UPDATE: How to reproduce:

• Make breakpoint on line 32.
• Click twice on random white piece.
• Run the following code in the console:

  var fromArray=[{x:1,y:7},{x:7,y:1},{x:5,y:6},{x:7,y:3},{x:2,y:5},{x:7,y:4},{x:4,y:4},{x:7,y:5},{x:5,y:7},{x:7,y:0},{x:7,y:7},{x:6,y:1},{x:5,y:6},{x:6,y:3},{x:5,y:5},{x:5,y:1},{x:6,y:4},{x:4,y:1},{x:4,y:4},{x:3,y:0},{x:3,y:6},{x:6,y:3},{x:3,y:7},{x:4,y:3},{x:4,y:6},{x:3,y:4},{x:4,y:7},{x:3,y:1},{x:4,y:6},{x:2,y:0},{x:4,y:5},{x:5,y:3},{x:3,y:4},{x:2,y:6},{x:3,y:3},{x:7,y:1},{x:4,y:3},{x:1,y:7},{x:0,y:7},{x:2,y:1},{x:1,y:6},{x:2,y:3},{x:1,y:5},{x:1,y:1},{x:2,y:4},{x:0,y:1},{x:1,y:3},{x:1,y:0},{x:0,y:6},{x:0,y:0},{x:2,y:7},{x:0,y:2}]

Resolved. The problem is in the allMoves method, because it doesn't simulate for king checks.

The AI checks all moves and selects one of them. In the same time the black king is in check but the AI doesn't care, because allMoves calls piece.getValidMoves(/* undefined */). Then the AI tries to make that turn, but the checks in game.moveSelected don't allow this. The turn isn't made and that's it.

We can solve it by adding true as the simulate argument of getValidMoves.
