with the central file completely clear, and the enemy General can no longer use the palace centre, its own home point, or the middle of its palace's front edge. Its world shrinks to the two side files of the palace.

Those side files, the rib files, are where the mate happens. A General pushed onto a rib file can only move along it or back toward the centre, and the centre is gone. One piece checking along that rib file is frequently enough.

Strictly speaking, your General never gives check in this pattern. A move that left the two Generals facing each other would be illegal for whoever played it, so the General's power is pure denial. It removes points from the enemy General, and another piece does the checking.

Example one: the Chariot swing

Black's General stands on the back corner of the palace on Red's left, and one Black Advisor is on the opposite back corner. The central file is completely empty. Red's General is on its home point, and a Red Chariot sits on Black's side of the river, on the rank nearest the river, at the right-hand edge of the board. Red to move.

The Chariot swings across that rank to the left rib file and checks straight up it. The General cannot step forward, since that point is on the Chariot's file. It cannot step into the middle of the back rank, since that would leave it face to face with the Red General. The Advisor's only move, into the palace centre, does not block the Chariot. Checkmate, and XiangqiPlay's rules engine agrees that Black has no legal move.

The Red General never moved, yet it covered the key point. Shift it one step to the side, and the same Chariot swing lets the Black General escape to the middle of its back rank.

Example two: a Cannon behind its own Soldier

Now a Cannon version. Black's General is on the back corner on Red's right, with one Black Advisor on the other back corner. A Red Soldier has crossed the river and stands on Black's soldier row, on the right rib file. The Red General is at home with the central file clear, and a Red Cannon is still on its starting point on Red's left.

The Cannon slides along its rank to the front-right corner of Red's own palace, a point players know from the palcorner cannon opening, and that puts it on the right rib file behind the Soldier. With exactly one piece between them, the Soldier becomes the screen and the Black General is in check. Stepping forward leaves it on the same file behind the same screen, stepping into the centre faces the Red General, and no Black piece can reach the rib file to add a second screen. Checkmate again.

When the face is covered

Go back to the Chariot example and add a Black Advisor in the palace centre. The Chariot swing is still check, but the central file is now blocked, so the General can step into the middle of its back rank. The centre Advisor can even step forward to the front-left corner of the palace and block the Chariot. One piece on the file ruins the pattern.

Your own pieces count too. Put a Red Advisor in the centre of Red's palace and replay the Chariot swing: the Black General walks into the middle of its back rank, because the Red General's view is covered. Before you play for this mate, clear your own central file.

As the defender, the lesson runs the other way. Keep a piece on the file between the Generals whenever your General is short of room, and think twice before trading off the last one. That piece is pinned in place, since moving it would leave the Generals facing, so expect the attacker to aim at it.

A cousin of the iron bolt

If you know the iron bolt, 铁门栓, you already know half of this mate. There, a Cannon on the central file keeps the enemy General out of the centre while a Chariot or Soldier closes the net. The white faced general hands that job to your General, which never needs a screen and cannot be traded off, leaving the Cannon free for other work.

That matters most in endgames. Once the Cannons are gone, the General is often the cheapest piece to hold the central file, because it was going to stand in the palace anyway, and a single Chariot or Soldier working with it can be enough to finish.

Spotting it in your own games

The white faced general belongs mostly to endgames, where Advisors and Elephants have been traded and files are open. When you have a Chariot, or a Cannon with a screen, and the enemy General is on a rib file, ask one question: is the file in front of my General clear all the way to the enemy palace? If it is, the centre is already yours.

Your General can also step onto a rib file of its own palace. That moves its control to a side file, and the same idea works there, with the attacking piece checking on a different file.

A useful habit in any endgame is to glance down the file your General stands on after every exchange. The moment it opens, count the enemy General's remaining points. Often only two or three are left, and a single check covers them.

Mind the risk. Opening the file in front of your own General also opens it for the opponent's Chariots and Cannons, so check your own safety before you strip away your defenders.
