Defend pre, check-call flop, check turn, and fire a small river block/value bet with a strong showdown hand.
Flop comes T86 rainbow, a board that hits LJ’s opening range fairly well. Multiway, checking our entire range is the default—leading would isolate us against strong made hands and strong draws. BU fires a small c-bet into two players; with SPR around 4.5 and a strong showdown hand in middle pair, calling is preferred over raising. We’re getting a good price, and raising would mostly get action from better hands and strong draws.
Turn 4c adds a second club and drops SPR to under 2. After BU checks, we should continue checking and let BU decide whether to bluff or value-bet. If we bet, we mostly fold out worse hands and get called by better hands and strong club draws. Checking keeps our range protected and lets BU make a decision with their capped range.
River Th pairs our 8 and gives us a strong showdown hand. BU’s range is somewhat capped after checking turn, while LJ still has a strong range. A small block/value bet works well here—worse hands like 9x/Jx can call, and we also block some of BU’s natural bluff candidates. Betting large would mostly get called by better hands and fold out the hands we’re targeting for thin value.
