Questions are:

- what's "standard" opening bet size IP HU: 2BB, 2,5BB, 3BB ? Does it depend on: *villain: his 3-bet pre freq, aggro style,... ; *stack sizes + stakes; *just upon us: what is optimum for our developed game style (let the villain adjust to our style, but also we could have possibility to adjust to his game style if necessary)   // these are my thoughts

- what's our optimal bet size on flop OOP when we 3-bet pre and we get called under assumption we c-bet with High % as pre 3-bettor (1/2 pot, ~>6/10 pot, something else or depends how we hit flop/board texture or upon villain or upon many factors i.e. combination of counted factors +...) ?

- in which situations we call opponent's turn bet IP(we don't have enough strong hand for re raise) knowing there's  big risk we might fold river bet (turn bet size vs pot size, our equity, our FE when we plan to shove river as (semi)-bluff and similar...)?

- when we hit river (nuts or 2nd nuts) and we play OOP and we are deep(opponent just called our turn bet), what's optimal value bet (thin, half pot, full pot, ~65-80% pot, or again depends upon villain, hand dynamics, our image, history vs this villain, or upon many factors or just: the best value bet is the one that u think opponent is calling)?  Do we ever c/r nuts on river?

ty for the advices in advance

best regards
