I was playing a hand at the casino the other day and I made a decision that I am not too sure about, let me know your thoughts.
CO has about 60bb behind, I have about 120bb, sb covers me
Preflop action: I am in the big blind with 9♠9♥, cutoff opens to 5bb, sb calls I elect to call.
sb checks, I check, CO bets 11bb sb calls I call
sb checks, I check, CO bets 21bb sb calls I call
sb checks, I check, CO checks and shows A7o, sb mucks.
I am wondering if checking is the right play on the river, my thinking was that if the CO was going to bet flop and turn on a relatively dry board they are very likely to have a seven and maybe a strong 9 (although I block 9's). I definitely think it was a mistake on the part of the CO to not bet this river, given the action up until then and how strong their holding was. I decided not to 3-bet this hand preflop to close out the action and keep hands weaker than mine in play, as the CO especially tended to raise a weaker range during this session especially from later positions. My reasoning for checking the river in the moment was to encourage the CO to bet again with a 7 or the case 9 so I could raise all in. Given the CO's hand, a min raise on the turn or flop most likely would have been called by him but I wanted to keep both the CO and SB in the pot so I elected to call in both spots.
