White to move — find the best continuation

How to recognize this tactic

In Chess960 the pieces start on unfamiliar squares, so tactics appear earlier and from unusual angles. Do not trust classical patterns — read the actual lines of the bishops, the rooks and the queen from where they really stand in this position.

This position hides a concrete tactic that wins material or mates. Start with the most forcing candidate moves — checks, captures and threats — and calculate each to a clear end before choosing; the winning line is usually the one the opponent cannot meet.

General method: before you move, list the forcing candidates — every check, every capture, every direct threat — and calculate those first. The solution to a tactic is almost always among them.

Position on the board

White: king g1, queen c4, rook d1 f1, pawn a2 e2 f2 h2 b3.

Black: king e8, rook g5, bishop e7, knight f6, pawn c5 b6 g6 d7 h7.

9 white and 9 black pieces are on the board; the puzzle position arises after move 24.

The position in numbers

White are ahead by 8 points of material (24 against 16; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.

The white king stands on g1, the black king on e8.

It is White to move on move 24, with 2 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.

White keeps 5 pawns, Black 5. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: c, d, g.

The White king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.

Solution & explanation

Main line

24. Kh1 Rh5 25. Qf4 d5 26. Rd3

Why it works

  • Great move! king to h1 keeps the pressure (+6.5).
  • queen to f4 develops smoothly.
  • Precise: rook to d3 is the top choice (+6.4).
  • You win decisive material (+6.4).
  • If instead Rg4, then Qa6 and you stay on top.

Move by move

  • 24. Kh1 — king to h1

Types in this puzzle

Winning blow

Find the strike that wins material by force.

A winning blow is a forced material gain that does not fit a single textbook motif. The general tactical recipe applies: spot loose pieces, an awkwardly placed king, overloaded lines. Go through the forcing moves in order of violence — checks, captures, threats — because most combinations start with one of them. Do not judge by feel: calculate the concrete line until the outcome is beyond doubt.

About this position

These pieces come from starting position #368.

SP-368 · ThroneGuard — The king starts in the middle of the back rank, on d or e, and neither knight begins in a corner.

The king starts on e1, the rooks on d1 and f1, the queen on h1.

The kingside rook already stands on f1, so castling short moves only the king, from e1 to g1.

A bishop starts in the corner on a1: it has a single diagonal, which the b-pawn unlocks, running out to h8.

Every pawn on the second rank is defended from the very first move.

The setup belongs to the ThroneGuard family; read right to left it becomes position 303.

The engine's main line opens with g4.

Morozov Balance Index: 26 of 100 — class C — noticeable edge. Engine evaluation of the starting position: +34 centipawns for White (depth 42, 400 000 000 nodes).
