Session Betting in Cricket
The complete guide to lambi pari, powerplay betting, and khai-lagai markets
Session betting lets you wager on runs scored in specific overs rather than the match result. Instead of picking a winner, you bet whether a team will score above or below a line in overs 1-6, 1-10, or the full innings.
This guide covers everything: what session betting means, how lambi pari works, the khai-lagai system, and how to find genuine value in these markets. Before placing any bets, ensure you understand betting laws in India.
What is Session Betting?
Session betting focuses on short segments of a cricket match. The bookmaker sets an over/under line for runs in that segment, and you bet Over (Yes) or Under (No).
Example: In an IPL match, you might see:
- Powerplay (overs 1-6): Over/Under 48.5 runs
- First 10 overs: Over/Under 82.5 runs
- Full innings: Over/Under 172.5 runs
You choose whether the batting team will score above or below each line.
Why Session Betting is Popular
| Advantage | Explanation |
|---|---|
| Multiple opportunities | Several betting markets per innings |
| Short duration | Results in 6-20 overs, not the whole match |
| Can win even if team loses | Your bet settles on runs, not match result |
| In-play action | Lines move ball-by-ball |
Lambi Pari Explained
Lambi Pari = "Long Bet"
Hindi slang for betting on the total runs in an entire innings — 20 overs in T20, 50 overs in ODI. Think of it as the Indian version of "Team Total Over/Under."
How Lambi Works
If the lambi line is 175, you bet:
- Yes (Lagai): Team scores 175 or more
- No (Khai): Team scores 174 or less
Lambi vs Match Winner
| Lambi Pari | Match Winner |
|---|---|
| Bet on run total | Bet on who wins |
| Can win even if team loses match | Only wins if team wins |
| Continuous outcome (runs) | Binary outcome (win/lose) |
Example
India bats first, scores 165, but Pakistan chases it down. A "Lambi Over 160" bet on India wins (165 > 160), even though India lost the match.
Khai and Lagai: Indian Betting Terms
These are the Hindi equivalents of Lay and Back:
Lagai (Back / Yes)
Score will EXCEED
Betting the team scores above the line
Khai (Lay / No)
Score will be BELOW
Betting the team scores under the line
The Bracket System
Indian markets quote sessions as a two-number bracket like "42-44":
Example: Line is "42-44"
42 (Khai/No) → You win if score is 41 or lower
44 (Lagai/Yes) → You win if score is 44 or higher
43 (The Gap) → Bookmaker's margin - rules vary by bookie
What happens if score lands on 43?
Rules vary by bookie — some void bets, some favour the house. Always check the rules before placing bracket bets.

Types of Session Bets
1. Powerplay Runs (Overs 1-6)
The most popular session market. Field restrictions (only 2 fielders outside the circle) boost scoring, creating high volatility.
Typical lines: 45-55 runs depending on venue and teams
Key factors:
- Opening batsmen quality
- New ball swing conditions
- Pitch type (green = lower, flat = higher)
- Boundary dimensions
2. First 10 Overs
Covers Powerplay plus 4 middle overs. Teams often consolidate after Powerplay aggression.
Typical lines: 75-90 runs in T20s
3. Middle Overs (7-15)
The "consolidation phase" — often the slowest scoring period. Spinners dominate, field spreads out.
Typical lines: 50-70 runs for this 9-over segment
4. Death Overs (16-20)
The most volatile session. Power-hitting, yorkers, chaos. Lines move dramatically ball-by-ball.
Typical lines: 40-60 runs depending on wickets in hand
Critical Factor: Wickets
A team at 120/2 has a much higher death-over projection than 120/6. Always factor in wickets in hand when assessing death over lines.
5. Full Innings (Lambi Pari)
Total runs in 20 overs (T20) or 50 overs (ODI).
Typical T20 lines: 160-180 runs depending on venue
How Bookmakers Set Lines
Pre-Match Factors
- Venue history: Average first innings scores, Powerplay averages
- Team batting strength: Current form, lineup quality
- Pitch reports: Green (lower), flat/dry (higher)
- Weather: Dew factor makes 2nd innings batting easier
In-Play Adjustments
Lines move every ball:
| Event | Line Movement |
|---|---|
| Four | Increases ~2-4 runs |
| Six | Increases ~4-6 runs |
| Dot ball | Decreases slightly |
| Wicket | Drops significantly (10-15 runs from Lambi) |
The Opportunity
Markets often overreact to events. A six might push the line too high, creating value for "No" bets.
Finding Value in Session Markets
The Expected Value Formula
EV = Stake × (Your Probability × Odds - 1)
Example:
You estimate 60% chance of exceeding the line
Odds offered: 2.0 (implying 50%)
EV = 1000 × (0.60 × 2.0 - 1) = +200
Positive EV means you have an edge.
How to Estimate Probability
- 1 Venue baseline: What's the typical Powerplay score here?
- 2 Current run rate: Are they ahead or behind pace?
- 3 Batting quality: Star batsmen at crease vs tail-enders?
- 4 Match situation: Wickets in hand, target pressure?

Venue Impact on Sessions
Different grounds produce vastly different scoring patterns:
| Venue | City | Powerplay Avg | T20 Total Avg |
|---|---|---|---|
| Rajiv Gandhi Stadium | Hyderabad | 55+ | 180-190 |
| Chinnaswamy | Bangalore | 52-55 | 180-190 |
| Wankhede | Mumbai | 50-52 | 175-185 |
| Eden Gardens | Kolkata | 48-50 | 165-175 |
| Chepauk | Chennai | 42-46 | 155-165 |
Key Insight
A 50-run Powerplay line is high for Chennai but low for Hyderabad. Always benchmark against venue-specific data.
Session Betting Strategies
1. Regression to the Mean
After an unusually big over (20+ runs), the market often overreacts. The next over is statistically likely to be closer to average.
Pro Tip
When a team scores 20+ in one over and the line spikes, consider betting "No" — the market usually overreacts.
2. Wicket Weightage
Each Powerplay wicket typically costs 10-15 runs from the final total. If two quick wickets fall, the market may over-drop.
Strategy: If a quality batsman (Kohli, SKY) comes in after a wicket, the lowered line may offer value on "Yes."
3. Pre-Match vs In-Play
| Timing | Best For |
|---|---|
| Pre-match | Lambi bets (based on venue/pitch analysis) |
| In-play | 6-over, 10-over sessions (react to live conditions) |
4. Stop Chasing the Rate
Mistake: Betting "Yes" immediately after a big over because momentum looks unstoppable.
Reality: The bookmaker already priced in the momentum. Often there's more value betting "No."
Bankroll Management
Session betting is high-frequency — multiple bets per match. Without discipline, losses accumulate fast.
Rules
- • Max 0.5 units (0.5% of bankroll) per session bet
- • No Martingale — never double after losses
- • Set a stop-loss per match (e.g., max 5% loss)
- • Pass is valid — don't bet every session

Common Mistakes to Avoid
| Mistake | Reality |
|---|---|
| Chasing momentum after big overs | Markets adjust faster than you think |
| Ignoring venue context | 50 runs means different things at Chennai vs Hyderabad |
| Doubling after losses | Leads to catastrophic bankroll damage |
| Betting every session | Only bet when you identify genuine value |
| Ignoring the bracket gap | Know your bookie's rules for scores landing in the gap |
Summary: Session Betting Checklist

- 2 Check the line — Is it above or below venue average?
- 3 Assess current situation — Run rate, wickets, batsmen at crease
- 4 Calculate your edge — Does your probability exceed implied odds?
- 5 Size appropriately — Max 0.5 units per session bet
- 6 Know the gap rules — What happens if score lands in the bracket?
Session Betting FAQs
Frequently Asked Questions
What is session betting in cricket?
Session betting is wagering on runs scored in a specific block of overs (e.g., overs 1-6 or 1-10) rather than the match outcome. Bookmakers set an over/under line, and you bet whether the team will score above or below that number.
What does lambi pari mean?
Lambi pari is Hindi slang meaning "long bet." It refers to betting on the total runs in an entire innings (20 overs in T20, 50 overs in ODI). It is the Indian equivalent of Western sportsbooks' Team Total Over/Under market.
What is the difference between khai and lagai?
Khai means Lay or No - betting the score will be BELOW the line. Lagai means Back or Yes - betting the score will EXCEED the line. These are standard terms in Indian betting exchanges.
How do bookmakers set session betting lines?
Bookmakers use historical venue data, team batting strength, pitch reports, weather conditions, and head-to-head records. Lines then adjust ball-by-ball during play based on boundaries, dot balls, and wickets.
What is powerplay betting?
Powerplay betting focuses on runs scored in overs 1-6 when fielding restrictions apply (only 2 fielders outside the 30-yard circle). It is the most popular session market due to high scoring and volatility.
How do I find value in session bets?
Compare your estimated probability of exceeding the line against the bookmaker's implied probability. If your estimate is higher, you have positive expected value (+EV). Use venue averages, current run rate, and match situation to form your estimate.
What does the bracket (e.g., 42-44) mean?
The bracket shows two numbers: the lower is for No/Khai bets (score must be 41 or less to win), the higher is for Yes/Lagai bets (score must be 44 or more to win). The gap (43) is the bookmaker's margin.
How much should I stake on session bets?
Never wager more than 0.5 units (0.5% of your bankroll) on a single session bet. Session betting is high-frequency with multiple opportunities per match, so strict bankroll management is essential.
