Iso-raising pre and c-betting are fine, but jamming over the flop check-raise with just top pair overplays our hand badly at this SPR.
Flop Analysis
Betting here is good — we have top pair on a wet board, range advantage as the preflop raiser, and an SPR that comfortably allows building a pot versus worse hands and draws.
**Board:** Dynamic, low/mid connected with a flush draw; this favors the blinds/limper slightly in nutted combos (straights, sets, two pair) but we still have many strong overpairs and top pairs.
**Ranges:** Our BTN iso range is much stronger and higher-card heavy, so c-betting with top pair plus overcard kicker denies equity from overcards and draws (Tx, 8x, diamond draws) and extracts value from weaker 9x and 7x.
**Sizing:** Around half-pot is fine here: it charges draws, sets up stacks by the river, and doesn’t over-commit us if raised.

> **Takeaway:** In limped, low-Spr pots, top pair from the preflop raiser should usually bet for value on wet textures, but we still need a plan versus aggression.
Flop Analysis
Facing the flop check-raise, we should mostly call and continue; jamming over the raise with just top pair turns our hand into a bluff and stacks off too light against a very strong range.
**Ranges:** After check-raising into the preflop aggressor on this coordinated board, BB is heavily weighted toward strong value (sets, 68 for a straight, two pair) plus strong draws (nut/strong diamond draws, combo draws like pair+draw); top pair without a diamond sits in the middle of our range and is not strong enough to 3-bet jam for value.
**Math:** We are getting ~2.3:1 to call (need about 30% equity), which top pair with an overcard kicker will have comfortably versus a value+draw-heavy check-raising range, whereas shoving gives BB great odds to continue only with hands that crush us or have big equity.
**Plan:** Calling keeps in bluffs and dominated draws, allows us to realize our equity in position, and lets us fold later versus huge turn aggression on bad runouts; jamming removes their bluffs and isolates us versus the very top of BB’s range.
---
> **Takeaway:** Versus flop check-raises on wet boards at medium SPR, treat top pair as a call-and-evaluate bluff-catcher, not a hand to 3-bet shove.
Note: Shoving over the flop check-raise with top pair drastically overplays our hand; calling with position and an SPR under 3 is much higher EV.
