On a very connected, multiway flop, top pair with a backdoor draw should mostly check; once we face a 3-bet and cold-call, folding is the disciplined choice.
Three-way on Jc-7c-9h, the board is very connected and draw-heavy, and HJ/BU have a slight range advantage. Solver leans toward checking a lot here and mixing in a small c-bet; our 4.4BB bet is a bit too big and polarizes us on a texture where we want a more protected range.
Note: C-bet sizing is too large on a very connected, multiway flop; prefer checking or a small bet with top pair + backdoor hearts.
After we bet, HJ 3-bets and BU cold-calls, which massively tightens their ranges toward overpairs, strong sets, and nut flush draws. Our top pair with a backdoor heart draw is dominated by most of that range and doesn’t have the equity to continue multiway, even with the attractive price. Folding is the correct, disciplined decision.
