No, because it looks like it's all going to go in either right now, or on the turn, so it's effectively more like a 2800 chip all-in you're calling. Assuming the button comes along the whole way too, you're getting better than 2-1 odds, which seems favorable, but not when you factor in the chances that you're drawing close to dead against a boat or a better flush draw. Also, it's almost guaranteed that two of your outs are no good, since they'll make a boat for someone. In particular, that Ac is bad news for you, as it means you're probably going broke to AJ.

Now that I've said that, let me look at the results. Okay, you would have won, but I was right that you only had 7 valid flush outs. Also, any 8, 9, K or A on the river makes you lose. I'll go look up the exact odds for you: 22.15% to win after the flop. That's 3.5-1, and you'd be committing about 2700 to win 5750, which is only 2.1-1, so even if you knew the opponents had those exact cards, you'd be bad to call. Plus, you could easily have been drawing dead to a runner-runner straight flush.

What about a best-case scenario, with you up against something like AA and KK, neither of which has a club? Then you have 29.24% odds, which is 2.4-1... still not enough.

So, yeah. Don't chase flushes in big pots with a pair on board. If you'd called, they'd both be posting to bad beat forums right now, calling you a donk... and they'd be right.

preflop is really really bad. flop is played fine.

try not to question your play just because the club hit and you would have won a big pot. that is called being "results oriented" and it's bad

Fold preflop

As played, check fold flop. I hate pushing money in with a 7 high flush on a paired board.
