As promised our friend Samy89, wanted to review your Big Blind Defence hands to show you the power of his creation Poker Scientist.

He reviewed several hands submitted by our members using his GTO solver for each one of them. 

Even if you didn't submit a hand it is worth watching the video because we purposely picked Big Blind Defence as it is a very common spot. 

Thanks to everyone who submitted a hand for review and a big well down to our raffle winner ght3r who wins a free month of the software to try for themself.

If you are on the fence about a piece of software like this, the best way to make your mind up is to watch a video like this where all the features are on display. If you like the look of Poker Scientist, see below for more details and how to get 10% off.

Poker Scientist helps you understand the principles of poker as efficiently as possible.

The browser-based software gives you instant access to a GTO gameplan, containing billions of strategies for every relevant heads-up scenario. The gameplan was developed with simplification in mind, with Clustering offering a whole new way of understanding and internalising new strategies.

Poker Scientist's gameplan is calculated using computers that are several orders of magnitude more powerful than any desktop PC. The highly accurate solutions use the optimal number of bet and raise sizings. Solutions with this accuracy are not achievable for the average solver user on their home PCs.

Through two simplifications in the form of Line Elimination and Runout Clustering, Poker Scientist managed to overcome one of the major problems other solver tools have when it comes to learning and developing your own game efficiently.

Altogether, Poker Scientist offers you a GTO game plan with an innovative approach that's going take your poker game to a whole new level.
