What would you do?
Explore strategy, pressure and a reset. These are illustrative course-style previews: no account, saved score or personalised assessment.
The price changes. Does your decision?
The pot is 100 BB before the bet. Your supplied equity estimate is 30%. Compare calling with folding, assuming no further betting or rake.
Pot before bet100 BB
Opponent bets50 BB
Your equity estimate30%
25 BB100 BB
YOUR DECISION
Is the call worth its price?
Give me a hint
Divide the call by the final pot, including your call. Compare the result with 30%.
Reveal the explanation
Calling 50 BB makes a final pot of 200 BB. You need 25% equity. With the supplied 30% estimate, calling has higher expected value. The range estimate and assumptions matter.
Related learning: Pot odds, equity and the break-even call.
A message arrives. Did the hand change?
Your price-and-range analysis says fold. The opponent types:
“You just lost a pot. Bet you won’t call.”
No comparable history shows that this message predicts a bluff. Cards, price and action history are unchanged.
YOUR DECISION
What deserves more weight?
Give me a hint
The message is observed; its intention is inferred. Consider other explanations.
Reveal the explanation
Keep the fold here. The message could accompany a bluff, a value bet or simple banter. Adjust the technical baseline only when relevant evidence supports it.
Related learning: Hold your baseline under online pressure.
A sound call loses. What next?
The call needed 25% equity; your reasonable pre-reveal estimate was 30%. You lost and notice an urge to win the chips back quickly.
YOUR DECISION
Protect your next decision.
Give me a hint
Separate the information available before the reveal from the outcome. Notice the urge before acting.
Reveal the explanation
Review the decision using what you knew at the time. Pause, state the technical anchor and choose one process rule. Step away if you cannot follow it.
Related learning: Judge the decision, then reset.
Practise the reasoning, one decision at a time
Work through three free exercises: bluff-to-value ratios, the price of a call and counting a supplied range. Reveal the explanation, then change one input.

Pause where the decision gets interesting.
Three sourced tournament hands. Study a decision concept, then test it with a separate cash-game variation.
Mateos vs Lodden
Price the bluff.
A famous river bluff. What fold rate would make a bet worth taking?
2015 EPT Grand Final · Four players leftSee the decision and source
What do you need before judging the profitability of this bluff?
The exact effective river shove is not verified here. No historical fold-rate estimate or precise bluff threshold is claimed.
Affleck vs Duhamel
Review before the result.
Aces, a tournament-defining river and the danger of grading a decision from its outcome.
2010 WSOP Main Event · Day 8See the decision and source
What can the next river card establish about the turn decision?
The shove is reported approximately. Conflicting opening amounts and exact pot totals are omitted. This is a review-process lesson, not an endorsement of either complete tournament line.
Ivey vs Altman
Test the bluff-catching range.
A river check-raise from Ivey. Separate the extra call from the total raise, then test the range.
2018 WSOP Main Event · Day 4See the decision and source
What should justify a bluff-catch before seeing Ivey’s cards?
Exact starting pot, seat names and historical bluff frequencies are not supplied. The 434,000 extra call is arithmetic from the reported bet and raise-to amount.

Decision Desk · An original PSL river case
The same estimate, a different price
Heads-up river. No rake, ties, raises or further betting. Your hand never wins at showdown. Check has EV0; a called bluff loses the bet. The supplied fold probability is an exercise assumption, not an observed frequency. All amounts use the same exercise unit.
Pot 100. Bet 60. Supplied folds 45%. Choose check or bet 60. Calculate the break-even fold percentage and the bluff's immediate EV before revealing the explanation.
Review the reasoning
Break-even folds = 60/(100+60) = 37.5%. Bluff EV = 0.45×100 − 0.55×60 = +12. Check EV = 0. Under this model, bet 60. One successful bluff would not verify the supplied 45%.
Change one input
Keep the pot at 100 and supplied folds at 45%. Change only the proposed bet to 100. Which action does the model support now?
Compare the alternative
Break-even folds = 100/(100+100) = 50%. Bluff EV = 0.45×100 − 0.55×100 = −10. Check EV = 0, so check. The larger bet changes the price; the fold estimate stays 45%.
Compare the proposed bluff with checking at EV0. Other bet sizes and raising are outside this exercise. The break-even fold percentage is not the equilibrium bluff fraction of a betting range.
