1. About the Strategy

• A corridor is a pair of bets on opposite outcomes with a “gap”—the corridor—between the lines.
• Unlike an arbitrage (sure-bet) that guarantees profit, a corridor mainly limits losses while keeping a chance to win more than usual.
• The tactic is most effective in high-scoring sports such as basketball, tennis, or handball.

Core idea

1. Place two wagers in opposite directions (e.g., total over and total under).
2. If the final result lands in the gap, both bets win.
3. If it falls outside, only one bet loses, and the loss is small.

2. Practical Application

Example: Basketball

• Bet 1: Over 220 (odds 1.9) — 100 ₽
• Bet 2: Under 225 (odds 1.9) — 100 ₽

Scenarios:

1. < 220 points — only Bet 2 wins: 100 × 1.9 − 200 = −10 ₽
2. > 225 points — only Bet 1 wins: −10 ₽
3. 221 – 224 points (in the corridor) — 200 × 1.9 − 200 = +180 ₽

Example: Football

• Bet 1: Home Win (odds 2.2) — 100 ₽
• Bet 2: Away +1.5 Handicap (odds 2.2) — 100 ₽

Scenarios:

1. Home team wins 2 – 0 or more — +20 ₽
2. Draw or away win — +20 ₽
3. Home team wins 1 – 0 (corridor) — +240 ₽

Tip: odds around 2.0 or higher make corridors more attractive; at 1.9 the loss is small, but the chance to “hit” remains.

3. How Corridors Form

Live Betting

• Place the first part before kick-off.
• During the game wait for the odds to move and take the opposite outcome.
• Risk: failing to catch the right odds or the match taking an unexpected turn.

Prematch & Line Movement

• Lines open days in advance; heavy money or news can shift odds sharply.
• Example: star player’s status unknown. Bet early, wait for confirmation, then place the second wager on the moved line.

4. Finding Corridors

• Experience from hundreds or thousands of bets.
• A feel for how odds and trends move.
• Ability to calculate margin and probability on the fly.

Player’s toolkit:

• Line-movement stats;
• Fast reaction in live markets;
• Corridor calculator for instant P&L estimates.

5. Takeaways

Pros

• Minimal risk with well-chosen odds.
• High upside when the result lands in the gap.

Cons

• Constant monitoring of lines and news is required.
• Needs experience and quick reactions.

Corridors are a balanced strategy for bettors ready to invest time in analysis and swift live actions.
