The most important question before making a value bet is what hands your opponent can realistically call with.
Suppose you raise preflop, get called by the big blind, and continue betting on a coordinated flop. The opponent calls again on the turn. By the river, their range is already much narrower than it was before the flop.
You should not think about every possible hand combination equally. Instead, consider which combinations are consistent with the action. Some hands will have folded earlier, some will have raised, and others will have continued because they had sufficient equity or showdown value.
This process is closely connected to poker chart hands, because understanding which starting hands reach different postflop situations helps you estimate how wide an opponent's range can remain.
When evaluating a river value bet, ask three questions:
- What worse hands reach the river?
- Which of those worse hands will actually call?
- Which better hands are likely to call or raise?
The third question is particularly important when deciding between a thin value bet and a check. If your opponent's range contains many stronger hands and very few weaker calling hands, betting becomes less attractive.
