Hi,

What's my equity with JThh vs 2s2c on Ah9s3c?

How does equilab come up with 35.05%? or how do you guys calculate your equity based on the outs we have vs 2s2c?

I'm still confused with these and any help would be very much appreciated.

Thanks.

Well, you have 6 outs - any J or T. Hitting only those by the river is about 25% chance but equilab takes into account you hitting flush or straight also. That is quite difficult to calculate manually and that is why we have equilab

Because of the heart on the flop you have a backdoor flush and with the 9 you have a backdoor straight. Backdoor is - you need runner runner to complete your hand. Using the rule of 4 and counting for any backdoor one out more. Your roughly equity is 6 outs for a J or T and 1 out for backdoor flush and 1 out for backdoor straight - (6+1+1)*4= 32% this is not exactly accurate but close enough to make a decision.
Also you have to take in account that if the board paired twice you also win the hand like Ah9s3c Ad 3d that’s also extra equity.
