Flop Analysis
Checking with second pair on this A‑high, two-tone board multiway is reasonable: we keep the pot manageable, avoid getting shoved on in a low‑SPR pot, and let the short stack define the hand.
The preflop over-open and then calling off versus a massive multiway shove with only second pair torch a huge amount of equity; fold early and protect the stack.

We should fold to this huge flop bet; second pair plus backdoor draw is nowhere near strong enough versus a short stack jamming into two players on an A‑high board. **Ranges:** CO flatted a massive open then effectively jams into two players on A‑K‑3 — that range is overwhelmingly Ax (AT+, AQ, AK), sets like 33, and strong draws; almost no worse Kx continues this way. **Math:** Calling 2110 into ~3987 means we need ~34.6% equity, but versus a range of mostly top pair+ and strong draws, K9s second pair has far less and is crushed by all Ax. **Board:** The A‑K‑3 with two hearts heavily favors strong made hands and nutty draws; our second pair is a classic bluff-catcher, not a stack-off hand in a multiway, low‑SPR pot. --- > **Takeaway:** When a short stack rips into multiple players on A‑high boards, overfold medium strength hands — their range is usually strong and our equity is too low.
Note: Calling off most of CO’s stack with only second pair versus a huge multiway flop bet is a major overplay; folding and preserving our stack is clearly higher EV.
With the pot already massive and villain having only ~30BB behind, checking turn is fine — there is no fold equity to generate, and we don’t need to protect second pair further in an effectively all‑in pot.
River checking is correct: second pair is a clear bluff-catcher and jamming 30BB into a 6000+BB pot almost never gets called by worse, so we just realize our equity and hope to win at showdown.
