Whuvars4.dll

From PokerAI

A 'freeware' Winholdem dll which provides a primitive capability to give a formula use of internal variables and short-circuiting (conditional evaluation of other formulae), but exists primarily to offer an iterator which calculates win probabilities against opponents who have been placed on a range of hands. It returns some statistical information about readiness to bet pre-flop which can be used to assign the hand range. The inbuilt Winholdem iterator assumes opponents can have all possible cards, and thus tends to overestimate the chances of a hand whose principal virtue is the rank of the pocket cards.

The evolution of the dll can be traced in the long Winholdem forum thread dll$prwin
