Hello,
I am a new HU player and trying to grasp some things about hands strength.
Can someone tell me a tool which can calculate how many of the 1326 hands
are bitten preflop by a given hand?
For example how many hands are bitten preflop by QTo and how many by K6o?
I really appreciate all the answers given.

Bitten? I presume you mean beaten. You shouldn't just consider whether your hand is winning pre-flop or not. You need to consider how well a hand plays against a range, including with post-flop play.

As a starting point, download Equilab (it's free).

I can tell you that the hands that are 'beating' QTo pre-flop are 22+, Ax, Kx, QJ+, QTs, which is 466 combos, or 35% of hands, but there are many other hands that have decent playability, such as suited connectors.

In deep stack heads up play, most players can be profitable with over 85% of hands on the button, and they can defend about 50% of hands vs a button open. If you get QTo, you shouldn't be thinking "Am I ahead?" You should be thinking "Am I going to win often enough - either by making the best hand or by bluffing - for it to be played profitably?"

ArtyMcFly I really appreciate your super fast and detailed answer and I am sorry about my English.

I downloaded Equilab (Pokerstars send me an email that I should not have it open while I am playing). I put QTo on the SB and random on the BB and it shows that QT wins 57.29% of the time. I am I doing something wrong? How did you calculate the 466 combos, or 35% of hands that beat QTo?

My question came up from playing HyperTurbo HUSNG and studying Nash Equilibrium Push or Fold tables. I noticed that QTo has "20+" blinds for the pusher, while K6o has "15.1" meaning that K6o is weaker for a push.

At the same time I see that K6o beats QTo by 55.85%. Here K6o looks stronger than QTo. Since K6o beats QTo why it is weaker in Nash tables?

I hope I did not confuse you!

No, you're just misunderstanding what Equilab is telling you. QT has 57% equity, but that doesn't mean 43% of hands are stronger than it. For example, AA crushes QTo while QTo doesn't crush plenty of hands it's ahead of (for example, even a hand like 54s does ok vs QT despite being behind).

Because it's not a question of how hands do against each other, it's a question of how hands do against the calling range. QTo does much better than K6o against 66, 77, 88, 99, blocks TT, and also does better against hands like Q2-Q9 and K7-K9. It will also do better against a whole bunch of middling stuff like 98o and 76s.

On the flip side, K6o only does much better than QTo against hands like JJ, QQ, and QJ, and maybe K2o-K5o.

Raw equity against each other isn't what nash considers at all.

Also @ whatever mod moved this to the HUNL forum, this is definitely more appropriate for either BQ (where it was originally posted) or the husng forum (given it's discussing shallow nash stuff).

Duncelanas I see, it makes sense. I really enjoyed your answer.

Please how can I make calculations like the above for a given hand?
