Facing a river shove after we check, we should call off with 88 and two pair, given the price and our equity versus a wide jamming range.
Flop A87dd is very favorable for CO’s range, so from the BB we should mostly check. With middle pair and a backdoor flush draw, checking is the standard line—our hand is strong enough to continue but not strong enough to lead into CO’s range advantage.
CO bets 2.5 into 4.5; calling is the standard response. We’re getting a good price, and 88 has solid equity versus CO’s c-betting range on this texture. Solver prefers a lot of checking on this paired board, but calling the small c-bet is very reasonable.
Turn 7h pairs the board and gives us 88 with a 7 kicker. Solver prefers checking this card a lot, but a small lead is acceptable as a mix. The 2.9BB bet is a reasonable sizing, though checking slightly more often is preferred.
River 5s is a brick; CO’s range is still ahead overall. With 88 and two pair, we should check and let CO decide how to proceed. Solver likes a small block bet sometimes, but checking is the main line.
CO jams 22.6 into 15.3, so we’re calling 18.6 to win 37.9, needing about 26% equity. Solver shows this combo mixing between calling and shoving, but once we check and face the shove, calling is the standard response—our hand is too strong to fold versus a wide jamming range.
