12-Week Study Program Week #4 - Flop Defense | Weekly Coaching with Matt Hunt

Quick recap — Matt Hunt’s Week 4 coaching: “Flop Defense”

Main plot / purpose

• Matt defines “flop defense” as the obligation to defend your range enough to capture the EV you’re owed when facing aggression — not just avoiding being exploited, but avoiding unnecessary value loss.
• The session is practical and simulator-driven: Matt uses Octtopi sim screenshots and chat interaction to demonstrate how defense changes with bet size, position, stack depth, opener position, board texture, and multi-way action.

Big takeaways / highlights

1. The single most important variable on the flop: bet size

   • Bet size drives almost everything: fold/call/raise frequencies, future SPR, how polarized villain’s range is, and how easy it is to realize equity.
   • MDF is a useful concept but less clean on the flop than on the river. A simpler rule of thumb: smaller bets → continue/raise more; bigger bets → fold more / raise less. When raising vs big bets, prefer smaller raises.

2. Examples from the sims (concrete numbers)

   • Small flop bet (B25): fold ~39.4%, call ~42.8%, raise ~17.7%.
   • Bigger bets compress defense — B75: fold ~55.8%; B125: fold ~62%, call ~33%.
   • In-position makes a big difference: same B25 that you’d fold ~39% OOP, you’d fold only ~15.7% IP.

3. Stack depth matters

   • Shallower stacks → raise more often (and call less). Example: at 30bb you raise thin value more than at 60bb; at 20bb raises and shove incentives increase.
   • Deeper stacks → more calling, fewer raises; thin-value raising becomes harder as stacking-off ranges tighten.

4. Opener position vs your responses

   • You defend more vs later openers because their ranges are wider, but raising frequency doesn’t jump massively because later openers often bet less (they adjust).
   • Raising strategy should be based on the c-bet range, not the board alone.

5. Raise sizing vs villain sizing

   • If villain bets small, use a medium raise more often. If villain bets big, raise smaller (min/clickback) or occasionally shove — large raises into big bets usually make villain decisions easy.

6. Bluff selection by board texture (heuristics)

   • Rainbow boards: prefer front-door draws plus combo backdoors; choose bluffs that preserve useful showdown value and that unblock villain folders.
   • Two-tone boards: require suit interaction; prefer front-door flushes and high-/low-card combos that can beat second pair and carry extra equity.
   • Monotone boards: trickiest — include some bluffs without the flush (straight draws, some bottom-pair bluffs) and prefer flush draws with weaker kickers to better fold out ace-highs.

7. Multi-way bonus: facing a c-bet with action behind

   • Key question: how much action do you expect from players behind you?
   • If players behind will raise frequently (or have many strong hands), often call/fold (trap with strong hands) instead of raising and knocking them out.
   • Example: small c-bet on Q99 with button + big blind — the button calls wide and the big blind raises a lot; therefore the button’s strategy is call/fold, not raise.

Raise-size takeaway (short)

• Smaller villain bets → larger, medium raises from you are viable.
• Bigger villain bets → prefer small raises or shoves; avoid large intermediate raises that simplify opponent decisions.

Examples from the sims (recap)

• B25 (small): fold ~39.4%, call ~42.8%, raise ~17.7%
• B75: fold ~55.8%
• B125: fold ~62%, call ~33%
• Position effect: B25 fold OOP ~39% vs IP ~15.7%

Notable coach chatter, reactions & light moments

• Chat was active with welcomes and guesses: Steve, Andrew, Tyler, Gil, Jay, JLE, Thomas.
• Matt quizzed chat on the “most important thing” (bet size) and on frequency numbers (IP vs OOP).

• Banter highlights:

  “Steve has all the spoilers.” “No limit baby” — Thomas

• Matt wrapped exactly on the hour and said slides will be made available; he invited further Q&A on Discord.

Q&A highlights (short)

• MDF: solvers often defend less than MDF OOP and at/above MDF IP — MDF is cleaner on the river than the flop.
• Raise-size heuristics: raise smaller vs bigger villain bets; consider board texture, thin-value protection needs, and SPR.
• Multi-way: if facing bet+call and action left, raising is more conditional — often prefer call/fold unless behind ranges are weak.

Where to get the materials

• Slides and lesson materials will be posted on Octtopi Academy and Discord.
• Matt will be available on Discord for follow-ups.
• Next week’s topic: multi-way preflop focus.
