C-bet as IP Aggressor

Lesson 5 · When and how to c-bet in position, and what changes out of it · 32 practice questions

Why continuation bet?

After you raise preflop and villain calls from the big blind, you arrive at the flop with two edges: a range advantage (your range holds the overpairs and big cards his calling range mostly lacks) and position (you act last on every street). A continuation bet turns both edges into chips. Against the many unpaired hands in villain's range it wins the pot outright; against his medium hands it builds a pot while you are ahead; and because you bet strong hands and air with the same motion, he cannot fold only against your value.

Example. On K♠7♦2♣ you hold Q♥J♥ — no pair, no draw — and villain checks (pot 6). A bet of 2 needs only 2/(6+2) = 25% folds to break even, and MDF asks villain to continue with 75% of a range that mostly missed this flop. Against a one-third bet he will still fold plenty of hands that beat queen-high, so this is a range bet: bet. Because your kings and overpairs also bet small here, the line stays balanced.

Common mistake: c-betting only when you connect. If you bet only with a pair or better, villain can fold everything else and your c-bets stop making money.

Frequency vs size

Frequency and size move in opposite directions. On a dry board you bet a large share of your range for a small size; on a wet board you bet a smaller share for a large size. The reason is what a bet needs to accomplish. On K-7-2 nothing is coming, so a bet only has to fold out hands with no equity — cheap. On 9-8-7 two-tone, villain has flush draws, straight draws and made hands; a bet must charge those draws now, and it must come only from hands that can stand a raise.

Example. On 9♥8♥7♣ with K♣K♦ (pot 6), bet — and bet big. A bet of 4 (two-thirds pot) means villain needs 4/(6+4+4) = 29% equity to call and only has to defend 1 − 4/10 = 60% of his range, instead of 75% against a one-third bet. A flush draw with 9 outs (≈19%) is now paying a bad price; a small bet would have let it call correctly. On 9♦6♣4♥ with Q♣Q♦, by contrast, bet small: nothing needs protection, so you want the widest possible calling range.

Common mistake: one size for every board. A one-third bet on 9-8-7 is too cheap for the draws; a two-thirds bet on K-7-2 folds out the hands you wanted to keep calling.

When to check back

Not every flop wants a bet from the raiser. Check back in three situations. First, when the board smashes the caller's range: on low connected flops like 6-5-4, the big blind holds the straights, sets and two pairs, while your range is full of overcards that missed. Second, when you hold a medium hand with showdown value but little to gain from a bet — it gets called by better and folds out worse. Third, occasionally with a very strong hand on a dry board, to keep villain's bluffs in the pot.

Example. On 6♠5♦4♣ you hold A♣K♣ (pot 6). You have only 6 outs to a pair — three aces and three kings, about 13% on the turn — and even those cards make one pair on a board where villain already has straights and two pairs. A bet here folds out little that beats ace-high and gets called or raised by everything that does: check. The same logic applies to A♣K♦ on monotone Q♠J♠4♠ without a spade, and to 7♣7♦ on J♦T♥9♠, where every overcard and straight card is bad for you.

Common mistake: betting 'because I raised preflop'. Initiative is not a reason; a bet needs either fold equity or value, and on a board that favors the caller it usually has neither.

When the raiser is out of position

Raising preflop gives you the stronger range, but position decides how much of that edge you can use. Out of position — you open the small blind and the big blind calls, or you open the cutoff and the button calls — you act first on every street. You cannot check behind to take a free card, and every bet you make can be raised or floated by a player who sees your action before he decides. That changes the c-bet in three ways. Bet less often: the hands that liked a cheap range-bet in position, overcards with no draw and weak pairs, now check, because they cannot realize their equity against a player who acts last. Keep betting where your range is clearly ahead: dry, high boards like K-7-2 or Q-7-2, where top pairs and overpairs want worse hands to pay. And check the boards that hit the caller: low, connected flops like 7-6-5 or T-9-8 belong to his range, and a bet there gets called or raised by everything that matters.

Example. Small blind against the big blind, flop K♣7♦2♠, pot 6, with A♦K♠: bet small, about a third of the pot, because worse kings and pocket pairs call 2 into 6. Same seats on T♦9♠8♣ with A♠K♦: check; two overcards are behind most of what calls, and out of position you would have to give up on most turns. With 9♣8♣ on Q♠9♦4♣ from the cutoff against the button, second pair checks and calls a reasonable bet — a hand to reach showdown with, not to build a pot.

Common mistake: c-betting out of position with the same range you would use on the button. The bet that prints money in position turns into a donation when the caller gets to act last.

Key takeaways

• Dry, high board (K-7-2, A-8-3) → c-bet almost the whole range, one-third pot.
• Wet, two-tone (9-8-7, T-9-6) → c-bet value and strong draws only, two-thirds pot; check medium hands.
• Low connected (6-5-4, 7-6-5, 7-5-4) → the caller's board; check overcards and give up without a plan to bluff.
• Monotone without the suit (Q-J-4 all spades) → check overcards; an overpair checks or bets one-third pot, never big.
• Paired (T-T-5, 8-8-3) → bet small; the caller rarely has the pair.
• Raiser out of position (small blind vs big blind, cutoff vs button) → still bet dry high boards small with real hands; check low connected boards, air and medium pairs.
