This is a high variance play, especially given this board texture, I see you getting 3 bet frequently. If he is a good tag, then he cant have KQ,AJ,AT,AA,JJ,TT since he wouldve raised preflop with those holdings, so his rage on this board given his actions and my assumptions is very narrow, I would put him on A7s, A8s, A9s, or JTs. So your read that tag is most likely on Axs is dead on. But even though you may be chopping and you did pick up a nice draw, that in itself is not a good reason to checkraise this turn especially when you consider the reality that you will be getting 3 bet by a better hand a certain amount of time, and even more so if your read on the tag is wrong and he is capable of limping on KQ or AJ. I would only checkraise in this situation if I strongly thought that the tag is capable of folding his ace, that to me is the only reason to consider when making this play, if you think the tag wont fold his ace, then youre better off just checking and calling and avoiding the risk of getting 3 bet. There are tags that simply wont fold a hand postflop especially online, and then there are tags that can make good laydowns.
