Chess Tips & Strategy to Win More Often (Free Online)

The chess tips that win the most games are these: run a short blunder check before every move, count attackers and defenders before you capture, learn to spot the four basic tactics (fork, pin, skewer and discovered attack), improve your worst-placed piece when there’s nothing to take, trade pieces when you’re ahead in material, put rooks on open files, and walk your king toward the center once the queens are off. Chess has no dice and no hidden information, so every one of those habits is a pure skill edge. You can practice them free in your browser at Offline Games Arcade, playing White against a computer opponent on Easy, Medium or Hard.

This guide assumes you already know how the pieces move, what castling and en passant are, and the difference between checkmate and stalemate. If any of that is shaky, start with our how to play Chess rules guide — it also covers the opening basics of controlling the center, developing knights and bishops, and castling early.

Run a blunder check before every move

Most games below expert level aren’t won by brilliant plans. They’re lost by leaving a piece where it can be taken for free — a “hanging” piece.

Before you play a move, ask three questions in this order:

What did their last move change? Look at the piece that just moved. What does it attack now? What did it stop defending, and what line did it open up behind it?
What can they check or capture after my move? Checks and captures are the forcing moves, so look at every one of them, even the ones that seem silly.
Is the piece I’m moving doing a job right now? If it’s the only defender of another piece, or it’s blocking a line to your king, moving it has a cost.

Count attackers and defenders before you capture

A piece being “defended” isn’t a yes-or-no question. When several pieces are aimed at the same square, count them.

If you have more attackers than they have defenders, you can usually win the piece. Two attackers against one defender wins it; two against two normally doesn’t.
Capture with the cheapest piece first. The standard values — pawn 1, knight 3, bishop 3, rook 5, queen 9 — are the same ones the computer opponent uses. If the first capture is made by your queen and a pawn takes back, the count was irrelevant.

Do the same count in reverse for your own pieces. A knight attacked twice and defended once is not safe, however solid it looks.

Learn the four tactics that decide most games

Tactics are short forcing sequences that win material. Four patterns cover the large majority of them.

The fork. One piece attacks two targets at once and only one can be saved. Knights are the classic forkers because nothing can block them, and a knight check that also hits the queen or a rook is the most common game-ending shot at beginner level.
The pin. A bishop, rook or queen attacks a piece that can’t move without exposing something more valuable behind it. If the piece behind is the king, the pinned piece can’t legally move at all. The follow-up is the important part: attack the pinned piece again, ideally with a pawn, because it can’t run.
The skewer. A pin turned around. The more valuable piece is in front, it has to move, and you take what was standing behind it.
The discovered attack. You move one piece out of the way and the piece behind it attacks. The piece that moved gets a free turn to do something nasty, because your opponent has to deal with the unmasked attacker.

A fifth idea ties them together: remove the defender. If a piece you want is guarded by exactly one other piece, capture, chase away or pin that guard first.

To find these in your own games, look for the raw ingredients before every move: two enemy pieces on the same line, an enemy king and queen a knight’s move apart, or any enemy piece with no defender at all. Undefended pieces are what tactics are made of.

With nothing to take, improve your worst piece

Plenty of positions have no tactic in them. That’s when players drift and make a move just to make a move. Instead, find the piece of yours that is doing the least and give it a better square.

Knights belong near the center. A knight in the middle of the board can reach up to eight squares; on the edge it reaches four at most, and in the corner only two.
Bishops need open diagonals. A bishop staring at its own pawns is barely a piece. Either move it outside the pawn chain or move the pawn that’s blocking it.
Rooks need open files. A file with no pawns on it is a road into the enemy position. Put a rook on it, and if you can, put the second rook behind the first.
A rook on the seventh rank is a monster. That’s the row where your opponent’s pawns started. A rook there attacks pawns from the side, where they can’t defend each other, and often pens the enemy king on its back row.

Trade pieces when you’re ahead

Being up a knight with every piece still on the board is a modest edge. Being up a knight with nothing else left except kings and pawns is usually decisive. The lead is the same; its share of what’s left has grown.

Ahead in material: trade pieces, keep pawns. Offer even exchanges of knights, bishops, rooks and queens. Keep your pawns, because one of them will need to promote.
Behind in material: do the opposite. Keep pieces on to create complications, and trade pawns to make the win harder to convert.

Finish the game: endgame essentials

Winning a piece isn’t winning the game. These are the habits that convert.

Activate your king. With the queens gone, the king stops being a liability and becomes a strong piece. Walk it toward the center and toward the pawns.
Learn the ladder mate. With two rooks, or a queen and a rook, against a lone king: one piece cuts off a rank so the king can’t cross it, the other checks on the next rank, and you alternate until the king runs out of board. It needs no help from your own king.
Push your passed pawns. A pawn with no enemy pawn in front of it or on either neighboring file ties down enemy pieces just by threatening to promote. Support it with a rook from behind and advance it.
Take the opposition in king-and-pawn endings. When the two kings face each other with one square between them, the side that doesn’t have to move holds the advantage, because the other king must step aside.
Check for stalemate before every quiet move. If the enemy king isn’t in check and has no legal move, the game is a draw no matter how far ahead you are. When your opponent has only a king left, make sure it always has one square to go to until you deliver mate.

Beat the computer at each level

You always play White here, so you always move first. The game keeps a separate win, loss and draw record for each difficulty, and it saves a game in progress, so you can close the tab mid-game and come back to it.

Easy plays random legal moves. Use it as a practice board: set up forks and pins on purpose, and rehearse the ladder mate until you can do it without a stalemate.
Medium scores each move on its own — what it captures, whether it gives check, and whether the piece lands on an attacked square. It doesn’t look at your reply. That means a threat against a piece it isn’t moving often goes unanswered, and two-move ideas like a fork set up with a quiet first move usually work.
Hard searches three moves ahead — its move, your reply and its follow-up — and values good squares as well as material. One-move tricks won’t land. Beat it with the slow stuff in this guide: never hang a piece, win small amounts of material safely, trade down, and convert in the endgame, where a plan runs longer than it can see.

When you want a break from 64 squares, the same calculating habits carry over to other games in the arcade:

Checkers — captures are forced, so you can calculate shots exactly; our checkers tips cover the patterns.
Reversi — teaches you that grabbing the most material right now is often wrong.
Four in a Row — double threats in their simplest form; a fork with discs.
Backgammon — planning around risk rather than certainty.
Mancala — counting ahead with no luck involved.
Nim — the opposition idea boiled down to matchsticks.
Tic Tac Toe — the two-minute way to show a child what a fork is.

FAQ

What is the most important chess tip for beginners? Stop giving pieces away for free. Before every move, check what your opponent’s last move attacks and what they can capture or check after yours. That one habit decides more beginner games than any opening.

How do I get better at spotting chess tactics? Learn the four basic patterns — fork, pin, skewer and discovered attack — and then look for their ingredients every move: undefended pieces, pieces lined up on the same file or diagonal, and a king that can be checked.

Should I trade pieces in chess? Trade pieces when you’re ahead in material, because your extra piece matters more as the board empties. When you’re behind, avoid piece trades and exchange pawns instead.

When should I bring my king out in chess? Once the queens have been exchanged and there are few pieces left to attack it. In the endgame an active king in the center is one of your strongest pieces.

Can I practice chess against the computer for free? Yes. Chess at Offline Games Arcade is free to play in your browser with no download or sign-up, against a computer opponent on three difficulty levels, with your record tracked for each.
